INDONESIA'S HYDROPOWER STORAGE 1 GW
ENERDATA - 14 Sep 2021 - The World Bank has awarded a US$380m loan to build the 1,040 MW Upper Cisokan pumped-storage hydropower plant, to be located between Jakarta and Bandung in Indonesia. The power plant, currently under construction, is expected to be commissioned in 2025. The project's significant power generation capacity will enable to meet peak demand. In addition, it will provide a large storage capacity, increasing the penetration of renewable energies in the power mix; currently, over 80% of the power generated for the Java-Bali grid that supplies electricity to 70% of the country’s population comes from fossil fuels. Finally, the Upper Cisokan hydropower project will alleviate increasing transmission loads on the grid thanks to its close location to two large demand centers.

Energy DEWA expects hydroelectric plant completion in Q4 2024 By Pramod Kumar December 27, 2022 WAM Dewa was listed as a public company on the Dubai Financial Market in April 2022 The pumped-storage hydroelectric power plant that Dubai Electricity and Water Authority (DEWA) is building in Hatta is 58.48 percent complete, state-run WAM news agency reported. This is the first station of its kind in the GCC, with investments of up to AED 1.421 billion ($387 million). The project is planned for completion in Q4 of 2024. The power plant will have a production capacity of 250 megawatts (MW), a storage capacity of 1,500 megawatt-hours and a life span of up to 80 years. Saeed Mohammed Al Tayer, managing director and chief executive of DEWA, inspected the construction site at the hydroelectric power plant, including the power generators’ site and upper dam, where the water intake in the Hatta Dam connected to the power generators has been completed. Construction of the 72-metre main roller compacted concrete wall of the upper dam has been completed. Al Tayer also inspected the work progress of the water tunnel, which is 1.2 kilometres long and connects the two dams. The concrete lining of the water tunnel is complete. He said the power plant is part of DEWA’s efforts to achieve the Dubai clean energy strategy 2050 and the Dubai net zero carbon emissions strategy 2050 to provide 100 percent of Dubai’s total power production capacity from clean energy sources by 2050. The hydroelectric power plant will be an energy storage facility with a turnaround efficiency of 78.9 percent that utilises the water stored in the upper dam, which is converted to kinetic energy during the flow of water through the 1.2-kilometre subterranean tunnel.

Wave transmission prediction of multilayer floating breakwater using neural network
MetadataShow full item record
In the present study, an artificial neural network method has been applied for wave transmission prediction of multilayer floating breakwater. Two neural network models are constructed based on the parameters which influence the wave transmission of floating breakwater. Training and testing of the network models are carried out for different hidden nodes and epochs. The results of network models are compared with the measured values. It is observed that the correlation (above 90%) between predicted wave transmission values by the network models and measured values are in good agreement.

The existing Riverview Lift Station was constructed in the 1960s and has the capacity to pump 3.5 million gallons per day (MGD) to the Missouri River Water Resource Recovery Facility (MRWWRF). A new lift station was needed to ensure flows from the Riverview and Grover Street sewers can be reliably pumped into the new South Interceptor Force Main and to maximize conveyance of wet weather flows to the MRWRRF. Lift station capacity is also needed to accommodate the Henry Doorly Zoo cleaning and draining of exhibits and facilities.
The new lift station was designed to have the capacity to pump 7.0 MGD and to help reduce CSO discharges. The location of the Riverview Lift Station Replacement Project is just west of the existing lift station, adjacent to Gibson Road. Work includes construction of two diversion structures at the existing Grover and Riverview Street combined sewers to capture flows and convey them to the new Riverview Lift Station.
Substantial completion to be reached when pump testing is complete.
The Blake Street Lift Station Improvements Project was added as a contract change order.

Nyadi project building power line
Lamjung, December 30
Nyadi Hydropower Project, a 30MW power project based on the Ngadikhola in Lamjung’s Marsyangdi Rural Municipality, has started construction of a transmission line required for feeding power generated from the project to the national power grid.
On account of the delay in construction of the proposed 220KV national power grid on the Marsyangdi Corridor, the project has begun work towards construction of a 9km 132KV transmission line from the project site to Lampata. “We are scheduled to start power generation from March/April next year but apparently as the transmission line won’t be ready by then, we have been compelled to construct the transmission line ourselves,” said the project’s Chief Executive Officer Uttam Amatya.
Of the 25 towers to be built for the transmission line, work on nine towers is under way as of now. “If everything goes as planned, the work will accelerate once we finish acquiring land and providing compensation for the same,” said the project’s public relations officer Bijaya Gurung. “For the transmission line, there will be 15 towers in the 6km stretch from the project site to Tunikharka and another 10 towers in the 3km stretch from Tunikharka to Lampata,” Gurung said, adding that the transmission line would link the power generated from the project to the transmission line developed by the Upper Marshyangdi A Hydropower Project.
The estimated cost of the project, expected to produce 168 GW of power annually, is six billion rupees.

River channel flood forecasting method of coupling wavelet neural network with autoregressive model
Li Zhijia Zhou Yi Ma Zhenkun(College of Hydrology and Water Resources,Hohai University,Nanjing 210098,China)
Based on analyzing the limitations of the commonly used back-propagation neural network (BPNN), a wavelet neural network (WNN) is adopted as the nonlinear river channel flood forecasting method replacing the BPNN. The WNN has the characteristics of fast convergence and improved capability of nonlinear approximation. For the purpose of adapting the time-varying characteristics of flood routing,the WNN is coupled with an AR real-time correction model.The AR model is utilized to calculate the forecast error.The coefficients of the AR real-time correction model are dynamically updated by an adaptive fading factor recursive least square(RLS)method.The application of the flood forecasting method in the cross section of Xijiang River at Gaoyao shows its effectiveness.

Little Para Reservoir is a reservoir in South Australia serving the city of Adelaide. It was built between 1974 and 1977, costing A$11.5 million, and commissioned in January 1979.
The reservoir is built in the path of the Little Para River and is used for water storage and flood mitigation. As the Little Para’s catchment is insufficient to fill the reservoir, it is mainly used to store water pumped from the River Murray. Periodically water is released from the reservoir into the river, enabling refreshing of ground water. source Wikipedia (http://en.wikipedia.org/wiki/Little_Para_Reservoir)

Governor, Inlet Valve, unit side panel, excitation system
The Francis type turbine is mostly suitable for hydropower stations with medium or high head from 10m to 300m. They are in both vertical or horizontal shaft arrangement and could be vastly selected by the hydraulic power stations.
lts feature is that the water flow enters the runner inward in a radial direction , changes direction gradually and then passes out axially. Francis turbine is characterized by reliable operation, simple construction and high efficiency, etc. Hydoru manufacture Francis runner have a good efficiency and cavitation performance.
Normally, we adopt the horizontal Francis with capacity below 5MW, runner diameter below 90cm. And the vertical Francis with capacity below 20MW.
Main Structure of Francis Hydro Turbine
This hydraulic turbine type is Horizontal shaft Francis. A inlet valve is equipped in front of the spiral casing of the turbine. When viewed at the turbine from the generator end, the rotating direction of the hydraulic turbine is clockwise .The turbine is horizontal shaft and metallic spiral casing and the stainless steel runner. This unit has two bearings, assembled on the generator seat. The principal parts of the structure of turbine as follows:
3) Rotating parts
5) Draft tube
6) Layout for water,instruments and pipe-line
Water flows through penstock of the power station, Butterfly valve, expansion pipe, inlet tube, spiral case and wicket gates into the runner, and then it drives the runner to revolve and convert hydraulic energy into mechanical energy and drives the rotor of generator revolution by the force of the main shaft of turbine, thus converting the mechanical energy into electric energy.
Francis turbines are the most common water turbine in use today.
They operate in a water head range of 10 to 300 meters and are primarily used for electrical power production. The power output generally ranges from 100KW to 750MW.
Normally, Medium size and larger Francis turbines are most often arranged with a vertical shaft, Small francis turbine always arranged with horizontal shaft, but it is not absolute.

Kidston's Pumped Storage Hydro Project will be the first hydropower facility to use an abandoned mine.
The 250MW fixed speed reversible Francis turbines will be Australia's first hydro storage project in more than 40 years. Once finished the facility will be Australia's third largest electricity storage facility.
Construction began in January 2022 and is being overseen by Genex Power a renewable energy, generation and storage company based in Australia. The project will form an integral part of Genex's Kidston Clean Energy Hub which will see solar, wind and hydroelectric generation being developed in addition to the storage hub.
The storage facility will have capacity to store 1,870 MWh of electricity each generation cycle.
The property is situated on the historic Kidston Gold Mine in North Queensland. The mine which operated for over 90 years was closed in 2001.
The pumped storage hydro project will use Wises pit, a shallow water body situated on the upper reservoir. Eldridge pit will be used as the lower reservoir as it is 320m deep and currently holds the majority of the 25 gigalitres of water located within the scheme. Wises pit will be broadened and reinforced in order to create a larger cavity dam using existing waste water rock dumps at the site. The dam will feature a high-density polyethylene liner as a cost-effective sealant.
The underground powerhouse of the project will be constructed within a 90m long cavern. It will be installed with two 125MW reversible pump Francis turbine units, two main inlet valves, two 275kV step-up transformers and two draft tube gates.
The hub will supply Australia's National Electricity Market through a new 275kV transmission line.

The use of coupled models of hydrologic analysis, which includes more than one component of the hydrologic cycle, is a common occurrence. Coupled models tend to be more complex and their solution may suffer numerical complications. In this study, we present a coupled hydrological model to simulate the interaction between stream flow and groundwater flow. A one-dimensional stream flow model using the complete form of the St Venant equation is coupled with a two-dimensional vertically averaged groundwater flow equation in an unconfined aquifer. The governing equations of the two different hydrological domains are linked with the recharge term at the river bed. The resulting coupled mathematical model is solved simultaneously by linking the two hydrologic system matrices in a global matrix. The proposed simultaneous solution approach provides a more efficient solution for the coupled flow problem and is superior to the approximate solution obtained through an iterative approach.


Water Technology was engaged by Baw Baw Shire Council to design and model a proposed combined Retarding Basin (RB) and Wetland (WL) located north of Stoddarts Road, Warragul. This proposed RB/WL forms part of Council’s overall Development Contributions Plan for the Shire. The project included the design of a retardation system consisting of two storages connected in series, three sediment ponds treating a proposed development and the greater catchments flows, one wetland as well as the realignment of an unnamed waterway. A hydrological RORB model was built for the Stoddarts Road catchment in order to design the size and characteristics of the retarding basin. MUSIC was used to size the stormwater WSUD treatment assets before preparing the design drawing for submission to Council. Figure 4 4 shows the Stoddarts Road Wetland detailed design drawing. An Initial ANCOLD assessment was undertaken for the retarding basin infrastructure as part of the design.

British Columbia Hydro and Power Authority (BC Hydro) is building the third hydro-electric power plant on the Peace River in northern British Columbia. The dam is being constructed nearby Fort St John.
To enable the actual dam construction a series of cut-off wall structures was required. In order to meet the specified construction schedule, cut-off wall works had to be executed through the winter months facing the harsh winter conditions of Northern Canada. Temperatures during wall installation were as low as - 25° Celsius. The main cut-off wall construction works were carried out in multiple shifts 24 hrs/day and 7 days/week during August 2016 and November 2017.
BFCA's scope of work comprised the installation of four cement bentonite cutoff walls at various locations along the new proposed dam. Up to three excavation units (both hydraulic and rope grabs) were mobilized for the project. 80,000m² cut-off wall were installed over a total length of approx. 3.7km. The wall had to be embedded into the weak sandstone/mudstone rock. In places up to 3.8 m rock embedment was achieved to reach the designed wall toe levels. The panel excavation reached a maximum installation depth of approx. 25m.


Reduction in the Storage Capacity of Dokan Dam Reservoir
- 128 Downloads
Dokan reservoir is located on the Lesser Zab River NE Iraq. Its drainage area is 11,690 km2 with a storage capacity of 6.87 × 109 m3. Calculation of the volume of the reservoir before the construction of the dam and from the bathymetric survey conducted in 2014 indicates that an annual average of 7 million cubic meters of sediments are deposited within the reservoir. This reduced the storage capacity of the reservoir by 28%.

Nam Ngiep 1 hydro plant starts impounding water
BORIKHAMXAY (Vientiane Times/ANN) - The Nam Ngiep 1 Hydropower Project (NNP1) began impounding water in its re-regulation reservoir on May 15 with electricity generation scheduled to start before the mandated date in early 2019.
This will be after all the electrical and mechanical installation is completed and the 115 kV transmission line is built by Electricite du Laos.
The hydropower project will have installed capacity of 290MW and is under construction in Borikhamxay and Xaysomboun provinces. The project consists of the construction of two dams and two powerhouses along the Ngiep River in Borikhamxay province. It is the smaller of the two dams which has now been completed.
According to project staff, impounding is expected to last for 10 days. During this period not less than the prescribed minimum riparian release will be allowed to flow downstream with the water level in the reservoir controlled to rise by about one metre per day unless a natural rain event upstream causes extreme flood conditions.
After completion of impounding the water will have reached the top of the labyrinth weir, 179 metres above sea level. After that water will continuously overflow from the re-regulating reservoir, with flows proportional to the natural inflow into the river.Some minimal disturbance to the flow and the water level of the Ngiep River downstream of the re-regulating dam is expected during this short period of impounding.
“The Nam Ngiep 1 Hydropower Project is one of the priority projects of the Lao government. It is expected to contribute to poverty alleviation once it starts to generate revenue for the government from the sale of electricity,” Governor of Borikhamxay province Dr Khongkeo Xaysongkham said at the impounding ceremony.
“I would like to congratulate and thank everyone who has worked tirelessly towards this milestone. This is another remarkable achievement and one step closer to completion of the construction of the project,” Managing Director of the Nam Ngiep 1 Power Company Limited, Mr Yoshihiro Yamabayashi, said.
Construction of the project started in late 2014 and, as of the end of April 2017, about 68 percent by value of work was completed, with all critical parts of the works on, or ahead of schedule. Progress is expected to be 90 percent by value by the end of 2017 and substantial early completion of construction of the project is planned by August 2018.
The project expects to begin generating electricity in late 2018 or early 2019. About 95 percent of this power will be exported to Thailand, the remainder being used for domestic consumption.
The project expects to generate more than US$600 million in direct revenue and other indirect benefits to the Lao government during its 27-year concession period, after which ownership will be transferred to the Lao government.

The City of West Linn contracted with Murray Smith & Associates for the design of a new 4.0 MG (million gallons) water reservoir to replace the existing 2.5 MG Bolton Reservoir, which was built in 1915. The design and construction of this project is being funded through a combination of SDC funds, Water Revenue, and funds received from Lake Oswego for the Lake Oswego-Tigard Water Partnershi
Inspection requests for Public Works Permits (e.g. NFP-16-05, FP-16-05) or for an inspection related to a development project (e.g. PI-16-05) must now be done through the Engineering Department's Inspection Request Webform.


The proposal is to redevelop the existing Victoria Reservoir on Munday Brook, approximately 20 kilometres east of Perth. This is considered necessary by the Water Authority of Western Australia due to the age and condition of the existing dam, and timely in view of the current residential and rural development pressures being placed on the associated water catchments.
Redevelopment of the Victoria Reservoir would involve the creation of a new larger dam to replace the existing structure to gain additional water yield. Associated with this is the development of a pumpback water supply on the existing Bickley Brook Dam, using additional capacity available in the new Victoria Reservoir to store the winter flows from the lower Bickley catchment. The land included within the Victoria catchment area proposed to be flooded by the creation of the new dam is gazetted for water catchment.

Buckshole reservoir safety works
The three reservoirs within Alexandra Park were built in Victorian times to supply water to Hastings. Buckshole Reservoir, the largest of the three and the last to be built is now more than 150 years old.
The reservoirs no longer supply drinking water, but they are still an asset to the town, providing a focus for fishing, recreation and wildlife.
Work on Buckshole Reservoir to bring it up to the Environment Agency's latest safety standards has now been completed. Landscaping work to restore the area around the reservoir will be completed in the spring when the weather and ground conditions improve.
The improvement works included:
- A new outlet pipe, to be built within the existing overflow structure, which will allow the reservoir to be drained in a timely manner should a problem with the dam ever be detected.
- A new spillway channel to replace the original and aged structure which has now deteriorated beyond economic repair. The new channel will be larger than the original to ensure it can cope with and protect the dam from the largest predicted floods.
The outflow from Buckshole Reservoir is controlled by multi-level weirs at the upstream end of the siphon overflow chamber, which was built as part of work in 1985.
The main objective of the 2022 work was to protect the embankment dam structure from damage and possible failure during extreme flood events. This has been achieved by increasing the capacity of the spillway channel downstream of the 1985 structure. However, he increased capacity of the channel does not mean more water will be passed downstream - this will continue to be controlled by the weirs that were built upstream in 1985.
The footpaths that were closed during the works have now been reopened.

Hydraulic design considerations for orifice spillways
- Gadge, Prajakta P., Jothiprakash, V., Bhosekar, V. V.
- ISH journal of hydraulic engineering 2019 v.25 no.1 pp. 12-18
- equations, guidelines, mathematical models, sediments, spillways
- Orifice spillways have been widely recognized as the most appropriate especially for run-of-the-river projects for handling both flood releases and flushing of sediments. The present paper discusses various important parameters to be considered in the design of an orifice spillway, evolution of orifice spillway, and structural design consideration. A need for physical and numerical model for modeling spillway flows has been identified. Literature review on physical and numerical model studies of orifice spillway has been reported. Central water and power research station has contributed in evolving the design of orifice spillway by conducting hydraulic model studies for more than 25 projects. However, no guidelines have been developed as the data was site-specific for each case. Based on the data, a need for further research is identified and discussed in detail. Roof profile is found to be an important hydraulic parameter as it affects the discharging capacity of the orifice spillway. However, design of roof profile has not been standardized so far. Hence, basic research studies were taken up to develop the design guidelines for roof profile using physical and numerical models. The important findings obtained from the basic research study have also been discussed in the present paper. An equation was developed to design the roof profile, which will be useful for the engineers at the initial stage of design of orifice spillway.


Non-slam check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent medium backflow, also known as a check valve, one-way valve, counterflow valve, and back pressure valve. Non slam check valve belongs to an automatic valve. Its main function is to prevent medium backflow, reverse pump and drive motor, and discharge of container medium.
The opening and closing parts open or close by themselves depending on the flow and force of the medium, so as to prevent the reverse flow of the medium, the valve is called non slam check valve. Non-slam check valve belongs to automatic valves. It is mainly used in pipelines with a one-way flow of the medium. It allows medium to flow in one direction only to prevent accidents.
Non-slam check valves can be divided into three types according to their structure: lifting non-slam check valves, swing non-slam check valves and butterfly non-slam check valves.
1. Lifting non-slam check valve is divided into vertical and horizontal.
2. Rotary non-slam check valve can be divided into three types: single-lobe, double-lobe, and multi-lobe.
3. Butterfly non-slam check valve is straight-through.
The above non-slam check valves can be divided into threaded connection, flange connection, welding connection, and clamp connection.
According to the structure, it can be divided into three types: lifting non-slam check valve, swing non-slam check valve, and butterfly non-slam check valve. The lifting non slam check valve can be divided into two types: vertical and direct. Rotary non-slam check valve can be divided into three types: single-lobe, double-lobe, and multi-lobe. The butterfly non-slam check valves are butterfly double-lobe, butterfly single-lobe and the above non-slam check valves can be divided into four types in connection form: threaded connection, flange connection, welding, and clamping connection.

Baitarani River Crosses Danger Mark In Bhadrak
Bhadrak: Due to heavy downpour in the catchment for the last couple of days under the influence of a low pressure over the Bay of Bengal, the Baitarani river has breached the danger mark near Akhuapada in Bhadrak district.
As per the latest report, the river was flowing at 17.85mts against the danger mark of 17.83mts on Thursday.
People residing in low-lying areas along the riverside are feared to be affected following a rise in the water level of the Baitarini river.
They are spending a sleepless night as the river has been flowing above the danger level thus anticipating floods at any time.
Meanwhile, the water level of the Subarnarekha and Jalaka rivers in Balasore district has been continuously rising to breaches in several places.
The Odisha Water Recourses Department on Thursday said that it is closely monitoring the situation and assured to take up restoration operations as soon as the water recedes.

New Veytaux power station (FMHL+)
Existing power station Veytaux
Situation plan of the new Veytaux power station
With the FMHL+ project the capacity of the Veytaux pumped storage power station will be increased from 240 MW to 480 MW, 60 MW act as a reserve. To achieve this, two machine groups with 120 MW capacity each will be installed in a new cavern that is currently being excavated. The construction work has been in progress since 7 April 2011. After its commissioning, which is scheduled for the autumn of 2016, the pumped storage power station with one billion kWh of peak energy per year will generate virtually twice as much electricity as at present (520 million kWh). In order to achieve this, Forces Motrices Hongrin-Léman SA (FMHL), in which Alpiq holds a share of almost 40 percent, is investing 331 million Swiss francs.
Significance of pumped storage and of FMHL for the security of supply
The pumped storage power station Veytaux will play a crucial role in supplying electricity to the French-speaking part of Switzerland. The project is the response to the increasing demand for balancing energy, which has been triggered by the rapid development of the new renewable energies that generate energy in an intermittent and fluctuating manner. Thanks to its high degree of flexibility, the Veytaux power station is able to quickly balance out such fluctuations. At peak times, the water from the Hongrin reservoir is channelled through the turbines of the Veytaux power station located 800 metres lower down, while during off-peak times, the excess energy is used to pump water from Lake Geneva up to the Hongrin reservoir.
