In this paper, the effects of modifying the blade pressure side (PS) on unsteady pressure pulsation and flow structures in a low specific speed centrifugal pump are carried out by experimental and computational fluid dynamics (CFD). Seven monitor points are arranged in the circumferential direction of the impeller outlet to capture the pressure signals in the volute at flow rate of 0.2–1.6Qd. Results show that the blade PS modification introduced here can significantly alleviate the amplitude of pressure pulsation at blade passing frequency (fBPF) in all concerned operation conditions. To study the effects of blade modification on the internal flow field, the volute domain is replaced by an even outlet region for CFD analysis. The shear stress transfer (SST) turbulence model is adopted for steady-state numerical simulation while the delayed detached eddy simulation (DDES) based on the SST approach is adopted for transient simulation. Results show that local unsteady velocity fluctuation is the dominant reason for pressure pulsation in the volute. After blade PS modification, the relative velocity distribution at the impeller outlet is more uniform and the intensity of shedding vortex at the blade trailing edge (TE) decreases significantly. The change of internal flow structure improves the uniformity of circumferential velocity distribution the downstream of the impeller outlet, which leads to the decrease of pressure fluctuation amplitude in the volute. Meanwhile, the local Euler head (LEH) distribution at the impeller outlet and the blade loading of PS are presented and compared. It can be concluded that the reduction of pressure pulsation attributes to a more uniform energy distribution at the impeller outlet which is achieved by actively unloading the PS of the modified blades.


The Federal Government has announced plans to explore adding 2,500 MW of pump storage hydro to Hydro Tasmania’s portfolio. ARENA will contribute $2.5 million towards a study which will explore a replacement of a Central Highlands power station and redeveloping Gordon power station. The study will also examine 13 potential sites for new pumped storage hydro.
The additional pumped storage hydro plant could assist with energy security in times of peak demand. Tasmania currently imports power from Victoria, though with the closure of Hazelwood Power Station prices have increased over the last month. Having additional storage capacity will also allow development of further renewable opportunities in the state.


Historic Hood River
Condit Dam Stereo View
This stereo card view of Condit Dam has lots of interesting detail. It looks like it was taken shortly after the dam’s 1913 construction. Condit Dam was from a very active era of hydroelectric power projects in the area. There were at least three Powerdale projects on the lower Hood River, as well as hydro power at Tucker Bridge, Dee Mill, and White River south of the Dalles.
This dam was removed starting in 2011.


HETAUDA, Dec 17: Prime Minister Pushpa Kamal Dahal has said that chiefs of concerned projects should be more responsible to maintain transparency and quality in course of construction development projects of the country.
Inspecting the power house, reservoir road and turbine of under construction Kulekhani III Hydel Project at Bhaise VDC-6 in Makawanpur district today, Prime Minister Dahal said that the projects should be completed in smooth and easy manner by mobilizing the means and resources provided by the government.
He said that the government was committed to provide budget and technicians required for the construction of the projects, urging the office-bearers of the development projects to move head by eliminating dillydallying and obstruction.
The PM further said that the government would talk with Chinese government to complete the construction works of Kulekhani III Hydro Project soon as the Chinese construction company has been making dillydallying to complete the construction works.
Chief of the Kulekhani III Hydel Project, Subas Mishra, said although the construction works of the project began on December 15, 2012, it delayed due to dillydallying of the construction company.
Mishra said that a goal has been set to complete it by mid-August, 2017.The government has invested Rs 4.63 billion to construct the project.
Mishra told the Rastriya Samachar Samiti (RSS) that 40 MW power per hour will be generated from the project. RSS

Tarbela Dam is a earth fill dam located on the Indus River in Pakistan. It is the largest earth-filled dam in the world and fifth-largest by structural volume. It is named after the town Tarbela, in Khyber Pakhtunkhwa, about 50 kilometres (31 mi) northwest of Islamabad.
The dam is 485 feet (148 m) high above the riverbed. The dam forms the Tarbela Reservoir, with a surface area of approximately 250 square kilometres (97 sq mi). The dam was completed in 1976 and was designed to store water from the Indus River forirrigation, flood control, and the generation of hydroelectric power.
The primary use of the dam is for electricity generation, the installed capacity of the 3,478 MW Tarbela hydroelectric power stations will increase to 6,298MW after completion of the ongoing fourth extension and the planned fifth extension financed by Asian Infrastructure Investment Bank and the World Bank
The project is located at a narrow spot in the Indus River valley, at Tarbela between Haripur District and Swabi District, approximately 60 kilometers northwest of Islamabad.
The main dam wall, built of earth and rock fill, stretches 2,743 metres (8,999 ft) from the island to river right, standing 148 metres (486 ft) high. A pair of concrete auxiliary dams spans the river from the island to river left. The dam's two spillways are located on the auxiliary dams rather than the main dam. The main spillway has a discharge capacity of 18,406 cubic metres per second (650,000 cu ft/s) and the auxiliary spillway, 24,070 cubic metres per second (850,000 cu ft/s). Annually, over 70% of water discharged at Tarbela passes over the spillways, and is not used for hydropower generation.
Five large tunnels were constructed as part of Tarbela Dam's outlet works. Hydroelectricity is generated from turbines in tunnel 1 through 3, while tunnels 4 and 5 were designed for irrigation use, although both tunnels are to be converted to hydropower tunnels to increase Tarbela's electricity generating capacity.These tunnels were originally used to divert the Indus River while the dam was being constructed.
MA hydroelectric power plant on the right side of the main dam houses 14 generators fed with water from outlet tunnels 1, 2, and 3. There are four 175 MW generators on tunnel 1, six 175 MW generators on tunnel 2, and four 432 MW generators on tunnel 3, for a total generating capacity of 3,478 MW.
Tarbela Reservoir is 80.5 kilometres (50.0 mi) long, with a surface area of 250 square kilometres (97 sq mi). The reservoir initially stored 11,600,000 acre feet (14.3 km3) of water, with a live storage of 9,700,000 acre feet (12.0 km3), though this figure has been reduced over the subsequent 35 years of operation to 6,800,000 acre feet (8.4 km3) due to silting.
The catchment area upriver of the Tarbela Dam is spread over 168,000 square kilometres (65,000 sq mi) of land largely supplemented by snow and glacier melt from the southern slopes of the Himalayas. There are two main Indus River tributaries upstream of the Tarbela Dam. These are the Shyok River, joining near Skardu, and the Siran River near Tarbela.
Tarbela dam was constructed as part of the Indus Basin Project after signing of the 1960 Indus Waters Treaty between India and Pakistan. The purpose was to compensate for the loss of water supplies of the eastern rivers (Ravi, Sutlej and Beas) that were designated for exclusive use by India per terms of the Treaty. The primary objective of the dam was to supply water for irrigation by storing flows during the monsoon period and subsequently releasing stored water during the low flow period in winter.
By the mid-1970s, power generation capacity was added in three subsequent hydro-electrical project extensions which were completed in 1992, installing a total of 3,478 MW generating capacity on respectively Tunnel 1 (four turbines), Tunnel 2 (six turbines) and Tunnel 3 (four turbines).
Construction of Tarbela Dam was carried out in three stages to meet the diversion requirements of the river. Construction was undertaken by the Italian firm Salini Impregilo.
In the first stage, the Indus river was allowed to flow in its natural channel, while construction works commenced on the right bank where a 1500 feet (457 meters) long and 694 feet (212 meters) wide diversion channel was being excavated along with a 105 feet (32 meters) high buttress dam that was also being construction. Stage 1 construction lasted approximately 2.5 years.
The main embankment dam and the upstream blanket were constructed across the main valley of the river Indus as part of the second stage of construction. During this time, water from the Indus river remained diverted through the diversion channel. By the end of construction works in stage 2, tunnels had been built for diversion purposes. Stage 2 construction took 3 years to complete.
Under the third stage of construction, works were carried out on the closure of diversion channel and construction of the dam in that portion while the river was made to flow through diversion tunnels. The remaining portion of upstream blanket and the main dam at higher levels was also completed as part of stage 3 works, which were concluded in 1976.
Re-settlement of people affected by Tarbela Dam
It has a reservoir area of about 260 square kilometers and about 82,000 acres (33,000 ha) of land was acquired for its construction. The large reservoir of the dam submerged 135 villages, which resulted in displacement of a population of about 96,000 people, many of whom were relocated to a series of townships surrounding the Tarbela reservoir or in adjacent higher valleys.
For the land and built-up property acquired under the Land Acquisition Act of 1984, a cash compensation of Rs 469.65 million was paid to those affected. In the absence of a national policy, resettlement concerns of the affectees of Tarbela Dam were addressed on an ad hoc basis.
Many affectees of the Tarbela Dam have still not been settled and have not been given land as compensation by the government of Pakistan, in accordance with its contractual obligations with the World Bank. However, some of the affectees have been settled at Khalabat Township and other places across Pakistan.
Because the source of the Indus River is glacial meltwater from the Himalayas, the river carries huge amounts of sediment, with an annual suspended sediment load of 200 million tons.
Live storage capacity of Terbela reservoir had declined more than 33.5 per cent to 6.434 million acre feet (MAF) against its original capacity of 9.679 MAF because of sedimentation over the past 38 years. The useful life of the dam and reservoir was estimated to be approximately fifty years. However, sedimentation has been much lower than predicted, and it is now estimated that the useful lifespan of the dam will be 85 years, to about 2060.
Pakistan also plans to construct several large dams upstream of Tarbela, including the Diamer-Bhasha Dam. Upon completion of the Diamer-Bhasha dam, sediment loads into Tarbela will be decreased by 69%.
In addition to fulfilling the primary purpose of the dam, i.e. supplying water for irrigation, Tarbela Power Station has generated 341.139 billion kWh of cheap hydro-electric energy since commissioning. A record annual generation of 16.463 billion kWh was recorded during 1998–99. Annual generation during 2007–08 was 14.959 billion kWh while the station shared peak load of 3702 MW during the year, which was 23.057% of total WAPDA system peak.
Tarbela-IV Extension Project
In September 2013, Pakistan's Water and Power Development Authority signed a Rs.26.053 billion contract with Chinese firm Sinohydro and Germany's Voith Hydro for executing civil works on the 1,410 MW Tarbela-IV Extension Project. Construction commenced in February 2014, and is expected to be completed by June 2017. Upon completion, the project will augment the Early Harvest Project of the China–Pakistan Economic Corridor.
The project is being constructed at tunnel 4 of the dam which was originally intended for irrigation, but was later taken up for power generation as country’s electricity demand increased. As much of the infrastructure for the project already exists, conversion of the irrigation tunnel into a hydroelectric tunnel was regarded as a cost-effective way to ease Pakistan's energy shortfall.
Annual benefits of the project were estimated at about Rs. 30.7 billion. On an annual basis, over 70% of water passing through Tarbela is discharged over spillways, while only a portion of the remaining 30% is used for hydropower generation.
As of February 2016, the Government of Pakistan states that 49% of works have been completed on the 4th phase extension project.
The project's cost was initially estimated to be $928 million,but the cost was revised downwards to $651 million. The World Bank had agreed to provide a $840 million loan for the project in June 2013. The loan had two components: The first component is a $400 million International Development Association loan,which will be lent as aconcessional loan at low interest rates.The second portion consists of a $440 million from the World Bank's International Bank for Reconstruction and Development. Pakistan's Water and Power Development Authority was to provide the remaining $74 million required for construction, before the project's cost was downwardly revised by $277 million. Interest costs for the loans are estimated to cost $83.5 million.
Because of revised lower costs to $651 million from $928 million, the World Bank permitted Pakistani officials to expedite completion of the project by 8 months at a cost of an additional $51 million. Pakistani officials were also permitted to divert $126 million towards the Tarbela-V Extension Project.
Tarbela-V extension project
The Tarbela Dam was built with five original tunnels, with the first three dedicated to hydropower generation, and the remaining two slated for irrigation use; the fourth phase extension project utilizes the first of the two irrigation tunnels, while the 5th phase extension will use the second irrigation tunnel. Pakistan's Water and Power Development Authority sought expressions of interest for the Tarbela-V Extension Project in August 2014, and was given final consent for construction in September 2015.
Construction is yet to begin, but will require an estimated 3.5 years for completion. The project will require installation of three turbines with a capacity of 470 MW each in Tarbela's fifth tunnel which was previously dedicated to agricultural use. Upon completion, the total power generating capacity of Tarbela Dam will be increased to 6,298 MW.
The hydro power project of tunnel no. 5 has two major components: power generation facilities and power evacuation facilities. The major works included under the project are: modifications to tunnel no. 5 and building a new power house and its ancillaries to generate about 1,800GWh of power annually, a new 50 km of 500kV double-circuit transmission line from Tarbela to the Islamabad West Grid Station for power evacuation, and a new 500kV Islamabad West Grid Station.
In November 2015, the World Bank affirmed that it would finance at least $326 million of the project's estimated $796 million cost which includes $126 million of funding that was diverted from the $840 million fourth phase extension project after costs for that project were revised downwards.On September 2016, the World Bank approved an additional financing of $390 million for the fifth extension hydropower project of Tarbela dam that will support the scaling up of the power generation capacity by adding 1,410 megawatts to the existing tunnel no. 5 of the dam. The project will be financed by the International Bank for Reconstruction and Development (IBRD), with a variable spread and 20-year maturity, including a six-year grace period. This will be the first World Bank-supported project in South Asia to be jointly financed with the Asian Infrastructure Investment Bank (AIIB) which will be providing $300m and the Government of Pakistan $133.5m. The total cost of the project is $823.5m.

What is the reason for the sudden stop of the submersible pump during operation
1. Power outage
Solution: Check the cause of the power outage and troubleshoot it.
2. The control protection switch trips (damage or overload occurs during the operation of the submersible pump)
- Measure the insulation resistance of the submersible pump motor, check whether the stator winding of the submersible pump motor is damaged,
and whether other components are damaged.
-Adjust the power supply voltage and operating conditions of the submersible pump to the allowable range to prevent overload during operation
and prevent tripping of the control and maintenance switch.
3. The core wire of the power supply cable is broken
Solution: - Connect the broken core wire of the motor power cable and wrap it with insulating tape.
-Take waterproof measures, as it is necessary to enter the water, so waterproofing and sealing are important.
4. The submersible pump impeller is stuck
Solution: Disassemble and inspect the water pump, remove debris, and ensure that the submersible pump can operate normally.
5. Damaged rotating parts such as bearings
Solution: Repair or replace.
6. The stator winding of the submersible pump is burnt out
Solution: Disassemble and repair the motor stator winding, and replace the damaged stator winding as required.

The Lake James to Fontenelle Park Project is one of several projects intented to remove and/or control flows in the combined sewer system and reduce the frequency, magnitued and duration of combined sewer overflows.
This project will expand the size and storage capacity of the existing Fontenelle Park Pond. It will also separate portions of upstream drainage basins to direct additional stormwater for detention in the improved Fontenelle Park Pond. By providing additional storage capacity, stormwater flow rates and volumes will be reduced in the downstream combined sewer system. By partnering with City Parks for this project, the pond will be expanded to a greater depth, water quality will be improved, and it is anticipated that fish may be stocked by Nebraska Game and Parks.
The construction of the Fontenelle Park Pond improvements began Feb. 2017 so the majority of the pond can be drained and excavated prior to the rainy season. Additional sewer construction and structures to control trash and grit for improved water quality within the park will also be accomplished with this construction.
The second phase, Lake James to Fontenelle Sewer Separation construction, will begin in spring/summer of 2018 to the south, west and north of Fontenelle Park. This sewer separation construction will transport stormwater to the new and improved Fontenelle Park Pond.

Perform hydraulic experiments specifically designed to validate the performance of numerical models used to predict the movement of a flood wave resulting from a dam break.
Numerical models are an important tool used in many areas of engineering and science that allow for rapid, inexpensive simulation of a variety of conditions. Accurate numerical modeling requires calibration by laboratory or field data. This helps to ensure that the model adequately captures the physics of the physical system and gives a standard to use in model testing and development. The need for calibration is especially relevant for hydraulic models, where bulk flow and turbulent quantities interact with structures such as streambeds, stream banks, dams, etc., in very complex ways. A new hydraulic model testing facility is to be constructed and housed at the National Sedimentation Laboratory. The facility will be designed and built for measuring transient flow during dam break scenarios. The design will also allow for convenient reconfiguration to meet future needs for model calibration and validation. High speed cameras and acoustic sensors will be used to record water surface profile data that will be compared to model results. The three general configurations which the facility will be designed for are as follows: 1. Simple dam break—non channelized flow. The downstream area will be wide with respect to the breach and can be equipped with or without sidewalls. Both dry and wet downstream conditions will be possible. Allowances will be made to add obstacles to the flow such as positive cutlines that are high or overtoppable and negative cutlines (dips, cuts). 2. Simple dam break—channelized flow. Configurable with/without bends with a free overfall at the end of test section. Wet or dry downstream with obstacles such as positive cutlines that are high or overtoppable and negative cutlines. 3. 1D-2D coupling with channel in line with dam breach and with/without irregular sidewall heights.


Earthworks and piping scope of works for the Roy Hill Central Transfer Pods project included:
- Bulk civil earthworks for construction of 3 large storage ponds.
- Bulk earthworks of 3.2kms of channel and 2.3kms of levee construction for the Zulu West hydraulic structure.
- Installation of 100,000 m2 HDPE liner.
- Ancillary mechanical and electrical works to facilitate water transfer to the ponds.

Dynamic Performance of Flow Control Valve Using Different Models of System Identification
This study measures the dynamic characteristics of flow control valve by a self-developed square pressure wave generator (SPWG). Comprised of a revolving shaft and a fixed ring, SPWG generates square pressure waves by the differential function of rotation between these two critical components. With the highly sensitive piezoelectric pressure sensor as the reference sensor, tests are conducted concurrently using a flow control valve. Under the same experimental parameters, the dynamic characteristics of flow control valve are evaluated by four kinds of system identification methods, namely ARX (Auto-Regressive with eXogenous input model), ARMAX (Auto-Regressive moving Average with eXogenous input model), OE (Output Error model) and BJ (Box-Jenkins model). The experimental results indicate that the dynamic performance of the tested flow control valve for resonance frequency, resonance peak and damping ratio are 1565.6 Hz, 0.9753 db and 0.4044, respectively.

(ST. JOSEPH, Mo.) Early Tuesday morning, the Missouri River in St. Joseph fell below major flood stage for the first time since last Wednesday. The river had been in major flood stage since March 20.
As of 7:30 a.m. Tuesday, the river was at 26.8 feet. Major flood stage begins at 27 feet.
Friday evening, the Missouri River set an all-time record crest of 32.11 feet.
The river gauges in Brownsville and Rulo, Nebraska and Atchison, Kansas are also below major flood stage.
The forecast as of Tuesday morning calls for the river to continue to fall, but heavy rain is in the forecast for the end of the week and that could lead to some rising of the river into the weekend.


While the state is getting some relief from recent heavy rainfalls that caused flooding across southern and western Wisconsin, high river levels continue to threaten several communities. The Baraboo River continues to be at major flood stage at Rock Springs and Baraboo in Sauk County. The Kickapoo River has crested, but remains at moderate flood stage at Viola, Steuben, and Gays Mills. There is also moderate flooding along the Rock River at Jefferson and the North Fox River at Berlin. No significant precipitation is expected until at least the middle of next week, which should help flooded areas dry out.

Data from monitoring equipment show the dam and power plant of the massive Three Gorges Project were undamaged by Tuesday's massive explosion that demolished the nearby cofferdam.
The 580-meter-long and 140-meter-high cofferdam protecting the just-completed main wall of the Three Gorges Dam was demolished Tuesday afternoon by a 13-second blast of 191 tons of explosives, enough to topple 400 10-storey buildings
"Although the waves caused by explosion were a little stronger than predicted, the dam and the power plant were unharmed," said Wu Xinxia, head of the demolition under the Yangtze River Academy of Sciences.
The power plant now operating in the dam's northern section remained undamaged by the explosion, said Ma Zhenbo, head of the Three Gorges Power Plant.
Prior to the explosion special devises were used to scare fish away and this move also proved successful as no dead fish were found, said Cao Guangjing, deputy general manager of the China Yangtze River Three Gorges Development Corporation.
The construction of the mammoth Three Gorges project started in 1994, and its major structure, the 185-meter-high main dam, was completed on May 20.
Following the dismantling of the cofferdam the Three Gorges Dam is now playing its role in flood control on the Yangtze River.

What the advantages about Stainless steel wafer type single disc lift check valve?
The lift check valve refers to a valve which is automatically opened and closed by the flow of the medium, and is used for preventing the backflow of the medium, also known as a check valve, a one-way valve, a counter-current valve and a back pressure valve.
Lift check valve is an automatic valve, its main function is to prevent media backflow, prevent pump and drive motor reversal, as well as container medium discharge.
When the medium flows into the valve body as shown by the body arrow, the pressure of the medium acts on the disc to produce upward thrust, and when the medium thrust is greater than the disc gravity, the valve opens.
When the force of the rear medium pressure on the disc and the gravity of the disc itself is greater than the force of the pre-valve pressure on the disc, the valve closes to prevent the media from flowing back.
H41H, H41 wafer type single disc lift check valve stainless steel non return valve has the advantages of simple structure, reliable operation and convenient maintenance.

PJSC RusHydro has begun construction of two small hydropower plants — Krasnogorskaya-1 and Krasnogorskaya-2 — on the Kuban River in Karachay-Cherkessia Republic.
According to a press release issued in June, RusHydro plans to build two hydropower stations, each with installed capacity of 24.9 MW and annual output of 83.8 GWh, downstream from its 160-MW Zelenchukskaya hydro and pumped storage power plant. The new facilities are to be commissioned in 2021 to 2022.
The new facilities will improve the hydrological regime of the Kuban River, lifting limitations on the capacity of Zelenchukskaya, which is currently set at 70 MW, RusHydro says. The regime optimization will add 230 GWh to the output of the Kuban Cascade annually.
The project will create 700 new jobs for the construction period.
Mosoblhydroproject, RusHydro’s engineering subsidiary, designed the plants.
“Development of renewable generation such as small hydro has always been an important part of business for RusHydro,” said Nikolay Shulginov, chairman of the management board — general director of RusHydro. “Within the year, we plan to commence construction of three small HPPs in the North Caucasus region and today we lay the foundation for construction of two Krasnogorskaya-1 and 2 small HPPs. Despite their small-scale these plants will have a significant positive impact on the power system of the Karachay-Cherkessia Republic.”
RusHydro is actively developing hydropower generation in Karachay-Cherkessia. In 2016, the company commissioned two hydropower units of the Zelenchukskaya HPP-PSP with capacity of 140 MW/156 MW (generation mode /pumping mode) and in 2018 commissioned a small HPP on the Zelenchuk River with capacity of 1.2 MW. Construction of the 5.6-MW Ust-Dzhegutinskaya HPP is in progress.

Manasan Ice Control Structure Rehabilitation & Bypass Designsby Fred E. Parkinson, LaSalle Hydraulic Lab, LaSalle, Canada,
Philip D. Wang, LaSalle Hydraulic Lab, LaSalle, Canada,
Document Type: Proceeding Paper
Part of: Waterpower '91: A New View of Hydro Resources
Abstract: Ice control works built on the Burntwood River at Manasan Falls were damaged during the 1985 spring break-up. The ice boom had broken and the lowered pond level indicated that the rockfill groins and/or the bottom paving had also been modified. Field surveys defined the damage underwater zones, and a physical scale model reproduced the flow conditions. Procedures were developed on the model to rehabilitate the works. The next phase of development on the Burntwood River required excavation of a bypass channel for flood flows greater than the capacity of the gap between the groins. The same physical model was used to refine the proposed bypass design. After repairs to the ice boom, the rehabilitation was completed in 1986 and the bypass channel was constructed in 1988/89. The new control works have operated as forecast over the winter seasons since their completion.
