November 25: Sixteen hydropower projects have obtained construction and power generation licenses from the Department of Electricity Development in the first four months of the current Fiscal Year 2077/78.
According to the Department, 16 hydropower projects with capacity of more than 1 MW have been given permission for construction and generation of electricity. The total capacity of these projects is 379.51 MW.
Moreover, the license period of these projects is 35 years, ie till 2112 BS. After that, the projects will be owned by the Government of Nepal.
In the corresponding period last year, only six projects had obtained construction permits. However, the number of projects that received the construction permits has increased in the current fiscal year.
The department said that the number of projects receiving construction and power generation permits has increased due to the fast-track approach of the government. A senior official of the department informed that the applications for the license through fast track will not remain pending like before. He said that now the promoter companies have started getting licenses in a short time.
The biggest project to get construction permit is Tamor Mewa Hydropower Project. The project to be built in Taplejung has been allowed to generate 128 MW of electricity. Similarly, the second largest project is 86.59 MW Landruk and the third is 70 MW Dudhkoshi-2 Hydropower Project.
Among the projects that have been given permit for construction are 14.7 MW Mudi Khola, 13.42 MW Midim and 11.05 MW Sunigadh Hydropower Project. Other 10 projects have a capacity of less than 10 MW.


Infrastructure built in the post independence period:-storage Dams on rivers Sutlej, Beas and the Ravi and the Canal infrastructure for utilization of stored waters
Multipurpose projects were planned over rivers, Sutlej, Beas and Ravi for storage of water by constructing dams. To utilize the stored water for irrigation, there was substantial expansion of infrastructure by constructing additional network of canals and remodeling the existing canals in the post independence period. Construction on Bhakra Dam was started in early fifties and completed in 1963 at a cost of Rs. 255.85 crore. The Bhakra Dam has a live storage capacity of about 5.60 MAF. Power Houses comprising five units each were built on left and right side, having a total installed capacity of 450 MW and 600 MW respectively. The installed capacity of the Power House on the left side was increased to 540 MW during the period 1981-85 and that of power house on the right side was increased to 785.00 MW during the period of 1996-2001.
Nangal Dam was constructed about 13 Km downstream of Bhakra Dam to pass a flood discharge of 3,50,000 Cs and to provide a balancing reservoir to smoothen out the diurnal variation in water released after generation of electricity at the above power plants.
Construction of Nangal Hydel Channel, which off takes from Nangal Dam, with a capacity of 12500 Cs and length of 61 Km was completed in 1954. Two Power Houses, namely Ganguwal Power House and Kotla Power House, each with an installed capacity of about 77MW, were constructed on Nangal Hydel Channel. The Bhakra Main Line Canal with a capacity of 12455 Cs, is an extension of Nangal Hydel Channel and primarily carries Sutlej waters for the States of Punjab, Haryana and Rajasthan and drinking water supply to Delhi and Chandigarh. The B.M.L canal which has a length of about 164 Km, (out of which 159 Km falls in Punjab), was built during the period 1950-54 to carry Sutlej waters.
The Ropar Headworks, which was constructed in the year 1874-82 for supply of Sutlej waters to Punjab areas through old Sirhind Canal System, was remodeled in 1952-54 for utilization of waters stored by Bhakra Dam.
The Ferozepur Headwork which was constructed in the year 1927, for the purpose of supply of Sutlej-Beas waters to Bikaner Canal and Eastern Canal and the canal network now in Pakistan, lost much of its utility after the partition of the country in 1947. The headworks came within firing range of Pakistan, therefore, to ensure uninterrupted water supplies to Bikaner and Eastern Canals and proper utilization of waters of rivers Ravi and Beas, Harike Headwork was constructed in the year 1954-55, deep inside Indian Territory.
The Madhopur Beas link, having a capacity of 10,000 Cs was built during 1955-57, linking river Ravi with Beas at Harike. The Rajasthan canal with a capacity of 18500 Cs, off taking from Harike Headworks was constructed during 1958-1961, for supply of Ravi-Beas waters to Rajasthan. This canal runs in a length of 149.53 Km in Ferozepur, Muktsar and Faridkot districts of Punjab. The Ferozepur Feeder off-taking from Harike Headworks was constructed in the year 1952-53. This canal, with a capacity of 11192 Cs, runs in a length of 51.30 Km and supplies Ravi-Beas waters to Sirhind Feeder and Eastern Canal systems of Punjab and Bikaner Canal of Rajasthan.
The infrastructure thus created ensured best possible utilization of Ravi-Beas waters on run off the river basis, pending construction of storage dams on rivers Beas and Ravi. The water of river Beas was somewhat tamed by constructing a storage dam at Pong (1974) with a capacity of 5.91 MAF. Pong Power House having an installed capacity of 360 MW ( 6 units of 60 MW each) was constructed downstream of Pong Dam. The Pong Dam was constructed at a cost of Rs. 302.00 crore.
3.82 MAF of Beas water was diverted through Beas Sutlej Link (1977) into Bhakra reservoir through a diversion dam at Pandoh , constructed upstream of Pong Dam. A Power House with an installed capacity of 990 MW (6unit of 165 MW each) was constructed at Dehar, where a fall of 1000’ exists, before diversion of water into Bhakra reservoir. The Beas Sutlej Link Project was constructed at a cost of Rs. 396.85 crore. The capital works of Beas project, were executed by the Beas construction Board, constituted under the Punjab Reorganisation Act, 1996 and the expenditure was met out of Central Assistance given to the partner states (Punjab, Haryana & Rajasthan) by way of loan. After completion of works of Beas Project, these were taken over by the Bhakra Beas Management Board ( BBMB).
For proper utilization of Beas water for irrigation, Shanehar Headwork was constructed in the year 1983, downstream of Pong Dam. The Mukerian Hydel Channel which was constructed in 1982 , which off-takes from this headwork and after production of electricity at four Power Houses, having a total installed capacity of 207 MW, waters of river Beas are relesed for utilization at Harike.
The Ranjit Sagar Dam on river Ravi, constructed 24 Km upstream of Madhopur Headworks, was commissioned in the year 2000. Expenditure of Rs. 3745.00 crore has been incurred on the project out of which Rs. 3495.22 crore was funded out of Punjab’s plan allocations, and a meager loan assistance of Rs. 249.78 crore was provided by Government of India. The dam has been constructed with the objective of power generation and full use of utilizable Ravi waters. The dam has a storage capacity of 1.9 MAF. A Power House, with a total installed capacity of 600 MW ( 4 units of 150 MW each) has been constructed downstream of the Dam.
The Shahpur Kandi dam project has been proposed for construction 11 Km downstream of Ranjit Sagar Dam. The Shahpurkandi Dam will act as a balancing reservoir to enable Ranjit Sagar Dam to function as a peaking station for optimum power generation during peak hours and to ensure uniform releases of water to the canal system off-taking from Madhopur Headworks.


SACRAMENTO, California – The U.S. Army Corps of Engineers Sacramento District awarded an $8.58 million construction contract July 28 to Macro-Z Technology Company of Santa Ana for the relocation and construction of a U.S. Forest Service administrative building and warehouse in Kernville.
The contract includes construction of a 5,500-square-foot administrative office building and 2,700 square feet of warehouse space. The existing USFS facilities currently sit in the footprint of the 300-foot-wide emergency spillway to be built between the main and auxiliary dams as part of the Isabella Lake Dam Safety Modification Project.
“This puts us into the construction phase,” Sam Winder, project manager for Isabella Lake DSMP said. “We are excited to move from design to actually start building something and mitigating risk at Isabella Lake Dam.”
Groundbreaking for the new facilities in Kernville is expected to take place in October with construction to be complete by fall 2017.
Completed in 1953, Isabella Lake Dam is located approximately 42 miles northeast of Bakersfield. The reservoir is impounded by two earthen dams on the Kern River and Hot Springs Valley. Today, Isabella Lake and its dams reduce flood risk for Bakersfield and the surrounding region, and is a primary water source for water users throughout Kern County. The Isabella Lake Dam Safety Modification Project will address overtopping, seismic and seepage issues identified with Isabella Lake’s Main and Auxiliary dams to reduce the likelihood of dam failure. Construction of the dam modifications is scheduled to begin in 2017.

Cottage owners, homeowners and farmers around lakes Manitoba and St. Martin will be getting relief in the fall from the high water levels that have plagued their properties since the worst spring flooding in recorded history.
The Manitoba government announced it will start construction on an emergency channel out of Lake St. Martin immediately, and Lake Manitoba outflows through the Fairford River water control structure will be unrestricted throughout the winter, as recommended by independent engineering firms KGS and AECOM.
If construction can be completed by this fall, levels on both lakes would be lowered before spring run-off begins, reducing the likelihood of flooding in 2012.
Several different options were examined by KGS and AECOM with technical support from Manitoba Infrastructure and Transportation and Manitoba Water Stewardship. The option to quickly build an emergency channel that will allow for ongoing maximum flows through the Fairford River water control structure was assessed as the best option to provide emergency relief from high lake levels, and protect homes and communities along lakes Manitoba and St. Martin.
The assessment is based on data which includes site visits, topographic analysis, seismic bedrock investigation, aerial photography, LIDAR surveying and geotechnical work.
The Lake St. Martin emergency channel will go from Lake St. Martin to Big Buffalo Lake. The channel is expected to handle flows of up to 9,000 cubic feet per second (cfs), depending on lake levels when the channel becomes operational. From Big Buffalo Lake, the water will follow natural channels to the Dauphin River.
Both Lake Manitoba and Lake St.
Martin currently drain into Lake Winnipeg through the Dauphin River. This emergency channel is expected to affect Lake Winnipeg’s North Basin levels by less than one inch, which is approximately 0.5 per cent of Lake Winnipeg’s inflows. Lake Winnipeg levels are expected to drop by two feet before the Lake St. Martin channel becomes operational and Lake Winnipeg’s flood risk will not be affected by the operation of the channel.
The five-mile emergency channel is expected to be 300 feet wide and up to 25 feet deep. Details of the construction project are being finalized and consultation with the affected First Nations communities will continue as the project proceeds on an emergency basis.
It is expected to involve the excavation of as much as 2.5 million cubic metres of earth, 50 pieces of heavy equipment and 150 staff. Preliminary work has already started at the construction site.
Depending on progress of the construction of the emergency channel, additional construction of a bypass channel around the north side of the Fairford River water control structure will be undertaken to further reduce Lake Manitoba levels, as recommended by the engineering firms. This would also require expansion of the newly-built Lake St. Martin emergency channel to ensure no net addition of water to Lake St. Martin.
Manitoba Water Stewardship estimates building the emergency channel and maintaining maximum flows at the Fairford River water control structure all winter would bring the chance of Lake Manitoba staying below 814 feet in 2012 up to 90 per cent and Lake St. Martin’s chance of staying below 802 feet to 98 per cent.
Construction of a Fairford River bypass channel would increase the chance of Lake Manitoba staying below 814 feet in 2012 to 98.7 per cent.


Wimbleball Dam maintenance project
The joint maintenance project between South West Water and Wessex Water on Wimbleball dam is complete.
The work involved injecting grout into the bedrock to block fissures and prevent water ingress.
The project has been a success, with leakage through the dam reduced to historically low levels not seen since it was constructed.
This will help ensure the integrity of this vital and iconic structure for decades to come.
We would like to thank everyone for their patience during the works.

Quick Description: The Three Gorge Dam aims to rise the water level to 175m.
Date Posted: 10/28/2008 5:23:24 AM
Waymark Code: WM51ZW
The dam is the largest hydro-electric power station in the world. The total electric generating capacity of the dam will reach 22,500 MW
As with many dams, there is a debate over costs and benefits. Although there are economic benefits such as flood control, clean hydroelectricity and navigation, there are also concerns about the relocation of people, siltation, loss of archaeological and cultural sites and the impact on regional ecosystem.
When the water level is maximum at 175 metres (574 ft) over sea level (91 metres (299 ft) above river level), the reservoir created by the Three Gorges Dam is about 660 kilometres (410 mi) in length and 1.12 kilometres (0.70 mi) in width on average, and contains 39.3 cu km (9.43 cubic miles) of water.The total surface area of the reservoir is 1045 km². The reservoir will flood a total area of 632 km² of land compared to the 1,350 km² of reservoir created by the Itaipu Dam. The Three Gorges Dam reservoir is longer than the 560 kilometres (348 mi) length of Lake Superior, but only 1.1 % of the surface area of the lake (82,400 km²) and about 1/700 of the volume of the lake (28700 cu km).
The dam will raise the water level the third time to its designed maximum water level (175 m above sea level) by the end of 2008

LEE COUNTY, Fla. -- More water from Lake Okeechobee will begin pouring into Southwest Florida starting Friday.
The U.S. Army Corps of Engineers says it's increasing water release flows from the lake for the second straight week. The Corps says the lake's water level has risen about a quarter of a foot since last week, forcing them to dump more water into the Caloosahatchee River to ease the pressure on the aging Hoover Dike.
Beginning Friday, the Corps will increase flows into the Caloosahatchee with a target of 4,000 cubic feet per second (cfs) measured at Moore Haven Lock & Dam. The previous target rate was 2,800 cfs.
The new target flow for the St. Lucie River is now 1,800 cfs measured at St. Lucie Lock & Dam near Stuart. Its previous rate was set at 1,170 cfs.
Large water releases earlier this year hurt Southwest Florida's water quality and turned much of the water around Fort Myers Beach and Sanibel a brownish color.

ISLAMABAD: The first unit of strategically important 969 MW Neelum Jhelum Hydropower Project, located in Azad Jammu and Kashmir, will be inaugurated on Friday.
Prime Minister Shahid Khaqan Abbasi will inaugurate the first unit which will generate 242 MW electricity. The first unit will be followed by the second, third and fourth units at one month intervals respectively. Water filling in head race tunnel had already been commenced, followed by wet commissioning test in order to start generation.
The head race tunnel is a component of 52 kilometer long water way system of the project that has been constructed underground in the high mountain areas to divert water from the water reservoir to the power house of the project.
The project will provide about five billion low-cost hydel electricity to the national grid every year. Annual benefits of the project have been estimated at Rs 50 billion. Neelum Jhelum Hydropower Project is an engineering marvel with 90% of the project being underground in the high mountain areas.
Neelum Jhelum Hydropower Project consists of three main components i.e. a dam, waterway system comprising 52 km long tunnels and an underground power house.
The project has four units with installed capacity of 969 MW. Following electricity generation from Golen Gol Hydropower Project in January and Tarbela 4th Extension Hydropower Project in February this year, the third hydropower project of WAPDA i.e. Neelum Jhelum is also going to start electricity generation during the next month.
For optimal utilization of water and hydropower resources in the country, WAPDA has been implementing a two-pronged strategy for the purpose. Under the strategy, not only the under-construction projects are being completed in the shortest possible time, but the new projects are also being initiated in both water and hydropower sectors.


The prime minister has recently dedicated to the nation the 110-MW Pare Hydroelectric Plant. The Pare H.E. Project is situated in the Papum Pare District of Arunachal Pradesh. NEEPCO has taken up this Project to harness the Hydropower potential of the river Dikrong which is a tributary of river Brahmaputra and also utilize the Tail race discharge of the 405 MW Ranganadi H.E. Project stage. The project is a run of the river scheme. The project will have a 63 m High Concrete Gravity Dam and 2.818 Km long Head Race Tunnel (HRT). The installed capacity of the Project is 110 MW and the catchment area of the Project is 824 Sq. Km with design head of about 67.36m.

The Australian Government has made a commitment of $39.7 million to the project. The total cost of the project is still to be confirmed through the finalisation of the Business Case process.
Australian Government funding is provided through the National Water Grid Fund.
The project is currently in the planning stage. The Southern Forest Irrigation Scheme business case is currently underway.


In North Dakota Enbridge has proposed the Beaver Lodge Loop Project, which will involve the construction of a 12 or 16 inch diameter looping pipeline along the existing Enbridge North Dakota System from the existing Beaver Lodge Station near Tioga to Berthold. The looping pipeline is expected to increase the capacity along the 72 km segment to approximately 315,000 bbl/d of oil.
Tankage and new pump stations will also be constructed and the pipeline project will be undertaken by Enbridge Pipelines (North Dakota) LLC a subsidiary of Enbridge Energy Partners. The project is expected to be completed by the first quarter 2013.
The SORTI and Dunn projects will consist of the construction of a new 8 or 10 inch gathering pipeline system to expand the Enbridge North Dakota System, starting approximately 72 km south of its Beaver Lodge Station.
The project also consists of two new stations and the associated work to prepare for two new truck facilities. One new station will be located near Keene, North Dakota, and the second, Croff Station, will be located near the Dunn/McKenzie County border.
The proposed expansion of Line 26/EX-02, including added facilities in North Dakota, Saskatchewan, and Manitoba, will include an expansion of the US portion of the Portal Link (Line 26) by EEP, and the construction of two new pumping stations and enhancements of the pipeline north of Berthold.
The Canadian portion of the Portal Link (Line EX-02) will be extended with the construction of a new 121 km, 16 inch diameter pipeline from Steelman, Saskatchewan, to the Enbridge terminal at Cromer, Manitoba.


The Project consists of the design, construction, operation and heavy maintenance of 29 automated navigation dams and was justified by the necessity to replace the former obsolete and dangerous to operate manual dams on the Aisne and Meuse rivers (northeast of France). The Project also includes the operation of two pre-existing dams, which have been modernised, and the operation of four micro-hydropower plants with a total capacity of 4.6 MW.
The new dams prevent flooding, regulate water flow, and produce electricity, to the benefit of the users of the rivers (navigation, irrigation, industry, fish farms) and the population living on the banks (protection against flooding, water reserves).

Liaoning Water Conservancy and Hydropower Survey and Design Research Institute Co., Ltd. / Dongtaizi Reservoir Project
Liaoning Water Conservancy and Hydropower Survey and Design Research Institute was responsible for delivering the engineering design of the Dongtaizi Reservoir. This project is one of 172 major water conservancy endeavors meant to tackle China’s water scarcity and flood risk issues sponsored by the Chinese government. The proposed infrastructure is a rockfill dam with an asphalt core wall and a concrete gravity dam with a total storage capacity of 321 million cubic meters. Located in the upper and middle reaches of the Xar Moron River in Chifeng, Inner Mongolia, the reservoir will mitigate severe flood risk in the lower reaches of the river and supply water and agricultural irrigation to the areas adjacent to bottom of the river basin.
- The Dongtaizi Reservoir Project is one of 172 major water conservancy projects in China and one of 12 key livelihood projects in Inner Mongolia meant to mitigate severe flood risk and combat water scarcity.
- Complex terrain and infrastructure design required 3D modeling solutions to quantify structural elements and excavation amounts.
- Using BIM applications reduced design error by 90%, avoiding design changes and rework during construction.
“The use of Bentley software has solved the important and difficult problems in the engineering design of Dongtaizi Reservoir, provided strong endorsement for designers, improved the design efficiency of our institute, reduced design errors, and made the digital transfer of design results possible.”
– Wang Yixin, Director of the Digital and Smart Engineering R&D Center, Liaoning Water Conservancy and Hydropower Survey and Design Research Institute Co., Ltd.
After considering their options, the team employed Bentley’s BIM software for accurate 3D design. Liaoning Water integrated OpenBuildings and OpenRoads Designer to streamline collaboration among multiple engineering disciplines and to manage data. They surveyed the landscape and created a detailed 3D geological model to precisely calculate excavation volumes and plan excavation processes. This visualization in OpenRoads also allowed the project team to accurately position the ecological fishway and connect the structure’s complicated spatial curve to the landscape. The rockfill dam section was designed using OpenRoads’ linear engineering capabilities to generate a truthful 3D model incorporating all control and boundary conditions. Several engineering disciplines collaborated on the design of the concrete dam in OpenBuildings, allowing the hydraulic machinery, metal structure, and electromechanical equipment to be designed to avoid collisions.
By using Bentley applications, Liaoning Water reduced design error by 90%. Delivering a technologically advanced model minimized changes to the overall design during construction. Accurately calculating project cost in the design stage of the project decreased the government’s overall investment. With the support of open modeling technology, the project team improved design efficiency by 40% to deliver the plans two weeks ahead of schedule. They leveraged BIM software to produce a digital twin that provides full lifecycle support of the dam, including management during construction, operations, and maintenance. Using this project as the foundation for BIM usage on future water conservancy projects, Liaoning Water has implemented corporate 3D collaborative design standards and trained personnel to become a regional leader in BIM application.
OpenRoads was used to successfully create a complex model of the dam excavation body, and at the same time get the back-filling quantities of excavation by analyzing earthwork from the original terrain and the excavated terrain. This was more intuitive, productive, and accurate compared with traditional 3D engineering.
OpenBuildings helped enable modeling of the concrete dam, as well as employ collision detection. In addition, OpenBuildings enabled quantity statistics of building elements and hydraulic components, eliminating the difficulty of accurate results faced in traditional engineering.

Many dam structures in Australia were designed and built in the 1950s and 60s with limited hydrological information. As a result existing spillway structures are under-sized for today’s revised probable maximum floods (PMF). Potential problems such as the generation of excessive negative pressure over spillway crest under increased flood condition could be encountered. This may cause instability or cavitation damage to the spillway. The raised flow profile may also have adverse impacts on crest bridges and gate structures.
Historically, physical models have been constructed in hydraulic laboratories to study these behaviours, but they are expensive, time-consuming and there are many difficulties associated with scaling effects. Today, with the use of high-performance computers and more efficient computational fluid dynamics (CFD) codes, the behaviour of hydraulic structures can be investigated numerically in reasonable time and expense.
This paper describes the two- and three-dimensional CFD modelling of spillway behaviour under rising flood levels. The results have been validated against published data and good agreement was obtained. The technique has been applied to investigate several spillway structures in Australia.

Tank Hill Reservoir is located approximately 25km north-east of Warrnambool and forms part of the fresh water supply for the town. It was built in the 1930’s by the construction of an earthfill dam across the natural breach of the crater of an extinct volcano. The reservoir is an offline storage with a small natural catchment and has a nominal capacity of 770ML at Full Supply Level (FSL). The reservoir is operated by South West Water Authority (SWWA).
Previous investigations had identified instability issues associated with the dam embankment and the necessity for remedial work to increase the stability of the dam embankment. SKM undertook detailed survey and investigations and the proposed upgrade works include the construction of a downstream stabilising berm incorporating graded filters and a drainage system. The condition of the outlet works was investigated as part of the project, with some of these works found to be in poor condition with a risk to the security of supply, necessitating the design of refurbishment of the outlet works. The degree of siltation of the reservoir was also assessed, and some loss of capacity due to siltation was noted.
Detailed investigations were performed to determine the optimum configuration of the stabilising berm and to locate and test suitable construction materials. The embankment interface filters were designed to satisfy modern filter design criteria and were incorporated in the embankment drainage system. The condition of the outlet works, including the intake standpipe, three offtake valves and the outlet conduit beneath the embankment, were assessed via manual and CCTV inspections. An operation review, incorporating the proposed upgrade works within the framework of ongoing operation of the reservoir for supply to downstream customers was also prepared, as was a construction risk assessment.
This paper will present “extremely useful practical information” for dam design engineers, owners and operators where the whole spectrum of dam safety issues is required for the successful completion of remedial works design and construction.
Hydro Tasmania has recently developed a Dam Safety Emergency Plan, which covers 54 referable dams throughout Tasmania. A major contribution was the development of the Pieman River flood warning system. The flood warning system is a computer-based model that forecasts the hydrological situation of the catchment up to 48 hours into the future and alarms the appropriate personnel when a flood event is imminent. The Pieman River catchment experiences some of the highest average annual rainfalls in Tasmania and contains dams in the High Hazard category. The flood warning system was developed using Hydstra Modelling™ (formerly TimeStudio), which links directly to the Hydstra TSM™ database. This package offers powerful automation tools that enable the Pieman River flood warning system to operate, alert personnel and display results on Hydro Tasmania’s internal website with no manual involvement. With its maintenance free operation and user-friendly interfaces, the Pieman River flood warning system is an effective contribution towards the overall risk management package of the Pieman River Power Development
This paper discusses reliability issues of the fourteen 3.85m high by 7.89m wide radial gates at Glenmaggie Dam in Victoria and the twin 3.6m high by 16.5m wide drum gates at Little Nerang Dam in Queensland. The Glenmaggie dam radial gates are manually controlled using electrically driven (mains and diesel generator power supply) hoist motors with a petrol driven hydraulic pack for use in the event of complete electrical power supply failure. A detailed fault tree analysis was developed for the spillway gate reliability of the Glenmaggie Dam gates as part of the risk assessment for the dam, which was being completed at the time of publishing the paper. Each of the identified components of the spillway gates, including human error in operation was used to evaluate the probability of failure of a single gate or multiple gates for inclusion in the event tree to estimate the risk and assist the evaluation of the requirement for remedial works. The Little Nerang drum gates are fully automatic hydraulically operated gates with independent operating mechanics and a common override system in the event of automatic system failure. Drum gates are uncommon on dams and the system operation is discussed together with an assessment of the reliability and measures taken for handling operating risks during floods for the dam, which has some stability concerns.
South East Queensland Water Corporation (SEQWater) as owner and operator is proceeding with an upgrade of the flood capacity of Wivenhoe Dam. SEQWater has formed an Alliance with Leighton Contractors, Coffey Geosciences, Montgomery Watson Harza (MWH) and the Department of Commerce-NSW (formerly DPWS, NSW) to upgrade Wivenhoe Dam. This paper presents feasibility level investigation and design activities for an upgrade option, comprising a large labyrinth auxiliary spillway at the right abutment of the dam, for supplementing the existing gated spillway in handling the Probable Maximum Flood (PMF) event. This right abutment auxiliary spillway option incorporates Hydroplus type concrete fuse gates. The investigation so far has proved the technical viability of this option, however, ranking along with the other three options against various criteria will lead to the selection of the preferred upgrade option.


The Ocoee River release schedule provides water for hydroelectric power production and recreational water releases for us to enjoy the river.
2019 Middle Ocoee River Rafting Calendar:
2019 Upper Ocoee River Rafting Calendar:
There are 3 dams on the Ocoee River that were built to help provide hydroelectric power for the surrounding areas.
Ocoee River Dam #1 was completed in 1911 and is best known for being the Lake Ocoee watershed. Also known as Parksville Lake, this lake is a great place to swim and boat. There are also beaches and picnic areas alongside the lake.
Ocoee River Dam #2 was completed two years later in 1913. This section is known as the Middle Ocoee River. This 30 foot dam funnels water through the historic wooden flume line to produce hydroelectric power. Dam #2 also provides regular water releases during the summer months giving white water lovers great Class III & IV white water to enjoy.
Ocoee River Dam #3 was built to help supply power for the WWII war effort and completed in 1942. This dam diverts water through a tunnel system carved in the mountains. Ocoee Dam #3 supplied water for the Ocoee White Water Course used in the 1996 Olympic Games. This world class white water is still rafted on the Upper Ocoee River during the summer.
Carolina Ocoee provides rafting trips on the Middle Ocoee section that is fed by Dam #2 and the Upper Ocoee section that is fed by Dam #3. The Ocoee River Rafting Release Schedule allows Outfitters and whitewater adventurers to have regular water releases and consistent flows. The Ocoee River is open for rafting March through October.

Sewage pumps are one of the most popular types of fluid machinery in municipal, industrial, and environmental engineering and many other fields. The influence of tip clearance size on the pump performance and internal flow field distribution within a sewage pump was investigated in this study based on numerical calculation and test verification. Three models with different tip clearances were obtained by adjusting the assembly structure and simulated by the computational fluid dynamics software to solve the Navier–Stokes equations for three-dimensional steady flow. The accuracy of numerical methods was verified by comparison with the experimental results. The sewage pump performance under different tip clearances was then compared and analyzed. The structure and propagation of the vortices inside the impeller caused by the leakage flow with different tip gaps were also analyzed. The leakage flow in the impeller couples with the cover reflection and secondary flows, forming different vortex structures in various locations of the impeller channel. These vortex structures cause large hydraulic losses near the blade suction surfaces. This finding could provide useful insights for the improvement of the hydraulic performance and operational stability of semi-open sewage pumps.

Evaluation of measures to increase the discharge capacity of the Limmat by 2D simulation.
If the Sihl has high tide, the city of Zurich is at risk of flooding. As a long-term solution, the canton of Zurich is planning a flood relief tunnel for the Sihl (Langnau am Albis) into the Lake Zurich near Thalwil. In case of a flood, the high water peaks can thus be directed into the Lake Zurich . Without appropriate countermeasures, the water level at Lake Zurich would increase. As part of investigations in 2014, it was found out that the Rathausbrücke and then the Münsterbrücke limit the discharge capacities of the Limmat . To compensate an increase of the water level of Lake Zurich, the discharge capacity of the Limmat is increased by targeted measures on the Limmat bridges (Munster- and Rathausbrucke).
To evaluate the influence of the planned measures on the discharge capacities of the Limmat bridges, the measures are integrated in the current 2D model and the discharges for certain high water levels of Lake Zurich are defined. Measures to increase the capacity are especially lowering of the bed and the optimization of the bridge piers on the Rathausbrucke, which is part of the project "Replacement Rathausbrucke" of the city of Zurich.

Construction work has started on the four-year, $416M Calaveras Dam replacement project, which forms part of the San Francisco Public Utilities Commission’s (SFPUC) $4.6B Water System Improvement Program (WSIP) to repair, replace, and seismically upgrade the aging pipelines, tunnels and reservoirs in the Hetch Hetchy Regional Water System.
Representatives from SFPUC, together with local and state officials, broke ground on construction to replace the existing Calaveras Dam in unincorporated Alameda County on Friday.
The Calaveras Dam – originally built in 1925 – is part of the Hetch Hetchy Regional Water System that provides drinking water to 2.5 million people in Alameda, Santa Clara, San Mateo and San Francisco counties. Since 2001, after Calaveras Dam was deemed seismically unsafe by the California Division of Safety of Dams, water levels in the reservoir have remained at 40% of full capacity. The Calaveras Dam Replacement Project will allow the water levels back to the historic capacity of 31 billion gallons.
The replacement project will replace the existing dam with a 220ft high new seismically-designed earth and rock-fill dam that will be constructed right next to the existing one. The existing dam will be left in place and fully submerged underwater when the project is complete. Approximately 7 million cubic yards of material will be excavated to construct the new dam.
The ground-breaking ceremony highlighted the key features of the project including: a new spillway that will be 1550ft-long utilizing 40,000-cubic-yards of concrete, the installation of fish passage screens and a fish ladder at the Alameda Creek Diversion Dam to support the restoration of Steelhead to the Alameda Creek Watershed, construction of a new intake/outlet tower consisting of a 20ft-diameter by 163ft-deep vertical shaft and three new tunnels to convey water to and from the reservoir.
The contract for construction was awarded to a JV of Dragados USA, Flatiron West and Sukut Construction. Major construction is anticipated to be complete in 2015.
The Calaveras Dam Replacement Project is the 71st of the total 81 projects in the WSIP to begin construction. The WSIP is approximately 50% complete.

Stefanutti Stocks Pipelines constructed a 43km-long, 950mm diameter steel pipeline for Platmin South Africa (Pty) Ltd. The pipeline runs between the Vaalkop Dam (to the east of Pilanesburg Game Reserve) to within four kilometres of the Limpopo Province town of Northam. The
project’s objective is to purify and pump an extra 70-million litres of water per day through the new and existing systems to clients at different locations. The new pipeline runs parallel to two already existing pipelines.
The project was split into 23km of rising main pipeline, and 20km of gravity main pipeline.
The rising main, a 950mm-diameter steel pipe, runs from the Vaalkop Dam water purification plant to the reservoirs at La Patrie. Other work on this phase included the construction and installation of 36 air valve chambers, 11 scour valve chambers and seven valve chambers; the construction of two road crossings; two Eskom power line crossings and the tie-in of pipework at the Evergreen Junction, which is the take-off to Sun City.
The gravity main runs from the reservoirs at La Patrie to Padda Junction, four kilometres from Northam. Other work on this phase included the installation of valves and valve chambers; construction of two road crossings; one railway crossing using the pipe jacking method of installation; one Eskom powerline crossing and the tie-in of pipework at Padda Junction.


Wu-Hao-Gou pump station is one of many pump stations being going to build in order to meet the increasing need of water supply in the Shanghai city. Owing to limited building site, large discharge and multi water outlet direction, the design and arrangement of hydraulic structure become more difficult than usual pump station. In the paper, CFD method is used to simulate the whole inlet flow field and improve hydraulic performance of the pump station. Firstly, the whole hydraulic structure geometric model, combined by Penstock, transition passage, diversion channel, fore bay, suction bay and suction pipe, is built and subdivided with unstructured mesh. Secondly, inlet flow field of the original pump station scheme is simulated and analyzed with the SIMPLEC algorithm, the realizable k-ε turbulence model and the symmetric boundary hypothesis on the free surface. Thirdly, the better scheme is calculated with the same numerical method after taking some effective measurements. Lastly, the better scheme is simulated with the VOF model, as well as the numerical results are compared with the above symmetric boundary hypothesis model to reveal the fact that the main flow character is similar but some flow details differ between the two free surface model. Then, the physical model experiment will be performed to verify the better scheme in the next step.

The Roland Avenue Project replaced two existing low water crossings with bridges to provide unflooded access during a 1% annual chance (100-year) storm event. CEC developed updated drainage models to analyze the existing and proposed conditions, which resulted in correcting the floodplain maps. CEC prepared a Conditional Letter of Map Revision and prepared 454 notification letters to property owners affected by the changes in water surface elevation.
Also, CEC designed approximately 3,248 LF of new 12” water line to provide connectivity between two dead-end mains located at the project ends. At the bridges, the new water main was installed through the abutment wall and mounted between I-beams to protect from potential damage by debris. Sewer design included relocation of 80 LF of gravity sewer main, and the construction of a new double barrel sewer siphon consisting of 1,200 LF of KDPE that crossed under the Salado Creek.

Ethiopia assigned Kifle Horo (Engineer) as the new project manager of the Grand Ethiopian Renaissance Dam (GERD). After the death of Simegnew Bekelle (Engineer), Ephrem Weldekidan (Engineer) led the project as a manager. Now, he is appointed to serve as a deputy project manager together with Fikadu Kebede.
Before joining the project of GERD, Kifle had served at Ethiopian Electric Power as power sector consultant and advisor for project management.
GERD is located approximately 500 km north west of the capital Addis Ababa, in the region of Benishangul - Gumuz along the Blue Nile. At the end of the works, the Grand Ethiopian Renaissance Dam will be the largest dam in Africa: 1,800 m long, 155 m high and with a total volume of 74,000 million m³.
The project involves the construction of a main dam in Roller Compacted Concrete (RCC), with 2 power stations installed at the foot of the dam. The power stations are positioned on the right and left banks of the river and comprise 16 Francis turbines with a total installed power of 6,000 MW and estimated production of 15,000 GWh per year. The project is completed by a 15,000 m3/s capacity concrete spillway and a rockfill saddle dam 5 km long and 50m high, both located on the left bank.

Home » Shop » 2010 – Performance of Taum Sauk Upper Reservoir Dam During Reservoir Refill
Jared Deible, John Osterle, Charles Weatherford, Tom Hollenkamp, Matt Frerking
The original rockfill dike, constructed in 1963 to form the Upper Reservoir at the Taum Sauk Pump Storage Project near Lesterville, MO failed on December 14, 2005. The Upper Reservoir has been completely rebuilt as a 2.83 million cubic yard (2.16 million cubic meters) Roller Compacted Concrete (RCC) Dam in compliance with FERC Regulations. The project is the largest RCC project constructed in the USA and is the first pumped storage project to utilize an RCC water retaining structure. The project is owned and operated by AmerenUE and consists of an Upper Reservoir and a Lower Reservoir connected by a vertical shaft, rock tunnel, and penstock. The Powerhouse has two pump-turbines with a total generation capacity of 450MW.
A refill plan was developed to monitor the performance of the dam during the first refill. Because it is a pumped storage project with no natural inflow, the reservoir level can be raised and lowered with reversible pump turbines. The refill plan includes hold points when the dam s performance will be assessed at eight reservoir levels. Monitoring of the performance of the dam is done through instrumentation readings and visual inspections. Inspections check for alignment changes, leakage, seepage, cracking, or any other unusual or changed conditions. Instrumentation monitored during the refill program includes piezometers, seepage weirs, survey monuments, and joint meters. The level control system for the project was also evaluated during the refill program. This paper summarizes the monitoring and inspections conducted during the refill and the performance of the dam during this period, and the performance of the dam during the initial period after the refill program.
ANCOLD is an incorporated voluntary association of organisations and individual professionals with an interest in dams in Australia.


The project includes replacement of the existing 12” main pipeline with a new 40” main pipeline to meet the future needs. The new pipeline is 2.0 km in length and will follow the main Silwan Road.

Location: Watershed Physical Processes Research2012 Annual Report
1a. Objectives (from AD-416):
Develop an algorithm to link the channel evolution computer model CONCEPTS to two-dimensional flow and sediment transport models of overbank flow that allows for improved prediction of sediment exchange between stream and floodplain; and 2) Evaluate the resulting modeling system for selected streams in the Piedmont or Coastal Plain Physiographic Provinces and the Lake Tahoe Basin.
1b. Approach (from AD-416):
An improved modeling system for inbank and overbank sediment transport will be developed by coupling the one-dimensional (1D) ARS channel evolution model CONCEPTS to a two-dimensional (2D) model of flow and sediment transport. The two-dimensional model will be stacked on top of the one-dimensional model. Formulations will be developed that relate the vertical flux of water and sediment particles between 1D and 2D models as a function of flow and sediment concentration in the inbank and overbank sections of the stream channel. The enhanced modeling system will be utilized to evaluate the water quality benefits of water-retention measures on floodplains.
3. Progress Report:
We completed the comparison of various two-dimensional (2D) computer models of river morphology to be coupled with the one-dimensional (1D) channel evolution computer model CONCEPTS. We selected the TELEMAC2D model because: (a) it uses a flexible mesh structure that can accurately represent diverse channel and floodplain topographies; (b) it uses a similar method to advance the solution in time as CONCEPTS; (c) it is coded in the same programming language (Fortran) as CONCEPTS; and (d) it is widely used and supported. We completed the derivation of the mass and momentum fluxes required to couple the 1D and 2D models.


Krom River or Kromme River (Afrikaans: Krommerivier) is a river in the Eastern Cape Province in South Africa. The river flows into the Indian Ocean through an estuary on the north side of St Francis Bay, west of Port Elizabeth. The Krom river flows in an ESE direction and is approximately 109 km long with a catchment area of 1,085 km2.
The Churchill Dam and the Impofu Dam are dams on the Krom River. The latter is located near Humansdorp. Presently this river is part of the Fish to Tsitsikama Water Management Area.


It is a river flow diversion project of the west flowing Yettinahole, a vital tributary of the Netravathi, through eight diversion weirs and a canal network spanning 1,000 kilometres.
The water will be pumped from the weirs to a network of five delivery chambers and then channeled eastward through giant pipes that cut across the Western Ghats. In addition, seven storage reservoirs will be constructed in several districts of Karnataka.
. The project proposes to divert nearly 24 TMC (or 672 billion litres) of water from the head-waters of the Netravathi river towards the water-scarce districts of Kolar, Ramanagara, parts of Hassan, Tumkur, Chikkaballapur, Bengaluru Rural and Devanahalli Industrial Area, – besides augmenting water to T.G. Halli and Hesaraghatta reservoirs near Bengaluru city.
It is also called as Netravati River Diversion Project.
The Yettinahole project envisages the construction of eight dams and its impact on the flora and fauna may be to be negative.
The construction may affect the elephant corridor in the region.

KSEB decides to increase power generation in Idukki to reduce water level
The district administration issued a blue alert in the wake of the water level in the Idukki reservoir crossing 2,390.85 ft on Tuesday. With an increased spell of rainfall in the catchment areas, the water level was near to the blue alert level for the past two days.
The Kerala State Electricity Board (KSEB) sounded the blue alert with the water level reaching 2,391.18 ft in the morning. It was 86.41% of the storage level.
The blue alert level for the day as per the new rule curve level fixed by the Central Water Commission (CWC) was 2,390.85 ft. An orange alert will be issued before October 20 if the water level reaches 2,396.85 ft and a red alert at 2397.85 ft. The full reservoir level is 2,403 ft.
The present water level is higher than the level recorded on the same day in the previous two years. The change in monsoon pattern is also evident as the catchment area recorded above normal rainfall in the first and second week of October.
A power position meeting of the KSEB on Tuesday decided to increase generation from 5 mu to 10 mu at the Moolamattom powerhouse to reduce the water level in the reservoir.
The Idukki reservoir is mainly reserved for power generation when the demand in the State escalates during summer season. The generation which remained below normal was raised to 5 mu from 3.2 mu on Monday.
The KSEB wants to avoid a situation of opening the dam shutters as in the case of the 2018 floods and keep the water level below the new rule curve level. With the increased power generation, water level will fall in the coming days. The Dam Monitoring and Research Station is monitoring the situation, an official said.
The power position meeting also decided to surrender power from the Central pool and instead use the power generated at Moolamattom. The present situation does not warrant opening of the dam shutters as the water level remained over 10 ft short of the FRL level. The shutters need to be raised only if there is extremely high rainfall in the coming days, the possibility of which is remote considering the weather predictions, the official said.

For flood control management, the Bureau of Reclamation increased Shasta Dam releases Friday by 20,000 cubic feet per second, bringing the total releases from the dam to 40,000 cfs into the Sacramento River.
The increased releases are necessary to meet flood space regulatory requirements within the reservoir and will remain at that rate until further notice.
Folsom Dam on the American River will gradually reduce releases on Monday and Tuesday, from 20,000 cfs to 15,000 cfs. Folsom Dam is about 25 miles east of Sacramento.
People recreating in or along the Sacramento river should take appropriate safety precautions during periods of high river flows.
Daily information on expected flows in California rivers can be found on the California Data Exchange Center website at cdec.water.ca.gov./cgi-progs/getAll?sens_num=23 or on the U.S. Army Corps of Engineers website at www.spkwc.usace.army.mil/generic/rel_rep_s.html.

When completed, the Mohale Dam will form the main storage element in Phase 1B of the
LHWP and will be located on the Senqunyane River immediately downstream of the confluence
with the Jorodane River.
The dam will be approximately 144 m high with a total capacity of 938 million m3.
The catchment area for the dam is 938 km2 with an MAR in the order of 312
million m3 with the result that it is a 3 MAR dam.
Various options were considered for the Mohale Dam including rockfill, concrete arch
and Roller Compacted Concrete (RCC). After thorough investigations it was decided to
construct a concrete faced rockfill dam (CFRD)and with a height of 145 m, the Mohale Dam
will be one of the top ten highest dams of its type in the world. One of the
considerations leading to the selection of the CFRD is the fact that such dams are very
stable when earthquakes or seismic activity are experienced as can be the case in Lesotho.
The rockfill construction will also make good use of the basalt materials which are
readily available in the surrounding Lesotho mountains. The CFRD is also less prone to
time delay risks such as adverse weather conditions and the design is therefore better
suited to the tight 5-year construction programme. The dam is scheduled to deliver water
to Katse Dam in the year 2003 and must be able to impound the
water two years earlier in 2001.
The dam will require approximately 7 million m3 of rockfill material and in
order to achieve the programme goals of impoundment by the year 2001, the thin concrete
face on the dam wall will be constructed in two phases. Instead of casting the concrete
face once the dam reaches the full height, an interesting design feature of the Mohale dam
is the placement of a portion of the face once the dam is approximately two thirds of the
final height. As the lower slab is being placed, construction on the upper third will
continue with the result that the dam will be able to impound water at least one year
earlier than would otherwise have been the case.
Foundation excavation to form the base of the dam is expected to be limited and a
geotechnical investigation is currently underway to confirm the foundation conditions.
Further investigations are also underway to source the 7 million m3 of basalt
for the dam wall as well as to find suitable aggregate for the 100 000 m3 of
concrete needed for the face of the dam wall. A fleet of 50 large trucks will be needed to
haul the enormous amount of rockfill up the steep roads which have yet to be blasted into
the Senqunyane Valley. The haul roads and quarries will be located below full supply level
whenever possible to minimise the environmental impact of the construction on the
The intake structure for the Mohale - Katse transfer tunnel will be located
approximately 5 km upstream of the dam wall. With a minimum operating level of 2005 m
above sea level, the Mohale reservoir will have an active storage of 856 million m3.
The spillway of the dam, located on the left flank will be an ogee type with a concrete
lined chute and a flip bucket at the bottom with a design capacity of 2 600 m3/s.
Preliminary estimates for the dam put the cost at between $135 million and $225 million
at 1997 prices and exchange rates. These estimates do not include finance charges.

Dr Kusdianto ST., M.Sc.Eng.
Single phase turbulent flow in a vessel agitated by side entering inclined blade turbine has simulated using CFD. The aim of this work is to identify the hydrodynamic characteristics of a model vessel, which geometrical configuration is adopted at industrial scale. The laboratory scale model vessel is a flat bottomed cylindrical tank agitated by side entering 4-blade inclined blade turbine with impeller rotational speed N= 100-400 rpm. The effect of the impeller diameter on fluid flow pattern has been investigated. The fluid flow patterns in a vessel is essentially characterized by the phenomena of macro-instabilities, ie the flow patterns change with large scale in space and low frequency. The intensity of fluid flow in the tank increase with the increase of impeller rotational speed from 100, 200, 300, and 400 rpm. It was accompanied by shifting the position of the core of circulation flow away from impeller discharge streamÂ …
