1. How a check valve works?
The check valve is one kind of valve which automatically opens and closes the disc driven by the flow of the medium to prevent the medium from flowing back. The check valve is also called as non return valve, cut off valve, one way valve, backwater valve.
The check valve works automatically. Under the action of the fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the fluid pressure and the self-weight of the disc will work on the disc to close to the valve seat, thereby cutting off the flow.
2. What is check valve used for?
The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the leakage of the medium in the container. Check valves may also be used on pipe lines supplying auxiliary systems where the pressure may rise above the system pressure. The check valves can be mainly divided into swing check valve(which rotates according to the center of gravity) and lift check valve(which moves along the axis line).
3. How to inspect a check valve?
The test status of the check valve: the axis of the lift check valve disc is in a position perpendicular to the horizontal; the axis of the swing check valve channel and the disc axis are in a position approximately parallel to the horizontal line.
When testing the strength of the check valve, the test medium is leaded from the inlet end to the specified value, and the other end is closed, to check whether the valve body and the bonnet are leaking or not, if there is no leaking, it is qualified.
For the sealing test of the check valve, the test medium is introduced from the outlet end, check the sealing surface at the inlet end, if there is no leakage on the packing and gasket area, it is qualified.

|Construction cost||CNY¥ 7.64 billion (US$1.2 billion)|
|Pumped-storage power station|
|Upper reservoir||Liyang Upper|
|Upper res. capacity||14,105,000 m3 (11,435 acre·ft)|
|Lower reservoir||Shahe Reservoir|
|Pump-generators||6 x 250 MW Francis pump-turbines|
|Nameplate capacity||1,500 MW|
|Annual output||2.007 billion kWh|
The Liyang Pumped Storage Power Station is a pumped-storage hydroelectric power station 22 km (14 mi) south of Liyang in Jiangsu Province, eastern China. Preliminary construction began in 2002 and major works started in May 2011. The first unit of the power station was commissioned in 2017, the power station will have an installed capacity of 1,500 MW.
As a pumped-storage scheme, the power station shifts water between an upper and a lower reservoir. During periods of low energy demand, when electricity is cheap, the power plant can pump water from the lower reservoir to the upper. When energy demand is high, water is released back down to the power station to produce electricity. The power station will contain six 250 MW reversible Francis pump-turbines which serve to both pump water and generate electricity. The upper reservoir will be formed by a 165 m (541 ft) tall concrete-face rock-fill dam and withhold 14,105,000 m3 (11,435 acre·ft) of water. Of that capacity, 12,100,000 m3 (9,810 acre·ft) is active (or usable) storage for power generation. The lower reservoir will be formed adjacent to the Shahe Reservoir with a series of dikes. The power station will generation an estimated 2.007 billion kWh annually and consume 2.676 billion kWh when pumping. Although the power station will consume more energy than it will produce, it is economical because pumping occurs when electricity is cheaper.

Check valve is a kind of valve whose opening and closing parts are round disc and whose action is generated by its own weight and medium pressure to block the backflow of medium. It belongs to automatic valve, also known as check valve, return valve or isolation valve. The check valve is an automatic valve, and its main function is to prevent the medium from flowing backward, to prevent the pump and the drive motor from reversing, and to release the container medium.
Check valve can be divided into three types: swing check valve, lift check valve, disc check valve, pipeline check valve and pressure check valve according to its structure and installation. Let's talk about their installation in detail.
The disc of the swing check valve is in the shape of a disc, rotating around the shaft of the valve seat channel. Because the internal channel of the valve is streamlined, the flow resistance is smaller than that of the lift check valve. It is suitable for low flow rate and large caliber occasions with little flow change, but it is not suitable for pulsating flow, and its sealing performance is inferior to that of the lift check valve. The swing check valve is divided into three types, single disc type, double disc type and multi half type. These three types are mainly divided according to the valve diameter. The purpose is to prevent the hydraulic impact when the medium stops flowing or flows backward.
It is a check valve with the disc sliding along the vertical centerline of the valve body. Lift check valve can only be installed on the horizontal pipeline, and the disc can be a ball on the high-pressure small caliber check valve. The body shape of lift check valve is the same as that of stop valve (It can be used in common with stop valve), so its fluid resistance coefficient is large. Its structure is similar to the stop valve, and the valve body and disc are the same as the stop valve. The upper part of the disc and the lower part of the bonnet are processed with a guide sleeve. The guide sleeve of the disc can freely rise and fall in the guide sleeve of the disc. When the medium flows in the same direction, the disc is opened by the medium thrust. When the medium stops flowing, the disc falls on the valve seat by the self suspension, which plays a role in preventing the medium reverse flow. The direction of medium inlet and outlet channel of straight lift check valve is perpendicular to that of valve seat channel. The direction of medium inlet and outlet channel of vertical lift check valve is the same as that of valve seat channel, and its flow resistance is smaller than that of straight lift check valve.
Its disc rotates around the pin shaft in the valve seat. The disc check valve is simple in structure and can only be installed on the horizontal pipeline with poor sealing performance.
Its disc slides along the center line of the valve body. Pipeline check valve is a new kind of valve. It has small volume, light weight and good processing technology, which is one of the development directions of check valve. However, the fluid resistance coefficient is slightly larger than that of swing check valve.
This valve is used for boiler feed water and steam cut-off. It has the comprehensive functions of lift check valve, stop valve or angle valve.
In addition, there are some check valves that are not suitable for pump outlet installation, such as bottom valve, spring type, Y type, etc.
① Do not allow the check valve to bear the weight in the pipeline system. The large check valve shall be supported independently, so that it is not affected by the pressure generated by the pipeline system.
② During installation, the direction of medium flow shall be consistent with the direction of arrow marked on the valve body.
③ Lift type vertical disc check valve shall be installed on the vertical pipeline.
④ The lift horizontal disc check valve shall be installed on the horizontal pipeline.
The reason for the disc breaking is that the medium pressure before and after the check valve is in a state of close balance and mutual "sawing". The disc often beats with the valve seat, and the disc made of some brittle materials (such as cast iron, brass, etc.) is broken. The prevention method is to use the check valve with the disc made of ductile materials.
The reasons for the backflow of media are two types.
① The sealing surface is damaged.
② Impurities are entrained.
Repairing the sealing surface and cleaning impurities can prevent backflow.

Erbil Governorate, Autonomous Region of Kurdistan, Iraq
Proposed hydraulic works downstream of the designed dam Bastora are located in the valley of the same name, a tributary of the Greater Zab River.
Administrative, the sites of the weirs are located in Erbil governorate, the limit of Shaqlawa districts and Dashti Hawler Erbil.
These works consist of 5 small overflow weirs mainly intended for raising the groundwater level in the area.
The water storage will provide water, for different purposes during the drought season:
– Irrigation possibility for agriculture land
– Water supply by raising the underground level.
In the pre-feasibility study were analyzed two locations for each weir and 3 solution for the execution of the weirs:
1. Weir made out of Rockfill concrete impervious with a concrete mask
2. Weir made out of Rockfill concrete impervious with a geo-membrane mask
3. Concrete gravity type.
The final approved solution of weirs type: concrete gravity.
Considering the Hydrological Study and follow-up of the beneficiary’s investment advice, methods of execution of works, and those in the process of execution, but also the needs of similar experience in Kurdistan, it was considered only discharge free version without the use of the hydro-mechanical equipment.
The spillway dam with free level of overflowing is the optimum choice for maximum safety utilization.
It has to be mentioned that it was considered the unreinforced concrete and reinforced concrete to be used for the construction of the weirs, as the most corresponding and efficient solution, observing the small dimensions of the dams and the geological and geotechnical background.

عنوان مقاله [English]
In this study,, two Ogee Spillways with elliptical crest and USBR were simulated in both vertical upstream face state and inclined one with slope 3H:3V for three different heads He / Hd = 0.5, He / Hd = 1 and He / Hd = 1.33. and the results of changes in effective parameters such as flow rate, velocity and pressure were evaluated.
In this study, the results of Maynard’s Experimental model have been used to simulation and validate numerical results. The average errors of computed discharge compared with Maynard’s experimental data were less than 3%. Evaluation of the pressure field showed that at the head equal to the design head (He / Hd = 1), the pressures are close to atmospheric pressure and no negative pressure is created on the ogee crest, but at the head more than the design head there will be negative pressure on the overflow. the study of the pressure field showed that the amount of negative pressure in the USBR crest is higher than the amount of negative pressure in the elliptical crest, which is due to the lack of coherence in the crest and more separation of flow lines from it. The Ogee spillway with the elliptical crest has a relatively better performance in passing the flow and in these spillways, it is possible to pass more discharge with higher safety. Also inclining upstream face of spillway causes a change in the discharge coefficient and finally the flow rate through the spillway.

Keywords: Waterhammer; pipeline system; cavitation; two dimensional model; energy transition
Abstract: A waterhammer model was proposed to simulate a transient event with cavitation in a simple pipeline system. The governing equations for a quasi-two-dimensional model were solved through a hybrid scheme of the method of characteristics and the finite difference method considering the relationship between pressure head reduction and cavitation. An alternative method to address the boundary condition for the two-dimensional model was proposed, which improved the stability of the existing approaches. The comparison of longitudinal and radial velocity profiles between the proposed and existing models exhibited significant differences, which can be explained by the sequential generation and collapse of the cavity. The time series of the pressure head obtained through experimental transient events with vapour cavitation showed good agreement with that of the proposed model. The investigation of energy under a waterhammer showed that the pattern of transition between internal energy and kinetic energy is also substantially affected by the fate of cavitation during transient events.

The Moragahakanda Dam is a high gravity dam with a height of 65 meters. The dam has created the Moragahakanda Reservoir, which has an active storage capacity of 521,000,000 cubic meters, and is four times bigger than the gigantic Parakrama Samudraya in Polonnaruwa.
Two additional embankment saddle dams have been built to contain the Moragahakanda Reservoir. The reservoir of the Kalu Ganga Dam has been linked via a tunnel.
Water from both, the Moragahakanda and Kalu Ganga reservoirs, will be primarily used to support agricultural needs in an area of at least 81,422 hectares. This would increase rice production by 81% or 109,000 tons, amounting to an estimated monetary benefit of US$1.67 million, annually.
In addition to the irrigation of land, water from the Moragahakanda Reservoir will be used to power the 25-megawatt Moragahakanda Hydroelectric Power Station.
Prior to Moragahakanda, all other projects under the Mahaweli have been completed.
They include the Victoria Dam, located across the Mahaweli Ganga immediately upstream of the Victoria Falls rapids about 130 miles from the river mouth; the Randenigala Project, the fourth major multi-purpose project and the largest reservoir under the Accelerated Mahaweli Development Program; the Rantambe Dam and power station form the most downstream project of a cascade of reservoirs and hydro power stations on the Mahaweli Ganga in the Dumbara Valley; the Polgolla project, which carried water resources of the Mahaweli Ganga Basin; the Kotmale project, which is one of five major head works projects undertaken under the Accelerated Mahaweli Ganga scheme; and the Bowatenne Diversion Project, which lies in the northern part of the central highlands of Sri Lanka.

About Xiluodu Hydropower Plant
The 13.86GW Xiluodu hydroelectric power plant on Jinsha Jiang River, China, was inaugurated in September 2013. It was fully operational in June 2014, becoming the world’s third biggest hydroelectric power plant. The project includes a dam, an underground power-generation unit and a flood discharge structure. It is mainly developed for power generation, and sediment and flood control while also improving the downstream navigation of the river. Xiluodu power plant offsets approximately 150m tonnes of carbon dioxide emissions a year. It reduces the consumption of 41 million tonnes of coal for electricity generation. However, the project displaced approximately 180,000 people.
The Three Gorges Project Corporation, which developed China’s biggest hydropower plant Three Gorges, also developed the Xiluodu power plant. The Xiluodu plant generates 64bkWh of electricity a year.
About Xiluodu Dam
The Xiluodu Dam is located on the Jinsha (Upper Yangtze) River as it exits the mountainous region of the Hengduan Mountains and Yungui Plateau and enters the Sichuan Basin. This part of the Jinsha flows between the Daliang Mountains in Sichuan on the left (northwest) bank, and the Wulian Feng in Yunnan on the right (southeast) bank. The Jinsha falls to an elevation of 400 m (1,300 ft) above sea level here while mountains rise more than 2,000 m (6,600 ft) above the Jinsha on either side.
The Xiluodu Dam is an arch dam on the Jinsha River, i.e. the upper course of the Yangtze in China. It is located near the town of Xiluodu in Yongshan County of Yunnan Province but the dam straddles into Leibo County of Sichuan Province on the opposite side of the river. The primary purpose of the dam is hydroelectric power generation and its power station has an installed capacity of 13,860 MW. Additionally, the dam provides for flood control, silt control and its regulated water releases are intended to improve navigation downstream. Construction on the dam and power station began in 2005 and the first generator was commissioned in 2013, the last in 2014. It is operated by China Yangtze Power and is currently the third-largest power station with the fourth-tallest dam in the world.
Power transmission from the Xiluodu power plant
The Xiluodu power plant generates roughly 64TWh of power a year. The power is transmitted via the Xiluodu-Zhejiang and Xiluodu-Guangdong overhead transmission lines.
The Xiluodu-Guangdong HVDC project is a double 500-kV bipole system with a transmission capacity of 6,400MW. The power is transferred from Zhaotong station in Xiluodo to Conghua station in Guangdong via 1,286km-long transmission line.
The electricity generated from the left bank power house is sold to State Grid Corporation of China. The electricity from the right bank is sold to China Southern Power Grid. The respective electricity sales contracts were signed in July 2013.


SACRAMENTO, Calif. – The U.S. Army Corps of Engineers Sacramento District approved April 11 raising the operating restriction of the reservoir behind Success Dam to the maximum authorized storage capacity of 82,291 acre-feet, or a storage elevation of 652.5 feet. Ultimately, this could mean more water for local users during high-water months.
“Older dams like Success still have safety concerns and need to be continually inspected and monitored,” said Corps’ project manager, Glen Reed. “But we are confident based on the initial results of our risk assessment, that we can allow more water in the lake without additional risk to the public.”
In late 2006, the Corps began limiting the amount of water stored in Success Lake to minimize flood risk to the public while studying safety concerns at the dam. Initial study results showed that risk associated with seismic activity and seepage is significantly lower than was earlier indicated. The Corps temporarily relaxed the pool restriction to allow more water into the reservoir in 2009, and further relaxed the restriction in 2012.
The U.S. Army Corps of Engineers is conducting a baseline risk assessment for Success Dam - a comprehensive analysis of all the dam’s safety risks - that is scheduled to be completed in summer 2014. When that is approved, the Corps will determine if any fixes are necessary for Success Dam.
Success Dam is located on the Tule River, about five miles east and upstream of the town of Porterville. The dam and reservoir were authorized as part of the Tule River Project under the Flood Control Act of 1944 and construction was completed in 1961. The reservoir provides flood risk management, water storage and recreation benefits to the local area.

The hydropower station, owned by the company KCIA-94, was built in 1935 on the river Dashbashi, in the Tsalka district of Georgia. In 2012 the Dashbashi station was connected to the Tsalka substation through a new transmission line. The HPP had an installed capacity of 1.52 MW with power being generated by three hydraulic units (horizontal shaft Francis turbines and generators).
The old turbines did not fully utilize the hydrological resource of the Dashbashi river (3,500 l/sec) and the company started an investment project to replace one of the outdated turbines and generators, while increasing the station capacity to 3MW. One 550 kW hydraulic unit was replaced against a modern 2,125 kW unit.
the increase in the station’s capacity, financed through a EU4Business-EBRD Credit Line loan, increased the green and clean power generation of the old station without the need to change the diverted flow and without any change to the existing building infrastructure. Furthermore, the new turbines generate less noise and vibration levels.

Management strategies for flood protection in the Lower Illinois River, Phase I: Development of the Lower Illinois River-Pool 26 UNET model
- One of the main concerns was the ability to specify proper stage hydrographs at the downstream boundary of the Lower Illinois River for hydraulic design and analysis. We found that a unique stage-discharge rating relationship does not exist at the lower boundary of the Lower Illinois River at Grafton because of backwater effects from the Upper Mississippi River. Management options and results for managed storage and emergency activities need to be analyzed under more comprehensive design of flooding conditions. To improve the capability of UNET for modeling backwater effects for the Lower Illinois River, an extended model including Pool 26 of the Upper Mississippi River was developed. The downstream stations of the model are at the tail of Lock and Dam 25 and the Mel Price Lock and Dam pool, where stage readings are available. The model was calibrated with a 1979 flood and verified with a 1983 flood. Discharge and stage frequency analysis have also been performed for stations at Troy on Cuivre River, Lock and Dam 25 tail, Lock and Dam 26 pool, and Mel Price Lock and Dam on the Mississippi River.

Project: Expansion of the district cooling network.
Commission: Design and construction management.
Client: Fortum Värme
Fortum is continuously developing the district cooling system in Stockholm. It is already the biggest network in the world with a pipe length of 150 km.
In 2007 Termoekonomi received the order for design and construction management for an expansion in the south part of the network. The total distance from the existing network to the new client was 2.4 km. The route passes the well-known eco-city ”Hammarby Sjöstad”, Sickla channel and a motorway.
The pipes were design for a cooling capacity of 12 MW. We designed for plastic tubes (PE) with dimensions up to PE 400.
We used steered drilling to manage the complicated passings. Totally 700 m is realized with this technique.
The existing pumping capacity had to be increased to manage the extension of the network. Termoekonomi designed a new pump station with two pumps each with 110 kW motors. As for the pipes we also carried out the construction management.


The motor is constructed to lubricate by water, internal filling clean water that cannot Cause water pollution.
Quality is reliable and durable, without complex maintenance, excellent electricity properties and high efficiency. Rugged construction will not be deformed.
Stator outer tube made of stainless steel welding, stainless steel inner lining, high insulation wire and sealed by epoxy provide high insulation, good corrosion resistance, heat radiating good, high pressure resistance for deep well.
Super lower suction level, is not electricity leakage.
Centrifugal impeller design increase pump head
Two sets of mechanical seal and thrust bearings increase anti-wear ability and long life.
Precisely impeller balance calibrate by balancing machine. The pump runs smoothly and silently.
Safety design makes pump with 24 hours continuous operation ability.
Motor shaft directly connect to impeller for the best energy saving.

Weep Hole Design in Water Conveyance Tunnel
Water supply mains and inland ware net-working systems require large scale of water conveyance tunnels. Recently, to control flood and measure drought, 11 km of water conveyance tunnel connecting two earth and rockfill dams was constructed in South Korea. The tunnels are generally located in the mountain areas and constructed as drains. Circular concrete liners without drainage system were installed to prevent from weathering of excavation boundaries and rockfall failure. As deep tunnels, high ground water pressure possibly act on the tunnel linings. To avoid high ground pressure and measure the lining damages, weep holes are installed, which is very costly. To reduce construction cost and efforts, design method to seek the optimal length, arrangement and interval of weep hole was investigated. A numerical parametric study on the design factors such as the number of weep holes, lateral spacing, weep hole diameter, length and longitudinal distance and arrangement are firstly performed, and theoretical evaluation is performed. Based on the analytical study and field experience, a design guidelines on the optimal method of weep hole installation is proposed.

DC Water and Sewer Authority’s long term CSO control plan includes a system of tunnels to control combined sewer overflows into the Anacostia River, Rock Creek, and the Potomac River and transport those captured flows to the Blue Plains Advanced Wastewater Treatment Plant.
The Anacostia River Tunnel is one component of this long-term control plan. The project was completed in late 2017 and has contributed to an increased capacity of the District’s sewer system, significantly mitigating the frequency, magnitude, and duration of sewer flooding. It is also helping to improve the water quality of the Anacostia River.
The project consisted of the final design and construction of the following main components:
- 12,500-foot long 23-foot diameter, reinforced concrete segmentally lined tunnel
- Six shafts with various configurations that include hydraulic internal structures, vortex drop facilities, and diversion chambers
- Two shafts constructed at CSO-019 and connected by an interconnecting tunnel constructed by Sequential Excavation Methods
- Diversion chambers with connecting diversion sewers and approach channels at two shaft locations
- Adit tunnels to connect the shafts to the tunnel at three shaft locations
- Ventilation control facilities to regulate air flow in the tunnel system.

Minnesota weather: Cannon River in Northfield under flood warning
NORTHFIELD, Minn. (FOX 9) - The Cannon River is expected to hit flood stage on Tuesday night, and the rising river level has already caused flooding at Carleton College in Northfield.
The river in Rice and Dakota counties is rising due to melting snow and recent rains. And with more storms on the way, flooding is expected over the next few days. This has prompted a river flood warning for the Cannon River — the first of the year in the region.
The Cannon River runs through the town of Northfield, about 45 minutes south of Minneapolis. Carleton College's campus is on the northeast side of town. There, soccer fields are currently underwater.
The Cannon River in Northfield, Minnesota, is expected to reach flood stage on Tuesday. (FOX 9)
Tuesday morning, the river level was right around 896.5 feet, just a few inches below flood stage. The river will likely hit flood stage by Tuesday afternoon, with levels expected to crest causing minor flooding Wednesday night and then be back down below flood stage by Friday morning.
This isn't the only area seeing flooding. The Zumbro River is also nearing flood stage in Wabasha and Olmsted counties.

ISLAMABAD, Feb 19 (APP): The under-construction Dasu Hydropower Project crossed a major milestone the other day, as the mighty River Indus was successfully diverted following completion of one of the two diversion tunnels.
Instead of its natural course, the River Indus was now flowing through a 1.33 kilometer (km) long diversion tunnel with 20 meters (m) width and 23m height, said a press release.
Consequently, construction activities have been initiated on the starter dam, leading toward the construction of the main dam of Dasu Hydropower Project.
General Manager and Project Director Dasu Hydropower Project, representatives of the Contractors and the Consultants along with a number of engineers and workers witnessed the historic moment of River Indus diversion.
Meanwhile, WAPDA Chairman Engr Lt Gen. Sajjad Ghani (Retd) congratulated the project team on achieving this landmark.
The diversion system of Dasu Hydropower Project comprises two tunnels – tunnel A and tunnel B. Of these, tunnel B is complete, which has the discharge capacity, sufficient to divert water of River Indus during the current lean-flows season, the press release says.
The 1.5 km long tunnel A, with 20m width and 23m height, will also be ready by mid-April this year to cater to the increased water flows during the high-flows season, it adds.
Dasu Hydropower Project is a vital component of the least-cost, green and clean energy generation plan of WAPDA. The project is being constructed across River Indus, upstream of Dasu town in Upper Kohistan district of Khyber Pakhtunkhwa.
The 4320 MW Dasu Hydropower Project is planned to be completed in two stages.
At present, WAPDA is constructing its stage-I with installed generation capacity of 2160 MW and annual energy generation of 12 billion units. Stage-I of the project is likely to start electricity generation in 2026.
The 2160 MW stage-II, when implemented, will also provide 9 billion units to the National Grid. On completion of both stages, Dasu will become the project with the highest annual energy generation in Pakistan i.e., 21 billion units per annum on average.

For past many years while China has been in the news for its efforts in exploiting the vast hydro power potential of Yarlung Tsangpo River of Tibet Autonomous Region India has also been attempting to tap the potential of this river known as Brahmaputra in India.
Recent reports indicate that China has approved the construction of three new hydropower dams on the middle reaches of Yarlung Tsangpo. Work on an older 510 MW hydro project in Zangmu in Tibet had commenced way back in 2010. The capacity of the two new projects coming up at Dagu and Jiacha would be 640 MW and 320 MW respectively while the capacity of the third new dam at Jiexu is yet to be confirmed. These projects have been planned to be completed in China's 12th Five Year Plan period i.e. 2011-2017. China has, as usual, given the assurances that these are run of the river projects and in no way affect the downstream flows. In addition China has also built at least six smaller projects on tributaries of Tsangpo which again according to the Chinese would not affect waters flowing into India READ MORE

Tanahun hydel project construction accelerates
Damauli, June 22
The construction of infrastructure to build the 140 MW Tanahun Hydro Project at Byas Municipality is being accelerated in Tanahun.
Several works are in their final stages, said site in-charge Bidur Adhikari. Bridge construction over the Seti River, setting up camp, black-topping of the road from Chapaghat to Jhaputar and construction of the 300-metre tunnel works have been stepped up.
Similarly, technical and financial study of forms applied for the project’s package No 1 and 2 which were shortlisted from the global tender has started. Global tenders were called in for the construction of a dam site under package 1 and construction of power house under package 2. “The technical and financial assessment will be completed within two months,” said Adhikari.
However, the project is yet to issue the tender for the construction of transmission line under package 3. The estimated budget for the construction of the project is 50 billion rupees. The Government of Nepal will invest 13 billion rupees, while JICA will invest Rs 4 billion, Asian Development Bank Rs 15 billion and European Investment Bank Rs 4 billion for the project.
According to Adhikari, the project is all set to begin its construction from November this year and it is expected to be completed by the stipulated year 2022.
The hydro electricity generated from the project will be distributed through the national transmission line in Bharatpur Sub-station, 36 km from the project site.


As February wanes away and spring approaches the yearly reduction of flow in the lower Assiniboine has begun.
The Hydrologic Forecast Centre of Manitoba Infrastructure has reduced flows out of the Shellmouth Reservoir this week to 90 cubic feet per second (cfs) from 320 cfs. This could make the ice unstable along the Assiniboine River.
As flow from the reservoir decreases voids will form under the river ice. This process seriously reduces the carrying capacity of the ice, causing hazardous conditions for those using the river for travel or recreation.
Each winter the Shellmouth dam operates to maintain the lake and downstream flow at levels that will balance the need for reservoir capacity, recreational use on the lake and the health of fish and wildlife in the system.
Before spring melt, a low flow on the Assiniboine makes room for run-off and spring rains.
The level of the lake has been steadily dropping over the winter, as planned. Current lake levels are at 1397 ft. The target level after spring run-off is 1402 – 1404 ft. above sea level.

The Research Institute of Hydraulic Engineering (RIHE) was founded in 1973. It is equipped with three flumes of different sizes, among them one tilting flume. The capacity of the pumps allows hydraulic experiments and model tests up to a discharge of 300 l/s. Flow velocities can be measured by classic current meters as well as by 3D- ultrasonic probes (3D –ADV) and by particle image velocimetry (PIV). Water depths and pressure are measured by ultrasonic stage gauges and piezo pressure probes.
The research in the RIHE is mainly practically oriented. Research work model tests and field measurements were carried out i.e. on flood protection, flow resistance of flexible vegetation, flow optimization of different hydraulic structures, infiltration of pavement, hydraulic capacity of soil filters, aggradation of sediments at a gauge station. Furthermore the HRL provides demonstrations and practical training within the of civil engineering curriculum and also allows theses with experimental background. Since 2007 a virtual laboratory (ViWaLa) is incorporated in the RIHE.
The Research Institute of Hydraulic Engineering is part of the Faculty of Architecture and Civil Engineering.
