The South-East Queensland Regional Water Supply Strategy is securing future water supplies, which includes a regional water grid and new water storages. The Queensland Government’s contribution to future water supplies includes Traveston Crossing Dam on the Mary River, Wyaralong Dam on the Teviot Brook, and Bromelton Offstream Storage and Cedar Grove Weir on the Logan River.
Queensland Water Infrastructure (QWI) was established by the Queensland Government in June 2006 to progress feasibility studies, design and construction of this new water infrastructure. QWI commissioned SunWater to investigate much of this infrastructure to preliminary design level for the impact assessment process and as supporting information for potential alliance partners for the delivery of the projects. The work undertaken included extensive geotechnical investigations, hydraulic modelling, hydrologic modelling and design activities. This paper outlines the investigations associated with the preliminary design of this infrastructure and process of risk and opportunity identification to establish the program and budgets for these projects.
Stage 1 of Traveston Crossing Dam is to be constructed by the end of 2011, with a storage capacity of 153,000 ML providing a yield of 70,000 ML each year. The design adopted for the dam consists of a roller compacted concrete structure across the valley floor with an earth embankment section on the left abutment. In order to limit inundation upstream and mitigate flooding in Gympie, a gated spillway on the right abutment has been adopted. The Traveston Crossing Dam has an estimated project cost of $1,700 million.
The design developed for the Wyaralong damsite provides a reservoir with storage capacity of 103,000 ML and a yield of 21,000 ML each year when operated in conjunction with Cedar Grove Weir. Preliminary designs have been prepared for three types of dam, which are all considered technically feasible for the site. They are a roller compacted concrete dam, an earth and rockfill dam and a concrete faced rockfill dam. The Wyaralong Dam has an estimated project cost of $500 million.
The Bromelton Offstream Storage, of earthfill construction, provides a storage capacity of 8,000 ML and Cedar Grove Weir, a sheet pile structure, provides a storage capacity of 1,000 ML and both are to be constructed by the end of 2007.

An important aspect of improving the safety of dams is selecting designs that are both hydraulically efficient and cost-effective. A powerful tool that can be used as part of the hydraulic structure design process is a physical model study. To obtain maximum benefit from the model, it should be implemented as a part of the design process rather than as a post-design verification phase. A model study included early in the conceptual design phase can also provide increased flexibility to the designers.
Hydraulic model studies can often provide cost-effective answers to difficult problems. Some of the issues that can be efficiently resolved using model studies include optimizing spillway head-discharge relationships to increase reservoir storage while minimizing upstream flooding potential, controlling downstream scour, quantifying hydraulic uplift forces and/or overturning moments of dam structures, evaluating alternatives for structure retrofit or repair, and optimizing control gate sequencing during floods. Model studies also allow the engineer to simulate prototype performance (e.g., three-dimensional flow patterns, velocities, pressures, scour potential) over the full range of expected discharges. Quick and easy changes to the model can be made at minimal cost when evaluating the performance, safety and economic impact of various design alternatives.This hands-on model study approach to dam safety represents a tool that in some cases is underutilized.
Brief discussions of several physical model studies conducted at the Utah Water Research Laboratory, Utah State University in Logan, Utah, USA, are presented to illustrate key points of the paper. The primary objective of each of these model studies was to provide and/or improve the safety of the dam and the spillway while minimizing construction costs. This paper discusses the cost-effectiveness and hydraulic improvements that can be achieved through physical model studies.

For an ogee-shaped spillway crest, it is well recognised that sub-atmospheric pressures will develop on the lower-nappe profile for operating heads greater than design head. This effect is useful in providing an increase in efficiency of the spillway discharge for small increases in operating head. However, there is limited data on the formation of sub-atmospheric crest pressures for high-head operation above 1.3 times greater than the design head
This paper reports on modelling work done by GHD and the Water Corporation for the Wellington Dam Remedial Works Project in Western Australia where the current design flood has increased to more than twice the original design head. Two-dimensional physical scale modelling and 3-D Computational Fluid Dynamics (CFD) modelling of the existing Wellington Dam spillway profile was carried out to determine the discharge coefficient and uplift force generated by the formation of sub-atmospheric crest pressures under high-head operation.
The paper compares the results of the physical scale model and the CFD model and earlier published data by Cassidy (1970) and concludes that there exists a good correlation between the three data sets.

The Aviemore Dam appurtenant structures were upgraded for seismic performance in 2006. A comprehensive dam safety review programme conducted by Meridian Energy evaluated the performance of the dam and appurtenant works under extreme ground movements and rupture displacements of the Waitangi Fault, which passes through the embankment dam foundation. The spillway and sluice gates are key elements of the dam safety critical plant for the passage of floods to prevent overtopping or emergency dewatering of the reservoir after a major seismic event if there are concerns about damage to the dam. This paper outlines the assessment undertaken for the spillway and sluice gates for seismic performance and the upgrade necessary to safeguard their integrity for operation after the event.
The spillway and sluice gates are large steel radial gates operated by electrically powered wire rope winches and hydraulic actuation, respectively. Combined hydrostatic and the Safety Evaluation Earthquake (SEE) induced hydrodynamic loads would be expected to stress the gate structures beyond their yield capacity. The yield would be downstream only due to the influence of the hydrostatic load under the earthquake response cycle. The resulting deformations were predicted to fracture connecting bolts in the spillway gate arms and cause severe leakages past the top leaf of the sluice gates. The solutions developed for the spillway gates to reduce connection bolt damage and the strengthening of the sluice gates will ensure their post-earthquake operation.
Keywords: Aviemore Dam, spillway, sluice, radial gate, seismic performance, post-earthquake operation.

The use of Computational Fluid Dynamics (CFD) models in the dams industry has increased significantly in recent years and conversely the use of physical hydraulic models has decreased. Typical design approaches for an upgrade of similar magnitude to the Hinze Dam Stage 3 project would have allowed for considerable time to develop a preliminary spillway design before hydraulic modelling was introduced, potentially requiring only one type of model. So is there a need for both types of models?
Because of the complex hydraulics associated with the spillway required for the Hinze Dam Stage 3 raise and accelerated schedule, the utilisation of CFD and 1:50 Froude Scale physical hydraulic models was necessary. Both models were constructed independent of each other. Both models complemented each others strengths and weaknesses, and each provided critical information at the following different stages of design:
• Spillway selection and conceptual design stage – the CFD model results were highly valuable in steering the selection of spillway type and configuration, particularly with visual representations of the ranges of flow for each spillway option.
• Preliminary design – in a one week period, 90 to 95% of the final spillway layout was resolved with interactive modifications of the physical hydraulic model.
• Detailed design – both the physical hydraulic model and the CFD model were utilised to determine water pressures, velocities and water surfaces and evaluate cavitation potential as input to detailed design.
In the case of the Hinze Dam Stage 3 project, it was highly advantageous to utilise a CFD and physical hydraulic model to achieve the design outcomes at each phase of the design. The dual-model study approach also provided advantages for project management of the design and stakeholder involvements.

Hydropower projects considered in Uzbekistan
On November 30, President of the Republic of Uzbekistan Shavkat Mirziyoyev got acquainted with the presentation of projects in the hydropower sector.
The energy industry is actively developing in Uzbekistan. In addition to power plants based on traditional fuels such as oil and gas, facilities are also being built that generate electricity from renewable sources - sun, wind and water.
In particular, in 2017, by the decree of the President, the joint-stock company Uzbekgidroenergo was established. Over the past period, 11 new hydroelectric power plants have been built and 8 modernized. As a result, additional power generating capacities of 244 MW have been created.
However, the country's hydropower potential is only half used. In this regard, 21 major projects for the construction of power plants with a total capacity of 740 MW have been developed. In particular, next year it is planned to implement 7 projects with a total capacity of 170 MW, in 2023-2024 - 12 projects with a capacity of 150 MW, in 2025-2026 - 2 projects with a capacity of 420 MW.
During the presentation, instructions were given on high-quality construction and ensuring the sustainable operation of these structures.
The head of state paid special attention to the construction of small hydroelectric power plants that do not require the construction of dams, stressing the need to involve the private sector in this area.
To date, a list of 22 promising sites has been formed, on which, on the basis of a tender, it is planned to build a mini-hydroelectric power plants with a capacity of up to 5 MW.
It is also indicated that it is possible to install compact hydropower plants with a capacity of up to 500kW to supply power to villages located along rivers and canals, such as Naryn, Sokh, Tankhoz, Akbulak, Ugam. The list of such sites will be announced to the population and entrepreneurs. It has been determined that the benefits and subsidies given to individuals and entrepreneurs for the installation of wind power plants will also apply to small hydropower plants.
They the issue of training qualified specialists for the operation of hydraulic structures was also touched. It was noted that higher educational institutions in the field of technology, irrigation and architecture need to strengthen work in this direction, create educational laboratories for construction and hydraulics.

How the StreamClean GPT Works
The StreamClean GPT consists of a circular chamber (plus risers if required) with a diversion channel:
A diversion channel is designed to divert stormwater from the main stormwater drainage system into the storage chamber.
A storage chamber which allows for the removal of gross pollutants, sediment, light litter, oil & grease prior to returning the stormwater to the main drainage system.
A screen is provided to prevent particles of 3mm diameter (and larger) from passing through the arrestor.
The main factors which allow for sediment removal are:-
Water velocity reduction via a vortex action
Water velocity reduction via detention
Stormwater from the main stormwater drainage system enters the diversion channel wherein a baffle diverts the stormwater to the storage chamber.
In the storage chamber the stormwater is forced into a vortex action and travels around the storage chamber. Oil & grease will rise to the surface where it is retained.
Pollutants and sediment within the stormwater are forced to the inside of the storage chamber. Sediment falls to the base of the GPT where it is retained. The cleansed stormwater leaves the storage chamber via the screen and outlet spigot, through the diversion channel and rejoins the main stormwater drainage system.
The StreamClean GPT unit is designed for use in non-pressure stormwater systems.

The British company Gilkes has recently completed the Ruo-Ndiza hydroelectric project. The project carried by Mulanje Renewable Energy injects 8.2 MW into the national grid.
The Ruo-Ndiza hydroelectric project is definitively completed. Its second phase was recently commissioned by Gilkes. The company, based in Kendal, UK, implemented the project on behalf of Mulanje Renewable Energy. The second phase of the project allowed for the construction of a run-of-river power plant, i.e. a facility that does not depend on a water reservoir for its operation.
The plant was built on the Ruo River at the foot of Mount Mulanje near the town of Blantyre in southern Malawi. The facility is equipped with two 3.3 MW Pelton turbines. The first phase of the project was already a run-of-river power plant built on the Ndiza River. Gilkes commissioned this facility in 2019.
The 8.2 MW of power generated by this facility is sold to the state-owned Electricity Supply Corporation of Malawi (Escom) under a Power Purchase Agreement (PPA) signed in September 2018. “After seeing the shortfall in the country’s power generation, we proposed to bring in power from the Ruo and Ndidza Rivers, which would mitigate outages on the national grid,” said Ian MacKersie, Managing Director of Mulanje Renewable Energy in 2019.
Ruo-Ndiza is one of several renewable energy projects completed or under development to increase the East African country’s installed capacity to 363 MW in 2018. Among the major initiatives in Malawi’s energy sector is the Mpatamanga hydroelectric dam under development in the south of the country.
The reservoir will be installed on the Shire River in the Blantyre district, downstream of the Nkhula A HPP & Nkhula B hydroelectric dam, the Tedzani hydroelectric dam and upstream of the Kapichira hydroelectric dam. The Mpatamanga Dam will operate with a hydropower plant that will produce 258 MW.

REPAIRS TO THE El DORADO Irrigation District’s (EID) diversion dam, located in Kyburz, California, US, have been completed. The rehabilitation included a new concrete dam, gates and and software to automatically operate the by- pass gates.
The diversion dam, along with the power house, canal and other EID infrastructure was severely damaged by a flood in 1997. Pacific Gas and Electric owned the project at the time but sold it to EID after the flood. The diversion dam is part of Project 184, the federally licensed hydroelectric system made up of four manmade lakes, 36.2km of canal and the El Dorado power house.
The system provides one-third, (18.6Mm3) of EID’s water supply. The Kyburz diversion dam redirects the water from the South Fork of the American river into the El Dorado Canal, which carries the water to Forebay Reservoir in Pollock Pines. The water is then used by area communities, such as Camino and Pollock Pines. In 2002, the water will also be used to power the El Dorado Powerhouse, as it did prior to the 1997 flood. The powerhouse is located at river level, north of Pollock Pines, 580m below the reservoir.
Ford Construction, the general contractor that built the new dam, began work in November 2000.
The new concrete dam cost US$370,000 for construction management and design engineering and a futher US$3.6M for the construction itself.


Ground breaking is finally set for the construction of the P75 million Bitan-ag Bridge and Approaches.
The project also includes drainage improvement in the area as shown in the tarp below.
Hopefully, the project will solve the perennial flooding in the area. By the way, heavy traffic is expected onsite as construction work begins on the bridge.

Building dikes is another way to control the river and improve navigation. The dikes are usually built near river crossings to direct the flow as it crosses from one bend to another. Also, the dikes are used to prevent a secondary channel from capturing a larger part of the river's flow, which would make the main channel inadequate for flood control and navigation. Without dikes these areas have to be dredged more often to maintain the required channel depth.
Although the dikes at Hogpoint appear to be above the river surface in this picture, they are actually below the surface.

Dredging is necessary to maintain the channel depth and width for navigation. Different types of dredges (cutterhead, dustpan, hopper) are used depending upon the area.

An On-line Automatic Flow Measurement Method for an Open Channel under Complex Flow Conditions
International Journal of Control and Automation
Buildings flow measurement method using the pre-established upstream and downstream water levels and flow to estimate the flow is the common method for open channel flow measurement. However, due to the changes of import and export, flow pattern, and hydraulic boundary conditions, traditional mechanism modeling-based flow measurement methods which establish the relation between the upstream-downstream water levels and flow by historical records and empirical equation models are usually not able
... re usually not able to meet the demands of precision and adaptability. The improvement is based no the neural network (data-driving). However, the neural network based method is commonly offline and the model parameters are constant in the application.If the degree of opening of the weir sluice gate changes frequently, it is hard to construct a neural network model of high precision for on-line and real-time measurement. This research designs a real-time on-line automatic measurement system, for the Pi River canal weir gate, that collects upstream and downstream water levels and the degree of opening of the gate. Moreover, it establishes a three layer BP neural network model based on on-line real-time data correction. This model comprised of a Kalman filter with forgetting factor and a three layer BP neural network data fusion center. In contrast to the standard hydrometric propeller based method, the average relative error is lower than 5%, meeting the "River Discharge Measurement Criterion" proposed by Ministry of Water Resources of the People's Republic of China. Both the precision and the repeatability can cater for the engineering applications.

MASERU — Chinese construction company, Sinohydro Corporation Limited says it expects to employ at least 400 locals during the construction of Metolong Dam.
The company revealed this on Monday during the signing of a contract with the Metolong Authority for the construction of the Metolong Dam and Raw Water Pump station.
Sinohydro Corporation’s Cao Yuesheng said another 100 Chinese would be engaged in managerial positions to oversee the project.
“The locals who would be engaged will be given training,” he said.
He added that local contractors would be given sub-contract jobs depending on their areas of specialisation and capabilities.
Sinohydro Corporation Limited said the M540 million project represents a major milestone in the realisation of the Metolong Dam and Water supply project.
The Metolong project which is expected to be completed by 2013 is being funded by the government of Lesotho, South Africa, the World Bank, the Millennium Challenge Corporation and the European Investment Bank.
The project is divided into five components including: advance infrastructure planning, the construction of the Metolong dam and raw water pumping station, water treatment works, the construction of a downstream conveyance system, and environmental and social management.
The dam will provide 75 000 cubic metres of water per day to Maseru and the surrounding towns of Roma, Mazenod, Morija and Teyateyaneng.
The dam wall to be built on the Phuthiatsana River in the Thaba-Bosiu area will be 73 metres high.
It will have the capacity to hold 53 million cubic metres of water.
Metolong Authority’s chief executive Adris Mahmoud said the construction of the dam is part of Lesotho government’s commitment to improve access to clean water for Basotho.
He said apart from improving water supply for domestic use to Maseru and the surrounding towns the Metolong project will also stimulate the country’s economy.
“A reliable water supply will lead to continued development of manufacturing and textile industries. This will in turn result in job creation, food production and poverty alleviation,” he added.


The Boguchanskaya GES is a hydropower plant under construction on the Angara River in the Krasnoyarsk district Territory. It is included in the Angara cascade of hydropower plants. Its location is the town of Kodinsk, Kezhemskiy district of the Krasnoyarsk Krai. The construction of HPP began in 1980, preparatory works began in 1974. According to the approved project the plant must have the hydroelectric capacity of 3,000 MW. The building of HPP should include 9 radial-axial generating units with the capacity of 333 MW.


A three-dimensional transient numerical simulation was conducted to study the pressure fluctuations in low-specific-speed centrifugal pumps. The characteristics of the inner flow were investigated using the SST k-ω turbulence model. The distributions of pressure fluctuations in the impeller and the volute were recorded, and the pressure fluctuation intensity was analyzed comprehensively, at the design condition, using statistical methods. The results show that the pressure fluctuation intensity increases along the impeller streamline from the leading edge to the trailing edge. In the impeller passage, the intensity near the shroud is much higher than that near the hub at the inlet. However, the intensity at the middle passage is almost equal to the intensity at the outlet. The pressure fluctuation intensity is the highest at the trailing edge on the pressure side and near the tongue because of the rotor-stator interaction. The distribution of pressure fluctuation intensity is symmetrical in the axial cross sections of the volute channel. However, this intensity decreases with increasing radial distance. Hence, the pressure fluctuation intensity can be reduced by modifying the geometry of the leading edge in the impeller and the tongue in the volute.

KPH Construction is taking its services across state borders. Work is already underway at the United States Army Corps of Engineers Argentine Unit pump station in Kansas City, Kansas. This project calls for the upgrades and building of pump stations for a critical piece of the levee unit protection system in Kansas City.
The project has kicked off with the Turner Avenue pump station, which requires the least amount of work to be done. However, it is receiving one of the heaviest single pieces of structure on the entire project. KPH Construction is installing a 60,000-pound monolithic precast concrete extension to raise the height of the existing pump station.
This extension is to increase the capacity and head pressure of the pump station, which will accommodate a future levee upgrade the U.S. Army Corps is currently planning. As part of this scope, KPH Construction is installing new galvanized railings, platforms, gratings and ladders for safe access and maintenance of the pump station’s gate valve system.
By quickly knocking out the work to be done at the Turner Avenue pump station, KPH Construction can turn its full attention to the two new pump stations set to be constructed. Sheet piling and deep foundation excavation is slated to begin in a few short weeks. Talk about getting the heavy lifting out of the way first.

Imaichi Pumped Storage Power Station
The Imaichi dam serves as the lower reservoir for the 1,050 MW Imaichi Pumped Storage Power Station, while the Kuriyama Dam forms the upper. Its reservoir can store 9,100,000 m3 (7,377 acre·ft) of water. Of that storage volume, 6,200,000 m3 (5,026 acre·ft) can be used for power generation. The power plant operates using the pump-storage hydroelectric method. During periods of high electricity demand, water is sent from the upper Kuriyama Reservoir to the power plant which contains 3 x 350 MW Francis pump turbines. Water discharged from the power plant then enters the Imaichi Reservoir. When demand is low, the pump-generators reverse mode and pump water from the lower reservoir back up to the upper.

Reno Mattresses for Hydraulic engineering work
In 2013, a significant flood occurred in the Heilongjiang Province of China. Many provincial hydraulic engineering works were seriously damaged. The system management and flood prevention measures on major rivers was reviewed and an emergency water damage repair project was launched with 380 million RMB of state funds.
In July 2014, the river training works on the main stream of 3 rivers (Amur River, Songhua River and Nen River) in Heilongjiang Province were commenced, with a total length of 2,955 km of embankments and 24 billion RMB of total investment. In order to provide suitable scour protection to the channels and flood protection measures, 0.23m and 0.3m thick Reno Mattresses were specified.
Reno Mattresses are large flat double twist wire mesh units that are filled with hard, durable rock to form revetments within river and hydraulic control works. They provide high performance scour protection, protecting the river banks from erosion. Since the start of the project, Maccaferri supplied nearly 20 million m2 of Reno Mattresses in this project. Due to the presence of ice loads during winter and spring, the mattresses were specified with increased strength wire mesh for the mattress lids.
From 2nd half of 2014 to the end of June in 2016, the contract amount for Maccaferri China for this project has been approximately 100 million yuan (€13.4 million) of which 90 million yuan (€12 million) was Reno Mattresses.

A flood warning continues until Sunday morning for parts of the Illinois River affecting Adair, Cherokee and Delaware Counties, according to the National Weather Service.
The runoff from Thursday evening’s rainfall will push water levels to minor flood stage at Watts, Chewey and Tahlequah gages.
The Grand River Dam Authority submitted updated river levels Friday afternoon.
Under these conditions, the extreme turbulence makes the Illinois River too hazardous for floating.
The Illinois River near Watts at the US-59 Bridge in Adair County was at 16.51 feet at 1:30 p.m. Friday. The flood stage is 13.0 feet. It may crest at 17.6 feet Friday evening. That is 3 feet more than forecasted Friday morning. At 17.0 feet, moderate flooding occurs from the Arkansas border to Fidler`s Bend. Farmlands and permanent campgrounds are affected. A few cabins in the Fidler`s Bend area may have minor
Flooding. The river will fall below flood stage Saturday before dawn.
At 1:15 p.m. Friday, the stage near Chewey at the Hampton Bridge in Adair County was 9.69 feet. The flood stage there is 12.0 feet. It is forecasted that the Illinois River at Chewey is expected to rise above flood stage Friday evening and crest at 13.6 feet by late Friday night.
At 13.0 feet, minor flooding occurs from near Fidler`s Bend to near Hanging Rock. Water begins to affect access to Winset Hollow. Road access near the river to residential homes southeast of Chewey Bridge may be compromised. Water impacts 630 Road east of the Cherokee/Adair County line. The river at Chewey is expected to fall below flood stage late Saturday morning.
At 1:30 p.m. Friday, the Illinois River near Tahlequah at the US-62 Bridge in Cherokee County was at 8.76 feet. The flood stage is 11.0 feet, and moderate flooding is forecasted.
It is expected to rise above flood stage Friday night and continue to crest near 14.3 feet by early Saturday afternoon. At 14.0 feet, moderate flooding occurs from Hanging Rock downstream towards Tahlequah. Access roads east of the Combs Bridge near Eagles Bluff will be impassable. The river is expected to fall below flood stage Sunday morning.

Tajikistan launches first part of conveyor at Rogun dam construction site
AKIPRESS.COM - President of Tajikistan visited the construction site of the Rogun dam on July 25. The President was accompanied by Prime Minister Kohir Rasulzoda to see the progress of construction carried out around the clock at 78 blocs.
The first stop was made at the construction site of the first unit of the dam. 48 equipment items were installed there so far.
The President partook in the ceremony of inauguration of the first conveyor, which stretches for 4,200 m. It was built by Salini Impregilo for delivery of sand and stones for construction of the dam.
Over 50 million cbm of sand, stones and other construction materials were stored for construction of the dam. After construction of the second part of the dam, the conveyor will make 9 km until the top of the dam.
Rogun hydropower plant is the 9th plant in the chain of hydropower plants on the Vakhsh river, 110 km away from Dushanbe. The plant will include 6 units 600 MW each.
The dam will be 335 m high. The Rogun hydropower plant will have 3,600 MW capacity (over 17 billion kWh), making it the biggest in the region.
The first unit of the Rogun hydropower plant is expected to be launched at the end of this year.


The project execution committee chairman, Juma Idd declared that preparations for the proposed 2,100MW Rufiji hydropower plant at Stiegler’s Gorge are well underway in order for construction works to commence.

This paper introduces a proposal for reservoir volume calculation in rainwater harvesting systems. The proposed method can be used for reservoir volume design in rainwater harvesting systems and is based on three important variables. These variables are water demand, system efficiency and repayment time. Several simulations were carried out in different scenarios considering typical values of both catchment area (for low-income and medium-income households) and water demand, with fixed water and tank costs. Results showed that the integrated analysis of demand, efficiency and repayment time may assist designers to determine a more adequate reservoir volume.

Construction has officially began on a US$3.7 billion dam in southwest China, AP reported. The Xiangjiaba dam is a 6-gigawatt project on the upper reaches of the Yangtze that will displace between 88,000 to 150,000 people, according to state media. Construction formally began Sunday and is expected to be completed by 2015. China plans to build a dozen hydropower stations along the river's upper stages despite criticism about the environmental and social impact of such projects. Hydroelectric power, however, is relatively clean compared to coal-fired plants, which are currently the main source of energy in China. Xiangjiaba and the nearby 12.6 gigawatt Xiluodu dam will combine to produce more power than the Three Gorges dam.


Jul 25, 2019: With increased water level in Tarbela reservoir and enhanced river flows, the Tarbela 4th Extension Hydropower Project Thursday attained its maximum installed generation capacity by contributing 1410 MW to the National Grid. This power generation reflects the efficiency standards of the power plant.
Meanwhile, Chairman of Water and Power Development Authority (WAPDA), Lt Gen Muzammil Hussain (Retd) congratulated the Tarbela 4th Extension Hydropower Project authorities, the engineers in particular on this professional high mark of efficiency.
The international financial institutions have termed Tarbela 4th Extension as the flagship project of WAPDA. This project went into operation with commissioning of its first unit in February 2018, followed by completion of its second and third units in a phased manner by mid 2018. Since its commissioning, Tarbela 4th Extension Hydropower Project has so far contributed 3.14 billion units of low-cost hydel electricity to the National Grid. This vital project has been instrumental in mitigating power shortages in the country, a press release said.
Tarbela 4th Extension Hydropower Project has been constructed on Tunnel No. 4 of Tarbela Dam. The Project has three generating units, each of them having capacity of 470 MW. The project has been designed to provide 3.84 billion units of electricity on the average to the National Grid per annum. Annual benefits of the project have been estimated at Rs 30 billion. With completion of Tarbela 4th Extension Hydropower Project, the installed capacity of Tarbela Hydel Power Station has increased from 3478 MW to 4888 MW.


Backed by solid academic achievements, Ammar has become a recognized hydrological, hydraulic and dam engineering expert. He has taken part in major European research projects and published articles in international journals. With more than 25 years of practical experience, he has been involved in the design and refurbishment of hydraulic structures, dams, and hydroelectric power plants, as part of various surface water and river flow drainage projects.
Ammar also specializes in the analysis of natural hydrological and hydraulic phenomena using digital modeling systems. His work on a number of Canadian projects includes the determination of benchmark flood levels and flood plains, hydraulic analysis for bridge design, ice and permafrost analysis, and riverbank protection design. In addition, his expertise includes the design of canals, dykes, and hydraulic structures for a number of clients, including Hydro-Québec, Ontario Power Generation, Yukon Energy Corporation, Northwest Territories Power Corporation, BC Hydro, etc.
Some of his most notable accomplishments include the implementation of control gates of all kinds (radial, vertical, timber, inflatable, stoplogs, etc.), wooden, earthfill, rockfill, and concrete dams, the rehabilitation of a 150-year-old dam in Ontario; the design of a 150-metre-high RCC dam, the safety review of a 32-metre-high embankment, a 6-kilometre-long dyke, and a 1- kilometre-long supply tunnel.


DCE were engaged to carry out the detailed design of the civil infrastructure including the tendering and project management of all the civil works. DCE's brief also included the tendering and project management of the demolition and clearing of the extensive existing improvements on the site.
The existing council drainage system was inadequate to cater for the new development with the abutting Lloyd Street regularly flooded in high rainfall events. DCE overcame this constraint by designing an on-site retention system which comprised of a combination of the new internal piped drainage network and a dedicated underground tank with a controlled outlet into the existing Lloyd Street drainage network. The system was designed using Infoworks a dynamic hydraulic modelling software package.

Abstract: The physical model investigation of the West Closure Complex (WCC) Pump Station evaluated flow leaving the 1740 cfs pumps through the flowerpot discharge outlet (FPDO). The model study evaluated stability of flow in the FPDO, head loss through the FPDO to use in pump head estimation, downstream riprap stability, and performance of keel coolers both inside the FPDO and downstream of the FPDO in the tailwater. The recommended Type 8 Design FPDO has a 14-in. wide rounded lip with its top located at elevation (el) 14, the chamber floor at el 11, and the roof at el 23. The diameter of the outlet at the top of the semicircular lip at el 14 was 169.5 in. Two 3-ft wide piers at the downstream end of the chamber were found to not have adverse effects on pump head or flow exiting the chamber. Pressures measured in the pump column and dye injections in the flowerpot section showed stable flow conditions in the vertical column above the pump. Water levels in the chamber were well below the roof and should allow air bulking of the flow without filling of the chamber.
