MHPA’s headrace tunnel nearing completionSurjaman Thapa, Trongsa
Mar 20 2017
The construction of the headrace tunnel of Mangdechhu Hydroelectric Project Authority (MHPA) in Trongsa will be complete, this June.
Currently two phases of the construction have been complete, and the third and final phase is underway. Under third phase, additional 500 metres of tunnel has to be constructed. After that, the headrace tunnel will be operational.
The economic affairs minister, Lekey Dorji and the Indian Ambassador Jaideep Sarkar, attended the completion ceremony of the two phases of headrace tunnel construction in Trongsa, today.
MHPA officials highlighted that despite encountering with several geological hurdles, the two phases of excavation of headrace tunnel (measuring 13 kms in length) were finally complete.
Headrace tunnel is the key component of the hydropower project and it will divert the river from the dam to the powerhouse to run the turbines.
“Mangdechhu Project will be complete within seven years’ time and it is becoming an exemplary project in the SAARC region,” said the MHPA’s Managing Director, A.K.Mishra.
The economic affairs minister, Lekey Dorji, said at the moment, only five percent of the total hydropower energy is harnessed in the country.
However minister added, with the commissioning of few additional projects, more energy can be harnessed. The projects are: Punatsangchhu 1 and 2, Mangdechhu, and Kholongchhu.
The execution works of 720-megawatt Mangdechhu Hydropower Project began in 2011. The cost of the project is Nu 40, 206 M and is expected to be complete by this July.
Once commissioned, the hydroelectric project could be earning gross revenue of Nu 7 billion annually. This is assuming electricity from the project is sold at Nu 2.5 a unit.

Concrete pour has commenced for construction of the core dam at the Rogun hydropower project in Tajikistan, WeBuild has announced, marking a major milestone for what will be the world’s highest dam once complete.
Webuild CEO Pietro Salini joined Tajikistan President Emomali Rahmon at a ceremony to celebrate this achievement on 15 July.
Located in the upper reaches of the Vakhsh River in the Pamir Mountains west of the Himalayas, the 3600MW Rogun hydropower project will double the Central Asian country’s production capacity once complete. The project will feature the highest dam in the world with a dam crest at 1300 m asl, breaking the record held by the Nurek Dam, also in Tajikistan. At 335m, Rogun will also be the tallest dam in the world.
Rogun already has two turbines that are producing electricity. Unit 5 and 6 each have a capacity of 600MW. The early generation has allowed Tajikistan to reduce power shortages suffered during the winter months, and export part of the electricity produced to neighbouring countries.
Commissioned by OJSC Rogun Hydropower Plant, Webuild is responsible for the main civil works in the construction of the rockfill dam with a loam core.

The Lesotho Highlands Development Authority (LHDA) has launched a tender for the Polihali Dam, marking an important milestone for Phase II of the Lesotho Highlands Water Project.
The tender is the start of procurement for the second main works construction tender and follows on the May tender for the construction of the Polihali Transfer Tunnel.
The Polihali Dam will be a concrete faced rockfill dam (CFRD) similar to the Mohale Dam, which was built during Phase I of the Lesotho Highlands Water Project (LHWP).
The embankment will stand approximately 166m high, have a crest length of about 920m and a crest width of 9m. Over 14 million cubic metres of rock which will be quarried locally within the dam basin will be compacted to form the embankment.
The dam will create a reservoir on the Senqu and Khubelu rivers with an estimated surface area of 5053 hectares and a full supply storage capacity of 2325 million cubic metres. The Polihali Dam infrastructure also includes a 43m high, 600m crest-length CFRD saddle dam, a spillway and a compensation outlet.
The flow from Polihali will increase the volume of water to be transferred from the Katse Dam, the centre point of the Lesotho Highlands Water Project which was constructed during Phase I.
The current water transfer volumes to the Gauteng region of South Africa will incrementally increase from 780 to 1270 million cubic metres per year.
This will also simultaneously increase the energy generated by the Muela hydropower plant from approximately 500GWh to 800GWh per year, a further step in the process of securing an independent power supply to meet Lesotho’s domestic needs.
“The launching of the construction of the main works open tender is the culmination of years of planning and hard work of dedicated design and procurement teams,” said Tente Tente, CE of the LHDA. “Our objective with this final procurement stage is to attract suitably qualified companies with the capability, experience and resources to undertake the construction of the Polihali Dam within the set timeframes and to the required quality.”
Interested construction firms have up to 12 November 2021, to submit tenders. Specific information on the requirements and conditions of the tender is available on the LHDA website at http://www.lhda.org.ls/tenderbulletin/currentProcurement.aspx.
The Matla a Metsi Joint Venture which comprises Lesotho, South African and international experts: GIBB (Pty) Ltd; MPAMOT Africa (Pty) Ltd; Tractebel Engineering SA; LYMA Consulting Engineers of Lesotho, was awarded the Polihali Dam design and construction supervision contract in 2017.
The Polihali dam construction procurement is launched as construction activity on ten advance infrastructure contracts progresses steadily with some contracts expected to be completed in 2021. Construction of the 33kV line, which will provide a temporary power supply to the Polihali village, was completed in 2020.
Work on the 132kV line has advanced with the construction of access roads, 91 tower foundations and the erection of 84 towers out of a total of 93.
The Polihali and Katse civil works; access roads, pipe laying for potable water and sewerage lines have been completed, and construction on the main access roads is underway.
Excavation on the Polihali diversion tunnels is close to completion with breakthrough on both tunnels expected in the second half of August.
According to the current master programme, water delivery is scheduled for 2027/28. Timeous construction of the dam and transfer tunnel is critical to meeting the water delivery deadline of the project.
Phase II of the Lesotho Highlands Water Project builds on the successful completion of Phase I in 2003. It delivers water to the Gauteng region of South Africa and utilises the water delivery system to generate hydroelectricity in Lesotho.

Mar 27, 2017- There will be soon be an additional 7.6 MW of electricity in the national grid once construction of the Jogmai Khola Hydroelectricity Project finishes. Sanvi Energy, the developer of the hydropower plant has completed majority of the construction work and is planning to put the plant through testing process within two weeks.
The developer has already completed the construction of a 1.5 km-long tunnel. Similarly, construction of other infrastructure such as headwork, defender and transmission line has been completed. “Around 99 percent of the job is done and we have a little work to do on pipeline and outlet,” said Hari Babu Neupane, controller of the project. “We will complete it in 15 days and start test transmission before going for the commercial generation.”
The project will evacuate electricity generated in its powerhouse at Maijogmai to the substation at Godak via a 11 km-long transmission line built by the project that passes through Maghe, Hattitar, Maibeni and Bharabesi.
“We have completed the construction of the entire transmission line and we will soon start test generation and transmission,” said Neupane. Likewise, the 132 kv transmission line at Kabeli corridor will transmit the electricity from the Godak substation to the national grid.
The developer started the construction of the project in Jogmai River on November 2014 after constructing an access road that passes through Fikkal. Sanvi Energy spent around Rs 1.5 billion to complete the development of the project.
Once this hydropower project starts generating electricity, Ilam will have hydropower projects with a total installed capacity of 61 MW. Before Jogmai, other projects like the 29 MW Sanima Hydro, 6.2 MW Puwa Khola, 12 MW Upper Mai Khola, 4.5 Mai Khola, and 3 MW Upper Puwa Khola were generating electricity in the district.
Soon the installed capacity will reach 80 MW as other hydropower projects in the region are nearing their completion date. The construction of Upper Mai Khola cascade, Puwa Khola and Mai Khola has reached final stage.

Construction of Hatta's hydroelectric power plant is 58.48 per cent complete, authorities announced on Monday.
Dubai Electricity and Water Authority (Dewa) said construction of the 72m main Roller Compacted Concrete wall of the upper dam and the concrete lining of the water tunnel is complete.
Saeed Mohammed Al Tayer, managing director and chief executive of Dewa, visited the power plant site to check progress on the project.
He inspected the progress made on the water tunnel, which is 1.2km long and connects the two dams.
He also visited the power generators site and the upper dam.
The station will have a production capacity of 250 megawatts, a storage capacity of 1,500 megawatt hours and a lifespan of up to 80 years.
It will be the first of its kind in the GCC, built with an investment of Dh1.421 billion ($387 million). The project is planned for completion in the fourth quarter of 2024.
The plant will help achieve the Dubai Clean Energy Strategy 2050 and the Dubai Net Zero Carbon Emissions Strategy 2050 to provide 100 per cent of Dubai’s total power production capacity from clean energy sources by 2050.
These include different technologies such as solar photovoltaic panels, concentrated solar power, and green hydrogen production using renewable energy.
The project will also support the plan to develop Hatta and meet its social, economic, developmental and environmental needs, as well as provide job opportunities for Emiratis in the area.
To function, water stored in the upper dam will flow through the underground tunnel, rotating turbines. The mechanical energy from the rotating turbines will then be converted into electrical energy and sent to the Dewa power grid.
To reuse the water, clean energy generated by the Mohammed bin Rashid Al Maktoum Solar Park will be used to pump it back through the tunnel and return it to the upper dam, making the project 100 per cent renewable.
The power plant's response time to heightened demand for energy is expected to be fewer than 90 seconds.

Andhra Pradesh Chief Minister YS Jagan Mohan Reddy conducted an aerial and physical survey of the Polavaram project construction site and took stock of the work in progress besides holding a review meeting on construction and rehabilitation works.
The Chief Minister walked on the spillway gallery and examined the ongoing works of the spillway. After the Irrigation Department officials and representatives of project contractor explained the progress of the works, and a review meeting, the Chief Minister said water will be released from Polavaram for Kharif 2022.
He said, “there is no change in the height of the dam. The rehabilitation works will be taken up on priority basis. Initially, the rehabilitation works with an estimated cost of Rs 3,330 crore will be started in flood prone areas when water storage is at 41.5 metre. Later, the storage capacity will be increased in a phased manner to 45.72 metre.”
The officials said the rehabilitation works would be completed by February-March 2021 and the project works by December 2021. Any minor pending works will be completed in two or three months and water can be released for Kharif 2022.
He instructed the officials to complete the works of spillway and spill channel by May 2021 as Godavari will be flooded again from June.
“At the same time take steps to fill the gaps in the cofferdam so that the works of main dam will be done swiftly,” he said and added that the hydroelectric project works should also be continued simultaneously.


The Koldam Dam Hydropower Project of the NTPC Limited, commonly known as KolDam, is an under construction embankment dam on the Sutlej River near Barmana on the Chandigarh-Manali Highway ( NH-21 ) and the border of Bilaspur district and Mandi district, Himachal Pradesh, India. The main purpose of the dam is hydroelectric power generation and it will support an 800 MW power station. The foundation stone for the dam was laid on 5 June 2000 by Prime Minister Atal Bihari Vajpayee. On 14 January 2004, main construction on the dam began. Due to problems associated with habitat and forest loss, the project has been delayed. Attempts to impound the reservoir first failed in December 2013 due to problems with sealing the diversion tunnels. By 18 March 2014, a fourth attempt to seal the tunnels and fill the lake was underway. Repairs were made and impounding was mostly complete in April 2014. Generator commissioning was original scheduled for 2009 but has been rescheduled to later in 2014 and 2015.

Maximizing Transportation Capacity of an Aged Crude Oil Pipeline
Proceedings Publication Date
Since November 1984 The 406.4 mm x 166 km has run from Meleiha field at Egypt's Western Desert to El-Hamra terminal on the coast of the Mediterranean Sea (Figure 1). Its original capacity was 100,000 barrels oil per day (BOPD) using two pumping stations. Planned pumped flow rate increased to 177,000 BOPD when Maximum Allowable Working Pressure (MAWP) reduced from 1463 psi to 950 psi. This paper shows how to increase flow rates without reaching MAWP, two methods are recommended: 1) loop the existing pipeline using a 406.4 mm x 56 km pipe. 2) Use a drag reducing agent (DRA) to reduce hydraulic friction losses and total dynamic pressure (TDP) thereby pumping more with reduced initial pumping pressure at Meleiha. Mathematical models are designed to simulate pumping operation through the whole system, with TDP predicted for three pipeline cases: 1) Normal case without both looping and DRA. 2) Oil pumping without DRA and with looping. 3) Oil pumping with both looping and DRA.


Irish Water will be submitting a planning application to Donegal County Council in the coming weeks for upgrade works at Kilmacrenan Wastewater Treatment Plant.
If granted, the project will involve the construction of a new wastewater treatment plant which will allow the existing plant, which is operating above its capacity, to be decommissioned.
The new plant will double the current capacity and allow for sustainable economic and population development over the next 25 years.
The proposed works at Kilmacrenan will also involve the construction of a new outfall to the Lurgy River, a new boundary fence and upgrade works to the existing entrance road.
The project will also involve the raising the site to prevent flooding from the adjacent Lurgy River. During construction the old entrance to the Church of St Finian and St Mark car park will be re-opened on a temporary basis for site access.
Irish Water will submit a planning permission application to Donegal County Council in the coming weeks in order to deliver these necessary upgrade works.
If the application is approved the contract for the construction of the Kilmacrenan Wastewater Treatment Plant will go to tender in the third quarter of 2018.

The dream of traveling north of St. Anthony Falls on the Mississippi River was made possible when Congress approved the Upper Minneapolis Harbor Development Project in 1937. This project included the construction of the Upper St. Anthony Falls Lock and Dam that was completed in 1963.
With a lift of 49 feet, the lock at St. Anthony Falls accounts for more than 10% of the total height change of the Mississippi River between the Twin Cities and St. Louis, MO. The Army Corps of Engineers also operates an observatory on this site. This Lock and Dam along with the Lower St. Anthony Falls Lock and Dam allow navigation to the head of the Mississippi River's 9-foot channel and spans the remnants of the Mississippi River's only waterfall.
The Upper St. Anthony Falls Lock and Dam offers tours of the facilities to scheduled groups.

THE Lesotho Highlands Development Authority (LHDA) has awarded a M494 million contract for the construction of a 132kV power line to South African company Mkhulu Electro Distribution Projects (Pty) Ltd.
According to the LHDA, the 38-kilometre power line will connect the existing Lesotho Electricity Company (LEC) transmission network in Matsoku Valley to the Polihali dam construction site.
This is the second of the two bulk power components of the Lesotho Highlands Water Project (LHWP) Phase II advance infrastructure. The project commenced in September 2019 and is expected to be completed in 2021.
LHWP is a multi-phased, multi-billion maloti project between the governments of Lesotho and South Africa.
It comprises water transfer and hydropower generation components with associated ancillary developments. The water transfer component entails the construction of dams and tunnels in Lesotho, enhancing the use of water from the Senqu (Orange) River and its tributaries by storing, regulating, diverting and controlling the flow to effect the delivery of specified quantities of water to South Africa, and utilising the delivery system to generate hydro-electric power in Lesotho.
Phase I included the construction of the Katse Dam, the transfer and delivery tunnels, ‘Muela Hydropower Plant and the Mohale Dam. The Phase II water transfer component comprises a dam at Polihali and a gravity tunnel that will connect the reservoir at Polihali with the Katse reservoir.
Commenting on the contract, LHDA chief executive Tente Tente said the award would facilitate the implementation of Phase II.
“Investing in the extension and upgrading of the bulk power transmission network in Lesotho is not only to facilitate the implementation of Phase II alone,” Mr Tente said.
“It will also bring long term benefits to the country by increasing access to power for people and businesses in remote areas, as was the case in Phase I of the LHWP.”
LHDA said the works under this contract include construction of a new, a 38-kilometer long 132kV line between the existing LEC transmission network in the Matsoku Valley to the Polihali Dam construction site, and the upgrading of existing LEC lines from Ha-Lejone to Matsoku, and Maputsoe to Katse.
“The upgrade comprises the installation of insulation and shielding earth conductors. The works also include the installation of optical ground wire (fibre) communication line from Maputsoe to Katse and Polihali. This line is intended to enhance communication at the project area.”
LHDA said Mkhulu Electro Distribution Projects has extensive experience in overhead transmission line construction and civil engineering projects in southern Africa including in Namibia, South Africa, Botswana and Mozambique.
“In March 2019, the LHDA awarded the tender for the construction of a 33kV line and the diversion of an existing 33kV LEC distribution line to LSP Construction at a contract value of M41 million. The 33kV line, which is constructed from the existing Letšeng/Mokhotlong distribution network will supply power to the Polihali construction village site, temporarily.
“Sections of an existing LEC 33kV distribution network between Letšeng and Mokhotlong, will be submerged in five different positions by the new Polihali Dam at full supply level necessitating the diversion of the existing line,” the LHDA said in a statement.

- Mission Springs Water District Vista Reservoir No. 2 Project
- Mission Springs Water District (MSWD or District) is proposing to develop a second reservoir at the exiting Vista Reservoir site. The existing Vista Reservoir site is approximately 1.23 acres and is surrounded by mountain terrain consisting of mild to steep slopes and an earthen driveway up to the existing 300,000-gallon reservoir pad at 1,609 feet in elevation. The existing reservoir is connected to two different pressure zones via a 10-inch waterline and a hydropneumatic station with a 4-inch waterline. The proposed Vista Reservoir No. 2 Project includes a new 300,000-gallon reservoir approximately 30 feet northwest of the existing reservoir. Ultimately the installation of the new 300,000-gallon reservoir at the Vista Reservoir site will require installation of the following: retaining walls and hillside slope stabilization, stormwater management BMPs, installation of a new access road, relocation of the existing hydropneumatic station and the electrical cabinet, grading, wrought iron and chain link fence, and a new 300,000-gallon welded steel water storage reservoir and related piping. Design and construction of the Project is anticipated to be completed in approximately 6 months. Construction is anticipated to start in the third quarter of 2021.

A coupled stream flow and depth-integrated subsurface flow model for catchment hydrology

- Journal of hydrology 2015 v.530 pp. 66-78
- aquifers, equations, gravity, hydrodynamics, hydrologic models, runoff, stream flow, streams, subsurface flow, vadose zone, watershed hydrology, watersheds
- Few hydrological models that couple stream flow and subsurface flow in shallow aquifers are based on a compromise between simple and complex depiction of the system, although this compromise could result in tractable tools for various applications. We present a depth-integrated approach in which flows in the vadose and saturated zones are assumed to be parallel to the bottom of the aquifer and thus are integrated in the direction normal to the bottom of the aquifer. The hydrodynamic parameters are also integrated in this direction, and gravity effects are preserved. Stream flow is handled by a diffusive-wave equation that is calculated over a network of one-dimensional bonds. The first-order coupling between the stream and subsurface flows exchanges water fluxes between the stream network and the subsurface compartment according to the hydraulic head differences between the systems. Three synthetic test cases, one including a comparison with a three-dimensional code, are used to evaluate the general behavior of the coupled model. It is shown that the approach reproduces the main hydrological features at the catchment scale, including the generation of runoff, infiltration–exfiltration into (from) the vadose zone, and smooth transient head variations in the aquifer.

All Valve Industries offers a new line of pressure reducing valves designed for use in commercial and industrial environments.
The Caleffi 536 series pressure reducing valves are pressure control valves that protect sensitive equipment downstream of the valve from high pressure and fluctuations in pressure.
The 536 series pressure reducing valve features a high maximum inlet pressure up to 2,500kPa, and is able to reduce the pressure to as low as 50kPa and up to 600kPa using a standard allen key.
These pressure reducing valves are also rated up to a higher temperature of 80ºC compared to other pressure reducing valves available from Caleffi.
Designed to obtain optimum fluid dynamic characteristics, the internal layout has made it possible to achieve a noise level of less than 20 dB.
This attribute has helped Caleffi reducing valves receive approval for inclusion in the I acoustic group in compliance with the EN 1567 European standard.
Additionally, the internal shape of the reducing valve enables it to attain low pressure losses even when a large number of draw-off points are open.
Components that are likely to undergo wear due to the friction of moving parts are all PTFE coated, substantially increasing the life of the pressure reduction devices. The stainless steel seat also contributes to the long-lasting operation of the valve.
- High maximum inlet pressure up to 2,500kPa, reduced to as low as 50kPa
- Rated up to a higher temperature of 80ºC
- Unique internal layout helps achieve noise level of less than 20 dB
- PTFE coated components


The Bailey Dam Local Protection Project is located on the Winooski River in Montpelier. The project reduces ice jams and resultant flooding on the Winooski River. Data on damages prevented are not available. Bailey Dam, originally called the Montpelier Dam, was completed in October 1934 as part of the Winooski River Local Protection Project. The work described below was completed between August-November 1975 as a small project under Section 208 of the Continuing Authorities Program. Construction was overseen by the Corps’ New York District. The project cost $250,000 and is operated and maintained by Montpelier. The project included the removal of the dam’s tainter gates and supporting piers, a concrete walkway, and a portion of the spillway; and the construction of an approximately three-foot-high concrete cap on top of the existing sill and a six-foot-high cap on the spillway.

|Publication Year :||2021|
|Abstract:||近年來流域內的河川水位因暴漲而溢堤，導致堤內地區的嚴重淹水災害增加。若能有快速且精度良好的流域淹水模式，將可提升流域尺度的災害應變能力。現有的NTU-CAFIM模式(National Taiwan University Cellular Automata Flood Inundation Model)經過發展，已可提供快速且精度良好的都會區地表淹水模擬，如能將其與一維河川變量流模式進行耦合，便可提供即時的流域淹水模擬，對於防災應變有所助益。|
In recent years, serious flooding in areas near the river due to river embankment overflowing is increasing. To promote disaster prevention and protection for the whole river basin, a fast and accurate inundation simulation model is required. The existed National Taiwan University cellular automata flood inundation model (NTU-CAFIM model) can fastly and accurately provide a prediction of flooding in urban areas, thus it is appropriate to be coupled with the 1D unsteady river flow model to provide real-time forecasting of flooding in the river basin.
In this study, the 1D unsteady river flow model (RFM) is coupled with the NTU-CAFIM model (OFM), so that water can be dynamically exchanged through embankments of each river reach. Rules to describe exchanged water are developed for coupling the RFM and OFM, including the correspondence of different spatial resolutions between riverbank cells in the OFM and river reaches in the RFM, and the calculation of exchanged volume between riverbank cells in the OFM and river reaches in the RFM. In particular, the exchanged volume between the RFM and OFM through embankments along each river is calculated by either free or submerged weir flow formulas.
To verify the water exchanging rules in this study, two case studies are selected, and the coupled model is compared with the HEC-RAS model by indicators such as Nash-Sutcliffe efficiency (NSE), accuracy (ACC), and sensitivity (TPR). Based on the simulation results of a small-scale ideal case and the case of the Severn River Basin in the United Kingdom with an area of 24km2 and actual complex terrains. The simulation results of the coupled model in the hydrographs of water level in river sections, the hydrographs of flow rate in river sections, the hydrographs of water levels in two-dimensional overland flow, the hydrographs of water overflowing, and the maximum flooding area are very similar with the HEC-RAS model. Furthermore, in the ideal case and the real case of the Severn River Basin, the coupled model is 47% and 41% faster than the HEC-RAS model. The above results indicate that the coupled model is as accurate as the HEC-RAS model with a significant reduction in its computational time. Hence, it is concluded that the coupled model has considerable potential to be applied to real-time simulation of flooding in the river basin.

From 1936-1939, Bartlett Dam was constructed by Reclamation on the Verde River, 48 miles northeast of Phoenix. This multiple-arch dam is 287 feet high, contains 182,000 cubic yards of concrete, and creates a 178,490 acre-foot capacity reservoir.
Bartlett Dam was modified by Reclamation between 1994 and 1996 to address safety concerns. The modification included construction of a new, unlined auxiliary spillway about 1,500 feet south of the dam's left abutment, along with a concrete control structure and three-segment fuseplug embankment along with training dikes. In addition, the dam was raised 21.5 feet to prevent overtopping, and the walls and bridge of the existing service spillway structure were modified. Modifications were begun in March 1994 and completed in December 1996.


The assessment of the seismic safety of gravity dams is a topic of great importance in civil engineering. In this paper, fluid structure interaction modeling of gravity dams during earthquakes is investigated. In particular, this work aims to provide physical significance of a plan numerical model simulating the dam and the infinite length reservoir when a horizontal ground motion acts at the dam foundation. After a preliminary calibration of the model with analytical solutions, the dynamic properties of the numerical model are investigated via modal and frequency response analyses. The fully coupled mechanical-acoustic model is also compared to the widespread “added mass” model  adopted in most national codes.

In this study, the sedimentation status of Qazvin irrigation network was investigated before and after the construction of the reservoir reservoir of Taleghan. Sediment field studies show that the main source of network sediments before the construction of reservoir dam was sediment produced in the catchment area of the Taleghan river basin. After the construction of the dam, most of these sediments deposited in the lake of the reservoir, and now clear water flows through the tunnel to the Zayaran River. With the construction of a reservoir dam, it was expected that the problem of deposition in the network would be resolved, but there is already a precipitate in the network due to various factors. For example, despite the removal of the major part of sediments in Taleghan Dam reservoir, due to the existence of intermediate watersheds, some of the sediments are entering the Qazvin Irrigation Network between the tunnel output and the dam site. Other factors include the inadequate route of the main canal service and second grade canals and the entry of soil from the service roads into the canal. The debris of the rubble, especially in the intervals of the canal, passing through the residential areas, the entry of municipal waste and sewage into the canals, the car wash in the canal service road, the entry of surface water from the rain into the canals, and, finally, the heavy traffic of heavy machinery On the road, canals can be considered as one of the other important factors in the formation of sediment in the network. Another important factor in the formation of sediment in the grid is the manipulation of the hydraulic performance of the amyl valves (by inserting sand traps on the valves) by farmers, which reduces the flow velocity at the upstream of the valve and the accumulation of fine grained sediments in the upstream valley The coarse-grained amylate and torn bags also introduce coarse deposition into the canal right after the amyl valve. Meanwhile, since the sediments of the Taleghan River (before the construction of the reservoir dam) still exist within the canals, it is therefore necessary to dredge the entire network in order to remove the precipitates.

Experimental hydrology data from the Mizunami Underground Research Laboratory in Central Japan have been used to develop a site-scale fracture model and a flow model for the study area. The discrete fracture network model was upscaled to a continuum model to be used in flow simulations. A flow model was developed centered on the research tunnel, and using a highly refined regular mesh. In this study development and utilization of the model is presented. The modeling analysis used permeability and porosity fields from the discrete fracture network model as well as a homogenous model using fixed values of permeability and porosity. The simulations were designed to reproduce hydrology of the modeling area and to predict inflow of water into the research tunnel during excavation. Modeling results were compared with the project hydrology data. Successful matching of the experimental data was obtained for simulations based on the discrete fracture network model.

(ECNS) -- As a project of the Yalong wind and solar power base, the world's highest-altitude pumped--storage power station on Yalong River, started construction in Daofu County, Tibetan Autonomous Prefecture of Garze, Sichuan Province, the Science and Technology Daily has reported.
Located at an altitude of 4,300 meters, the power station has a total designed installed capacity of 2.1 million kilowatts, with an annual generation of over 2.994 billion kilowatt-hours of electricity.
As the largest pumped storage power station in Sichuan, it is equipped with six reversible units, each with a capacity of 350,000 kilowatts. The station consists of an upper reservoir, lower reservoir, water conveyance system, underground powerhouse system, and surface switchyard.
Pumped-storage power stations use off-peak electricity to pump water to higher locations, where it is stored and then released to generate electricity when the power supply is strained. They can complement wind and solar power generation, which brings bigger fluctuations to the grid, said Zhang Peng, deputy general manager of the Yalong River Hydropower Development Company.
The station is expected to store 12.6 million kilowatt-hours of electricity daily, which can meet daily power consumption of 2 million households in Sichuan.
The Yalong wind and solar power base, a large-scale clean energy demonstration base in China, has put into operation nearly 21 million kilowatts of hydropower and new energy so far and completed construction of 78 million kilowatts of installed capacity for 2035, making it the world's largest base of green and renewable energy.

From The Pueblo Chieftain (Chris Woodka):
A hydropower project at Pueblo Dam has been given a green light by the Bureau of Reclamation and is in line for a $17.4 million state loan.
A finding of no significant impact was issued last week for the project being spearheaded by the Southeastern Colorado Water Conservancy District. Other partners in the project are Pueblo Water and Colorado Springs Utilities.
The Southeastern district will seek a $17.4 million loan for the project from the Colorado Water Conservation Board today. The loan would be for 30 years at 2 percent interest.
A 7 megawatt hydropower facility is anticipated at the north outlet works, which was constructed by Utilities as part of the Southern Delivery System.
“A hydropower plant and associated facilities will be constructed at the base of Pueblo Dam, utilize the dam’s north outlet works and immediately return flows to the Arkansas River downstream of the dam,” said Signe Snortland, area manager of Reclamation’s Eastern Colorado Area Office.
The next step will be negotiation of a lease of power privilege contract.
About 1.4 miles of new power and fiber optic lines also will be constructed to connect the hydropower plant to Black Hills Energy’s substation at Lake Pueblo.
Construction is expected to begin later this year, with the first power generation to begin in 2018.

Francis Turbine Trainer HM 430C
Francis Turbine Trainer
|Name:||Francis Turbine Trainer|
The Basis for Grid Connection
Francis turbines are used with medium drop heights and medium flow rates. The areas where Francis turbines are employed are therefore extremely diverse:Run-of-the-river power stations Storage power stations Pumped storage power stations
The Francis turbine's adjustable guide blades allow constant speeds to be maintained under different conditions. Maintaining constant speeds is necessary in order to be able to feed the electricity that is generated into the grid. The different conditions include different drop heights, for example.
HM 430C has a special brake unit which makes constant speeds possible. As such, the typical characteristics of the Francis turbine can easily be represented using the dependences of the following variables:
User-friendly software allows the process to be easily controlled and the relevant parameters to be monitored.

Plan to replace Kates Street culverts
Toowoomba Regional Council is in the early stages of design for a project to replace the culverts on Kates Street in Clifton.
The culverts lie within a drainage channel that captures water run-off from the upstream catchment to divert flows away from the populated areas to the west of the channel.
The project is being undertaken to improve drainage.
It will include removing the existing six-cell concrete box culverts and replacing them with larger reinforced concrete box culverts with associated culvert inlet and outlet drainage work.
A new concrete pathway will be constructed over the new culverts on the southern side of Kates Street with new road pavement and kerbing across the culverts.
The existing timber bridge and concrete pathway will be demolished.
Consideration is being given to constructing a new concrete pathway on the northern side of Kates Street.
Council says the construction project will be subject to funding being available.
A time frame has yet to be determined.
