The Sardar Sarovar Dam is a dam on the Narmada River near Navagam, Gujarat, India. The dam is the largest dam in and part of the Narmada Valley Project, a large hydraulic engineering project involving the construction of a series of large irrigation and hydroelectric multi purpose dams on the Narmada River. The project only took form in 1979 as part of a development scheme to increase irrigation and produce hydroelectricity. The project has the potential to feed as many as 20 million people, provide domestic and industrial water for about 30 million, employ about 1 million, and provide valuable peak electric power in an area with high unmet power demand (farm pumps often get only a few hours power per day). In addition, recent research shows substantial economic multiplier effects (investment and employment triggered by development) from irrigation development.
The cancellation shows the Dam.

The Ministry of Primary Industries said dredging works and the removal of silt and sand forming in the Navua delta would allow for increased flow capacity.
Colonel Mason Smith, the permanent secretary, said: “The total proposed length of the dredge channel is 3.39 kilometres of which 1.59 kilometres will be inland and 1.80 kilometres will be offshore.”
MPI confirmed in a statement the project was being carried out by China Railway First Group Limited for $4,000,000 and expected to be completed in six months.
“Once the dredging work is completed, it is expected that approximately 500,000m3 of dredged material will be removed from the river which will be dumped at four different dump sites alongside the Navua River,” Smith concluded.

The final stage of the $73 million Frankston Drainage Improvement project has been completed.
“This project began in 2009 to improve the level of flood protection for local homes and businesses, and I am pleased to announce its completion today,” said Inga Peulich, Member for South Eastern Metropolitan Region.
“Frankston is one of Melbourne’s lowest-lying areas and was historically subject to serious flooding during severe wet weather.
“By improving the drainage in the area, we can better protect the Frankston central business district and local homes from being flooded.”
The project was completed in three stages and involved the construction of new drainage infrastructure as well as upgrades to the existing system.
VIC Minister for Water Peter Walsh said it was the largest and most complex flood mitigation project ever undertaken by Melbourne Water.
“As well as improving flood protection, several structures were built to improve the quality of stormwater before it enters rivers, creeks and the Bay,” Mr Walsh said.
“This included a pollutant trap and 12 raingardens, which filter stormwater before it flows into waterways.”
Minor works to close out the project, such as land reinstatement, will be completed by mid-December.
The Frankston Drainage Improvement project was delivered by Melbourne Water’s Pipelines Alliance, a partnership between Melbourne Water, Fulton Hogan, Jaydo, and GHD.

Butterley Reservoir is a reservoir in Derbyshire, England. The reservoir was built to provide water for the Cromford Canal which opened for use in 1794. The Codnor Park and Butterley Park reservoirs also provided water to the Cromford Canal. The currently disused Cromford Canal passes beneath the reservoir along the Butterley Tunnel. When the canal tunnel was in use water was provided to the canal directly from the reservoir via an adit which connects to the Butterley tunnel.

MASERU – The Lesotho Highlands Development Authority (LHDA) has launched procurement processes for two major bridges, marking the last step in the procurement of Phase II major works construction.
Tenders for the construction of the Mabunyaneng and Khubelu bridges under Phase II of the Lesotho Highlands Water Project (LHWP) were advertised on Thursday last week. The procurement for the two smaller bridges follows the tender for the biggest of the three Phase II major bridges, the Senqu River Bridge in March this year.
“Procurement for the construction of the two bridges construction also follows the start of the Polihali transfer tunnel and Polihali Dam construction tenders in May and August respectively. It marks the last step in the procurement of Phase II major works construction,” LHDA’s Division Manager Ntsoli Maiketso said in a statement.
Maiketso added that each of the tenders is another step on LHDA’s journey to deliver Phase II of the LHWP on behalf of the government of Lesotho and South Africa as well as advance the economies of the two countries.
The new Khubelu and Mabunyaneng River bridges will be located upstream of the two existing bridges along the A1 road to provide access to Mokhotlong town across the two bridges. The construction of the major bridges will be carried out under two separate contracts.
Phase II of the LHWP builds on the successful completion of Phase I in 2003. It delivers water to Gauteng region of South Africa and utilizes the water delivery system to generate hydroelectricity in Lesotho.
The major works of Phase I included the construction of the Katse Dam, the transfer and delivery tunnels, Matsoku Weir, Muela Hydropwer 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.


ポンプ性能に及ぼす後縁翼の影響 The Influence of Attachments to Blade Trailing Edges on Pump Performance
This papaer reports on an innovative method of changing a centrifugal low specific speed pump performance by applying exit blade flaps to impeller outlet. Centrifugal pump is designed to a specification associated with the maximum impeller diameter. Therefore, when higher head is demanded, a large impeller diameter will be required. Another method to modify pump performance is the formation of flaps at impeller blade exits. The exit blade edge section corresponds to the trailing edge of wing on the circular-cascade, which dominates the pump performance and pressure fluctuation. This paper presents an analytical method of predicting the pump performance related to the attachment of a flap at the trailing edge of impeller outlet. The influence of the flaps on the pressure fluctuation is explained by introducing Kurtosis of flow velocity distribution.

A milestone for the Three Gorges8 October 1998
The condition of the Yangtze river has been of life-threatening importance this year, as it has been the source of massive flooding. The Three Gorges dam project is intended, among other things, to reduce the danger from flooding: Rushu Wang* offers an update on the project
The river diversion is the key point in the construction of any water resources project. At the Three Gorges Project (TGP) on China’s Yangtze river, the river diversion is being accomplished in phases.
The total duration of the project construction is planned at around 17 years, taking account of the time required for preparation. The river diversion is divided into three stages, which are scheduled as follows:
•Preparation period and stage I construction — five years (1993-1997).
•Stage II construction — six years (1998-2003).
•Stage III construction — six years (2004-2009).
In the first stage, now completed, the sub-river on the right side of the islet was closed, the open diversion channel was completed and the longitudinal cofferdam (roller compacted concrete — RCC) was constructed in the pit. The temporary shiplock was finished on the left bank of the river.
During this period, river flow and navigation continued to pass along the original main river course.
In the second stage, construction will be started. The stage II transverse cofferdam will be built up on both the upstream and downstream sides. Together with the completed RCC longitudinal cofferdam, they will form the stage II construction pit. In addition the spillway, the intake dam and the power plant on the left bank will be undergoing construction. Simultaneously, the permanent shiplock and shiplift will be constructed on the left bank.
During this stage river flow will be diverted through the open channel; barge fleets and passenger vessels will be able to pass through either the open channel or the temporary shiplock.
In the third stage, the upstream stage III RCC cofferdam will be built to cut off the open channel and raise the reservoir to 135m in elevation. The left bank power station and permanent shiplock will be put into operation in this phase, as will the stage III construction pit which will make it possible to build the right bank dam and power plant.
During this period, the river flow will be discharged through the permanent bottom outlets and the temporary diversion outlets in the spillway, while boats will pass through the permanent shiplock.
Closure of the Yangtze
The closure of the Yangtze was completed on 8 November 1997.
This milestone marks the successful completion of the stage I works and the beginning of the stage II works. Achieving this milestone was no small task: the design closure discharge is 14000-19400m3/s and the maximum water depth reaches 60m.
The closure dike is located on the downstream side of the stage II upstream cofferdam. Work on the dike began on October 1996, after that year’s flood season, and the gap in the upstream dike had reached 460m by the time of the flood season in 1997. Closure of the gap began on 26 October. The final closure began at 9:00am on 8 November 1998 and was completed at 3:30pm in the afternoon.
The phased closure time was based on a reliable short-term hydrological forecast, the navigation of the Yangtze river and the sediment scouring in the open diversion channel on the right bank.
The stage II cofferdam
The stage II earth-rock cofferdam is located on the left bank of the main river bed. This cofferdam is the most important temporary water-retaining structure of the TGP and the key item in ensuring the safe construction of the main stage II works in the dry pit, and hence the power generation from the first units.
The design standard of the upstream cofferdam is a 100-year flood, with a discharge of 83,700m3/s. The maximum allowed is a once in 200-year flood with discharge of 88,400m3/s. The total length of the upstream and downstream transverse cofferdam is 2438m in axis. It has an earth and rock fill of 10.32M m3 and impervious area of 92,200m2, of which the concrete cut-off wall is 83,450m2. Its maximum height is 74m. As regards the stage II cofferdam, there is a large amount of difficult work to be undertaken during a short timescale. The main technical characteristics of the cofferdam are given in the Table below.
According to the construction schedule for the stage II cofferdam, the single cut-off wall was formed in April and finished in July 1998. The cofferdam was filled to flood control elevation before the flood season in June, and it was also in that month that limited pumping from the pit began. At the time of writing (July) three peak floods in the early part of the month have been met successfully. Preparations are being made for higher floods.


Aecon-EBC General Partnership has been awarded the civil works contract for B.C. Hydro’s John Hart Dam seismic upgrading project near Campbell River.
Construction on the dam is scheduled to begin in the summer of 2023, following the wrap-up of the B.C. Utilities Commission’s vetting of the plan in the spring.
Work on the 2,624-foot-long dam is expected to continue through 2026. The partnership has previous experience constructing and upgrading hydro-electric projects, Stephen Watson, B.C. Hydro spokesman, said Thursday.
The project is being carried out to make sure the dam, built in the 1940s, is able to deliver safe and reliable power and is improved to address safety risks and to significantly increase its ability to withstand a major earthquake.
It will also make the existing spillway gate system more reliable and boost the dam’s capacity.
The earthfill and concrete sections of the dam will be enhanced. A new overflow spillway under the existing road will be constructed as well.
A request for proposals is expected to be issued in 2024 for the hydro-mechanical component of the job, which will start after the civil work is finished. That contract will see three spillway gates and other related work carried out.
The entire cost of the dam work has been estimated at between $497 million and $882 million.
Early site preparation has been going on since September to prepare the land.
Power lines have been relocated and sites have been developed to store materials. A new B.C. Hydro boat ramp, for project personnel only, will be located outside of a planned double silt curtain that will go into the reservoir to preserve water quality as the project unfolds.
Brewster Lake Road has been closed across the dam until Dec. 19 to allow for construction work.
Once construction gets underway in the summer, about 100 people will be on the job daily for the six years of work.
The dam improvements follow the John Hart generating station replacement project, which concluded in 2018.
B.C. Hydro is also planning seismic upgrading to its Ladore and Strathcona dams, which are also in the Campbell River system.

South Para Reservoir Modification
Modifications to the South Para Reservoir dam wall and spillway are proposed that will increase the mitigation capability of the reservoir. This will have the affect of reducing the flow in the Gawler River for major storm events.
The proposal is to raise the dam wall by 1.0 metre and raise the spillway by 1.57 metres but include a 10 metre wide slot. These modifications would have the effect of constructing a flood control storage on top of the full storage level of the reservoir. A paper presented to the ANCOLD 2005 Conference that describes a risk assessment approach to upgrading the reservoir and undertaking the proposed modifications can be downloaded from this page. Construction of these works will be undertaken at a cost to the Scheme by SA Water, possibly in conjunction with dam safety upgrading, and is planned to be completed by July 2010.

Numerical fluid flow modelling and its seismic response in time-lapse
Vanja Milicevic, Robert James Ferguson
A timelapse reservoir characterization study is performed on a model of a producing reservoir. This model reservoir has two injection wells and one producer. Pressure and saturation models are obtained from numerical simulation of reservoir properties and fluid flow for a number of calendar days. Integration of saturation models and Gassmann's relations delivers compressional wave velocity models for each calendar day, and finitedifference algorithms are used to generate synthetic data for comparison; specifically, we compare 2D acoustic and 3C-3D elastic forward modelling. Examples show subtle similarities and differences between the models. Both, acoustic and elastic, models prove to be valuable tools in reservoir characterization.

Stormwater Harvesting Benefits
Stormwater harvesting utilizes a free resource to reduce municipal water supply costs, while complying with regional stormwater management guidelines. In southern climates, a no infiltration system (complete with liner) can be used as the long term storage reservoir, with the water being used for irrigation, washing, or other non-potable applications.
An integrated control system, which include water harvesting information is typically used to operate these harvesting systems. In addition, where the PICP is also serving a stormwater collection system, it is recommended that an active control system be used to monitor weather forecast information and to automatically draw down the water volume to accommodate projected precipitation rates.
How Does a PICP Stormwater Runoff System Store Water?
A Permeable Interlocking Concrete Pavement (PICP) stormwater runoff system stores water by allowing stormwater runoff to infiltrate through porous surfaces into a storage reservoir.

Finance agreement is for construction of world’s largest reinforced concrete water reservoirs
Doha Bank has signed a project finance deal with Leighton Contracting Qatar, a subsidiary of UAE-based Habtoor Leighton Group, for the construction of a water reservoir project valued at $604.1 million (QR2.2bn).
The financing agreement will support the construction of the Qatar General Electricity & Water Corporation’s (Kahramaa) Water Security Mega Reservoirs Project at Rawdat Rashed.
The reservoirs, with a capacity of 100 million gallons each, will be the world’s largest reinforced concrete reservoirs, according to a company statement.
“We are pleased at the opportunity to participate in a project that will form the bedrock upon which Qatar’s water security initiatives will be built,” said Dr R. Seetharaman, Group CEO of Doha Bank. The bank has already issued project-related guarantees, he added.
The Water Security Mega Reservoirs Project was launched in response to a huge increase in the demand for potable water in Qatar. It aims to provide seven days of strategic water storage within Kahramaa’s network, covering the new mega reservoirs as well as the existing and future secondary reservoirs.
According to Kahramaa, the project entails construction of five potable water mega reservoirs sites and an interconnecting network of large-diameter water pipelines. Each reservoir site will contain up to nine reservoirs.
The first phase of the project, which is currently under implementation, will deliver a storage capacity of about 2,300 million gallons of water in 24 concrete reservoirs, and some 480km of buried ductile iron pipelines up to 1.6m in diameter. Meanwhile, the second stage of the project, to be implemented after 2020, will include construction of additional pipelines and 16 new reservoirs within the 5 mega sites, in order to achieve an ultimate total storage capacity of about 3,800 million gallons of water.


Distinguish, differentiate, compare and explain what is the difference between impulse and reaction turbine. Comparison and Differences.
Comparison and Difference between Impulse and Reaction Turbine
1. Impulse turbine works on the principle of impulse while Reaction turbine works on the principle of reaction i.e. backward force developed opposite to a certain action.
2. In impulse, the energy available at the inlet is only kinetic energy and the pressure is atmospheric. In reaction, the energy available at the inlet is both kinetic energy and pressure energy.
3. In an impulse, water flows along the tangent of the runner. Thus it is called tangential flow. In reaction, water flows in the radial direction through the runner. Thus it is called radial flow.
4. The impulse turbine is used for high heads ranging from 150 to 2000 m. The total head of the reaction turbine ranges from about 30 to 500 m.
5. It is possible to regulate the flow without loss in impulse turbine where as in reaction, it is not possible to regulate the flow without loss.

The Miljacka hydroelectric power plant
The Miljacka hydroelectric power plant is the largest hydroelectric power plant on the Krka River, and at the time of its construction it was one of the most powerful hydroelectric power plants in Europe.
Due to large production and exports, and insufficient quantities of electricity, the management of the SUFID factory decided to build a new hydroelectric power plant in the upper course of the Krka at the foot of the Manojlovac waterfall. After many years of preparatory work and changes to the concession holders, work on the construction of a new hydroelectric power plant began in 1903, and on December 12, 1906, the power plant received an operating permit. It entered regular stable operation in early 1907. The water from Brljan Lake was brought to the power plant through a 1588 m long tunnel, with a water drop of 107.3 m, and the available amount was 16 m3/s. Four turbines with a capacity of 24,000 hp and a voltage of 30,000 V were installed. The power plant was connected to the factory in Šibenik by a 34.5 km long transmission line. The total investment in this power plant and transmission line amounted to 6,820,000 Austrian gold crowns, with a concession duration contract of forty years.

Wahl, Tony L.; Cohen, Elisabeth A.. 1999. "Determination of Controlled-Release Capacity from Trinity Dam". Bureau of Reclamation, Report Number PAP-830.
Abstract: Recent studies of alternatives for restoring anadromous fisheries on the Trinity River have recommended increased releases from Trinity Dam. To support these recommendations, the river outlet works, powerplant, and auxiliary outlet works at Trinity Dam were analyzed to determine the maximum possible controlled release. This analysis used a mathematical model of the combined operation of the river outlet works and powerplant, which share a common tunnel and penstock system; previously, the capacity of these components had only been analyzed for their separate operation. The model was calibrated using data collected from two field tests. The result of the analysis is a new set of discharge curves for the Trinity Dam outlet works and powerplant system. Curves have been developed for separate operation of the river outlet works and for combined operation of the outlet works and powerplant, using either the low-head or high-head turbine runners.

Groundwater Dynamics Analysis of Sanmashan Side Slope in the Three Gorges Reservoir Region, China
Sanmashan side slope in the Three Gorges reservoir region is located in the center area of the Xincheng district, Fengjie county, China. Based on the analysis of hydrogeological structure of the studied area, one can conclude that a groundwater reservoir form near the side slope area after the impoundment of the Three Gorges Reservoir, which induces large groundwater pressure on the side slope. In particular, large hydrodynamic pressure will occur in the landslide mass under the condition of the reservoir water level descending significantly, which has bad effects on slope stability. Numerical simulation results show that the seepage force on landslide is 43 times of that under normal situation, as the reservoir water level declining dramatically from 175m to 145m. Thus, the influence of hydrodynamic pressure should be considered in the stability calculation.

Wuhan University of Technology
In order to study the influence of the volute section shape on the performance of naval centrifugal pump as the theoretical basis for the subsequent research on the noise and vibration characteristics of naval centrifugal pump. Under the premise of ensuring the base circle of the volute, the area of the first eight sections, the outlet position of the volute, the outlet diameter of the volute and the center height are the same, the section shape of the volute is changed, and three volute types of A, B and C are designed respectively. The centrifugal pump was numerically calculated with clear water as the medium. The results show that the external characteristics of the centrifugal pump of the three types of volute are basically the same. The efficiency of type A volute centrifugal pump is slightly smaller under the condition of low flow rate, while that of type B and C volute centrifugal pump is small under the condition of large flow rate. With the increase of flow rate, the efficiency of type B and C centrifugal pump decreases greatly. The static pressure distribution, streamline distribution, velocity distribution, turbulent kinetic energy distribution and gas volume fraction distribution trend of the three types of volute centrifugal pumps under the same working conditions are roughly the same. The change of the passage near the impeller tongue is different from that in the volute passage, which indicates that the change of the volute section shape mainly affects the flow field at the impeller outlet and the volute channel.
