Abstract: Locks and Dam 26 Replacement is proposed for construction on the Mississippi River about 2 miles downstream of the existing locks and dam at Alton, Illinois, as part of the program for the modernization of navigation facilities on the river. The project would replace the smaller existing structure with a large, modern structure designed to handle two-way traffic. The proposed structure would include two parallel locks separated by two 110-ft gate bays along the left bank and a dam consisting of a gated spillway and fixed overflow section. A fixed-bed model reproduced about 6.7 miles of the Mississippi River Channel, Ellis and Maple Islands, and the adjacent overbank areas to an undistorted scale of 1:120. The model study was concerned with the composition and configuration of the dam, arrangement and separation of the locks and lock walls, and navigation conditions in the lock approaches. The investigation has produced the following general results and conclusions: (A.) Satisfactory navigation conditions for two-way traffic could be developed at either the existing site or the proposed replacement site by providing gates between the locks. The number of gates in the proposed gated spillway could be reduced to seven without producing any significant changes affecting the movement of a tow approaching the locks. (B.) Currents in the upper approach to the landward lock at the alternate site would be affected by the eddy forming along the left overbank. Placing a fill along the overbank to an elevation above normal pool would reduce the effect of the eddy on navigation. (C.) Ports will be required in the upper guard walls to reduce the intensity of the crosscurrent near the end of the walls. The riverward lock guard wall should extend farther upstream than the landward guard wall. (D.) In the lower lock approaches, navigation conditions for two-way traffic could be improved with guard walls shorter than 1200 ft. (E.) With the locks separated, navigation conditions could be developed in both the upstream and downstream approaches with the locks used simultaneously without the operation of one interfering with the operation of the other. (F.) During construction of the project, adequate navigation conditions could be maintained by using a three- stage cofferdam with the first stage located on the Missouri side and the third stage along the Illinois side. (G.) Scouring of the bed can be expected along the upper corners of the cofferdams on the river side, particularly during long periods of extreme flow conditions. Along the main cofferdam, scouring can be eliminated or minimized with a deflector installed at the upstream corner on the river side of each cofferdam. NOTE: This file is large.

BHUBANESWAR: At a time when monsoon has been playing truant and August saw a rainfall deficit of 59 pc than normal, water level in major reservoirs including Hirakud has dipped significantly causing concern for hydro power generation.
Hirakud dam’s live storage level on Thursday, September 2, 2021, was 62.9 per cent (pc) of the total storage capacity. The current water level is 620.15 ft which is 9.85 ft down the full reservoir level of 630 ft. The water level on this day last year was 625.31 ft.
Water level in Hirakud fell as dam authorities opened 10 sluice gates in July expecting release of more water by Chhattisgarh due to heavy rains in the neighbouring state. The average inflow of water into the reservoir is 26,615 cusecs and the same quantity of water is being released for irrigation, industries and power generation purposes.
The water level is at an alarming level at Upper Kolab with 18.6 pc live storage. The reservoir level is at 847.9 mt against the full reservoir level (FRL) of 858 mt. The water level during this day last year was 850.54 mt.
The live storage filling of Machkund is only 24.4 pc, Balimela 25.3 pc and Indravati 30.2 pc of the FRL of 2750 ft, 1516 ft and 642 mt respectively. The current water level in these reservoirs is 34.9 ft, 48.3 ft and 10.52 mt lower than the FRL.
Though the water level in Rengali dam is about 80 pc of the full reservoir capacity of 123.5 mt, the current level is 2.5 mt less than the reservoir position on this day last year. The average generation of power from the seven hydro power plants including Chiplima is in the range of 700 MW to 860 MW. In a normal monsoon, the average hydro power generation of the State was around 1500 MW, informed sources in the State Load Despatch Centre.
The State has the advantage of sourcing cheapest power from its hydro stations and an average drop of 300-400 MW of power a day is a huge loss to the Odisha Hydro Power Corporation (OHPC) and the consumers of the State are deprived of cheaper power, said president of Odisha Bidyut Upabhokta Sangh Ramesh Satpathy.
If there is rainfall in the coming days, the situation is likely to worsen further and the State will have a difficult time to meet the power requirement during summer months when the demand for power is more, said sources in the Energy department.

BUKIT MERTAJAM: The Mengkuang Dam expansion project costing RM1.2 billion will be reinstated under the Ninth Malaysia Plan.
Energy, Green Technology and Water Minister Datuk Peter Chin Fah Kui said the project would begin before the end of the year, once the tender and documentation processes were finalised.
"The capacity of the dam upon completion will be increased from the current 23 million cubic metres to 78 million cubic metres, to meet the increasing water demand in the state," he said after visiting the dam yesterday.
The project, which will begin in October, is expected to be completed by 2013 and the water capacity will meet the state's demands …


A licence to enlarge Tzaneen Dam, a dam with a safety risk, was issued on Friday, 10 February 2023, to enable the construction work to begin on site.The project is aimed at augmenting the water supply in the Greater Letaba River Catchment of the Limpopo Province, by raising the dam wall by 3 meters, to increase the yield of the dam to address water shortages. This will then result in an increase in the gross storage capacity from 157 million to 195 million. This project is set to largely benefit the agricultural sector, as it will make water available for the establishment of resource-poor farmers in the irrigated agriculture sector around the area.
The Tzaneen Dam spillway was partially demolished in 2016 to allow the new spillway configuration in the form of a labyrinth type to be constructed. The scope of the work includes the demolition of the top of the existing spillway, the construction of a labyrinth spillway, and other minor works.The Development Bank of Southern Africa (DBSA) has been appointed as the Implementing Agent. The project target date to commence construction is March 2023, with an estimated project completion date of March 2025. To date, demolition of the original spillway has been completed, and this accounts for 10% project’s progress. Upon construction completion, Tzaneen Dam will be a 53,3 m high Category III dam. A Category III dam classification is the highest hazard rating by the Dam Safety Office, considering the size and the potential for loss of life in the unlikely event of a catastrophic failure of the dam.


In this study we introduce pump design work in which two vertical diffuser pumps are designed by using computational fluid dynamics and vane shape optimization. The first pump is a submergible pump having the specific speed of 300(m3/min-m-rpm). The effects of vane shape change on pump performance have been studied for this pump. Some effects of impeller inlet profile and diffuser blade angle are shown. Since this pump has very high head, the impeller exit angle of the first design model has been increased to get the specified head. This modification induces flow separation on the impeller blade. Blade angle distribution has been modified to eliminate the flow separation so that pump efficiency is maintained as high as in the base model. The second pump is a CWP for power plants having specific speed of 330. Blade shape is designed by using fractional factorial design method. The main effects and the interactions of design parameters are investigated. Impeller inlet diameter is increased to get better NPSH required performance. Flow analysis shows that the design model has higher efficiency and better cavitation performance than the existing model.

JACKSONVILLE, Fla. – The U.S. Army Corps of Engineers Jacksonville District has awarded the final construction contract for the Kissimmee River Restoration Project, a massive Everglades restoration project in Okeechobee and Highlands counties.
The $17,887,000 S-69 Weir and Canal Backfill construction contract was awarded to Herve Cody Contractor from Robbinsville, North Carolina on September 26.The contract involves backfilling nearly one-half mile of the C-38 canal, from the historic river channel crossing to the S-69 weir, which is being constructed as part of this contract. The weir will be located downstream of the backfilled C-38 canal and will slow the flow of water transitioning from the restored Kissimmee River floodplain to the remnant C-38 channel.
Access to portions of the Kissimmee River will be closed to navigation for the duration of the construction contract. Backfilling operation are scheduled to begin in the fall and will take approximately 20 months to complete. During this time, navigation in the C-38 Canal will be prohibited between S-65A and S-65D, north of the US Hwy 98 Bridge. Navigation south of the construction site will be available via the S-65D Boat Ramp.
“Construction of the S-69 Weir will maximize wetland rehydration in the Kissimmee River Basin by providing connectivity between the historic Kissimmee River floodplain and backfilled portions of the C-38 Canal,” said Tiphanie Mattis U.S. Army Corps of Engineers Jacksonville District project manager. “We are working to put the final components in place for this project in order to provide significant benefits to the Kissimmee River Basin, Lake Okeechobee, and subsequently, the entire Everglades ecosystem.”
To date, the Corps has completed over 30 construction contracts as part of the Kissimmee River Restoration project. With the award of the S-69 Weir and Canal Backfill contract, only one construction contract remains for the project.
The Kissimmee River Restoration project is a congressionally authorized undertaking by the U. S. Army Corps of Engineers and the South Florida Water Management District, the non-federal sponsor. The project encompasses the removal of two water control structures, filling approximately 22 miles of canal, and restoring over 40 square miles of the river channel and floodplain ecosystem, including approximately 27,000 acres of wetlands.
In restored areas, comprehensive monitoring has documented substantial improvements in the river and its floodplain, making the project a model for large-scale ecosystem restoration efforts. Aquatic wading bird and duck populations in the restored river and floodplain region have soared, shorebird species have returned, organic deposits on the river bottom have decreased by 71 percent, and reestablished sand bars provide new habitat for native species. In addition to the significant ecological improvements provided by this project, restoration of the historic river will also slow the movement of water and increase the time it takes for it to get to Lake Okeechobee, helping to slow down the rise in the lake

Clark Canyon Hydro LLC on Nov. 20 filed a final license application with the Federal Energy Regulatory Commission for a hydroelectric project to be added at the existing Clark Canyon Dam in Montana.
The Flood Control Acts of 1944 and 1946 approved the construction of the Clark Canyon Dam as part of the Bureau of Reclamation’s (BOR) Pick‐Sloan Missouri River Basin Program, East Bench Unit. The approximate 2,950 foot (ft) zoned, earth‐fill dam includes a concrete intake structure and conduit in the reservoir, shaft house at the crest of the dam, a 9‐ft‐diameter conduit that discharges water to a concrete stilling basin, a gate chamber with four high pressure gates, two of which act as emergency gates, and an uncontrolled concrete spillway.
Located near the town of Dillon in Beaverhead County, Montana, the Clark Canyon Dam is situated on the Beaverhead River. Uses for the water at the dam for authorized project purposes include irrigation, flood control, fish and wildlife, and municipal water. No proposed new dams or reservoirs are included in the Clark Canyon Dam Hydroelectric Project.
The dimensions of the powerhouse to be built will be approximately 46 feet by 65 feet. The powerhouse will contain two vertical Francis-type turbine/generator units with a combined generating capacity of 4.7 MW, and a combined discharge capacity of 700 cubic feet per second (cfs).
The powerhouse substation will be located northeast of the powerhouse (approximately 1,100 ft downstream of the powerhouse). The substation includes a 4.16 kV to 69 kV step-up transformer with switchgear on concrete pad foundations with containment and a grounding grid. An underground transmission line will be between the powerhouse and the powerhouse substation.
The new transmission line will run from the powerhouse substation approximately 7.9 miles to the Peterson Flat substation and will be adjacent to and within sections of the Highway 324 right-of-way (ROW).
At the selected size, the project will use flows ranging from 87.5 cfs to 700 cfs (87.5 cfs to 350 cfs per unit), and will have a maximum static head of 110 feet and an average static head of 87 feet. On average, the project will generate approximately 15.4 gigawatthours (GWh) per year. The project will function in a “run-of-river” mode with no daily storage for power generation, and no peaking operation.

Numerical modelling of Flow characteristics over sharp crested triangular and W-shaped weirs for establishing downstream scour behavior
Weirs are flow control devices that are often used in waterways. As the weirs by nature change the flow patterns in the water ways, significant changes in the flow structure in the vicinity of the weir structure can be easily seen. These significant changes in the flow patterns create significant changes in the surrounding flow geometries. Scour in the downstream of the weir is fairly well-known side effect in the channels. The objective of this study is to evaluate the flow characteristics of a triangular sharp crested weir and its comparison with W-shaped sharp crested weir using CFD (Computational Fluid Dynamics) with Ansys Fluent as the main tool. Important flow characteristics, before and after two weir shapes have been evaluated and their potential to cause scour in the downstream evaluated with a view establish relationship between weir shape and the likely scour area has been investigated. It has been found that weir shape has significant influence on scour behaviour and this study may be used a reference for future evaluation of scour potential of weirs of different shapes.

In centrifugal pumps, the interaction between the rotating impeller blades and the stationary diffuser vanes generates specific pressure fluctuation patterns. At off design operation, high incidence and large local pressure gradients can lead to flow separations in rotating or stationary components of centrifugal pumps. The resulting rise of mechanical vibration levels may negatively affect the operational performance and the life span of mechanical components. This paper presents detailed pressure fluctuation measurements performed in a high speed centrifugal diffuser pump stage at full scale in the stationary and in the rotating domain at various locations for different operating conditions. The analysis of pressure fluctuations experienced at the impeller blade trailing edge clearly allowed the detection and exploration of flow separations in the channels of the vanned diffuser. The observed flow separation in the diffuser channels can be stationary or rotating with different rotational speeds and number of stalled channels, depending on the relative flow rate of the pump. The non-uniform pressure distribution at the impeller periphery, which is depending on the flow separation within the diffuser channels, changes the impeller deformation pattern and creates high local stresses in the junction between the impeller blades and the impeller shrouds. The detection of rotation or stationary stall by using either shaft vibration measurements or bearing force measurements has been demonstrated to be a useful mean of avoiding unfavourable pump operation.

New pump station transmission mains have been installed onsite and offsite in Irving St. near the Creekstone roundabout. Onsite excavation and removal of spoils for the reservoir has been completed. New reservoir inlet & outlet pipeline across the Creekstone Park has been installed and connected. The reservoir structure is approximately 95% complete and most of the future pump station piping has been installed.
Major Construction Activities Coming Up
Restoration of the Creekstone Park is underway with an anticipated reopening to residents for use during the first part of September. The contractor is working on completing the remainder of the reservoir structure. Completion of the new reservoir is scheduled for September 2021. Immediately following completion of the reservoir the contractor will begin construction of the pump station. Completion of the new pumping station is scheduled for Spring of 2022. De-construction of the existing concrete reservoir will occur near the end of this project in early 2022.


BRONXVILLE, N.Y. – Construction related to improvements of storm-water drainage systems, is expected to begin in January 2015 with a completion date of August to early September 2015.
The project -- part of the Federal Emergency Management Agence flood mitigation grant project awarded to Bronxville in 2012 -- will benefit the Bronxville School campus, and will also aid neighbors on Meadow, Willow and Midland Avenue, and even in Bolton Gardens.
Based on a cost-benefit analysis, factoring in the storm events of 2007 and 2011 in which the school alone had losses upwards of $28 million, FEMA determined the project to be cost effective at a dollar value of nearly $6.9 million. The village entered into a funding agreement with FEMA where FEMA would cover 75 percent of the cost with the village and school district evenly splitting the remaining 25 percent.
The following upgrades are part of the project:
- A new flow diversion structure will be installed in the alignment of each of the two existing primary water conveyance trunk lines to divert excess runoff
- A new storm-water pump station will be constructed in the parking lot on the school campus to deliver the excess runoff diverted from the existing trunk lines to the Bronx River
- Five diesel-powered pumping units will be installed with a pumping capacity of 100,000 gallons per minute
- A below-grade concrete wet well will be built to receive the pump suction lines and to provide temporary runoff storage during pumping
- Construction of an architectural wall enclosure around the pumping units for aesthetics and noise attenuation
- A new below-grade storage piping network will be constructed below the existing natural turf field (Hayes Field) on the school campus.
- A new conveyance system pipe will be installed from the pump station location to Scout Field directing the excess runoff to the Bronx River via Laurel Brook. The new force main will cross Midland Avenue extending across library and village hall property to the area near the intersection of Palumbo Place and Gramatan Avenue. A new stabilized drainage channel will also be constructed on Scout Field to direct excess runoff from the force main pipe.
Specifically, the pump station will capture and deliver excess storm-water runoff to the Bronx River before flooding occurs under most storm event conditions because it will utilize a dedicated force main pipe so that storm water can reach the Bronx River.

This paper presents a Flood Prediction Model (FPM) to predict flood in rivers using Artificial Neural Network (ANN)
approach. This model predicts river water level from rainfall and present river water level data. Though numbers of factors are
responsible for changes in water level, only two of them are considered. Flood prediction problem is a non-linear problem and to solve
this nonlinear problem, ANN approach is used. Multi Linear Perceptron (MLP) based ANN’s Feed Forward (FF) and Back
Propagation (BP) algorithm is used to predict flood. Statistical analysis shows that data fit well in the model. We present our
simulation results for the predicted water level compared to the actual water level. Results show that our model successfully predicts
the flood water level 24 hours ahead of time.

Pressurized GRP Pipeline
Elmalı HEPP is a diversion type hydropower project located in the Eastern Anatolia Region within the border of Erzurum province over the Serçeme Creek. Elmalı HEPP makes use of the head between 1988 m and 1905 m.
The project is located downstream of Kuzgun Dam & HEPP with a seasonal storage capacity. The long free flow conveyance channel in the original design was replaced by a pressurized GRP pipeline near riverbed in order to reduce construction costs, expropriation and to shorten construction duration. Although the optimum design discharge of Elmalı HEPP (16.5 m³/s) was determined to be less than design discharge of Kuzgun HEPP (23 m³/s), the excess water released by Kuzgun HEPP during peak hours was effectively stored in the Elmalı Weir reservoir thus resulting in an economically more feasible project.

Predicting Water Levels at Kainji Dam Using Artificial Neural Networks
AbstractPoor electricity generation in Nigeria is a very serious problem. Accurate prediction of water levels in dams is very important in power planning. Effective power planning helps in ensuring steady supply of electric power to consumers. The aim of this study is to develop artificial neural network models for predicting water levels at Kainji Dam, which supplies water to Nigeria's largest hydropower generation station. It involves taking of a ten-year record of the daily water levels at the dam from 2001 to 2010. The daily water level data were used to develop five neural network models and an Autoregressive Integrated Moving Average (ARIMA) model to fit the daily water levels obtained in the year 2010. The results show that the prediction accuracy of the neural network models increased with increasing input, but after the four-input model the accuracy started declining. The four-input neural network model had the lowest relative error of 0.062 percent while the single-input model had the highest relative error of 0.237 percent. The ARIMA model with relative error of 0.039 percent had the best prediction. Generally, the models' predictions were good, but the neural network models which involve little mathematics were much simpler to build. The developed models will be very useful in power planning in Nigeria's hydropower stations for more ecient power supply.

Wandfluh has extended the proven pressure reducing valve with an execution for use in very corrosive environments. It is made of stainless materials and coated with high-quality surface protection and can control volumes up to 80 l/min with up to 350 bar.
The pilot operated 3-way valve reduces the input pressure to an adjustable output pressure. The pressure reducing valve regulates the output pressure largely independently of the input pressure. A rise of the outlet pressure above the set value, e.g. by an active consumer, is prevented by a pressure relief function which diverts the excess pressure to the third connection. With the pressure ranges 63, 160 and 350 bar, it can be adapted to the respective application requirements.
The adjustment of the desired pressure can take place by means of a tool or by various control knobs. With the option “cover”, the adjustment can be protected against unauthorized access. The valve is available with the designation MV_PM22_K9. It is mainly used in areas with continually changing weather conditions or in the vicinity of the sea.


- Dniester Pumped Storage Power Station
Dniester Pumped Storage Power Station Country Ukraine Location Sokyriany Coordinates Coordinates: Status Partially operational Construction began 1983 Commission date 2009-2017 Owner(s) Ukrhydroenergo Reservoir information Upper reservoir Dniester Upper Reservoir capacity 38,800,000 m3 (31,456 acre·ft) Lower reservoir Dniester HPP-I Dam Reservoir capacity 70,000,000 m3 (56,750 acre·ft) Pumped-storage station information Generating units 7 x 324 MW reversible Francis turbines Hydraulic head 38.7 m (127 ft) Power generation information Installed capacity 324 MW Maximum capacity 2,268 MW
The Dniester Pumped Storage Power Station is a pumped storage hydroelectric scheme that uses the Dniester River 8 km (5 mi) northeast of Sokyriany in Chernivtsi Oblast, Ukraine. Currently, one of the seven 324 MW generators is operational and when complete, the power station will have an installed capacity of 2,268 MW.
As part of the Dniester Hydro Power Complex, the pumped storage power station (PSP) was planned in the 1970s along with two dams (Dniester I & II) and a nuclear power plant. In 1983, Dniester II, a dam which creates the PSP's lower reservoir, was completed. The PSP was approved by 1988 and construction began that same year. Three years later in 1991 though, construction was suspended due to a funding fallout from the dissolution of the Soviet Union. The project was re-approved in 1993 and construction commenced again in 2001. Project costs increased due to the poor state of the existing facilities which were not maintained while the project was suspended. On December 22, 2009, the PSP's first generator was commissioned. The second and third generators of the first stage are expected to be operational in 2011 and 2012, respectively. Ukraine's problems funding the project have been compounded by controversy surrounding the project's transparency and impacts on the environment and water flow to Moldova downstream. Ukraine had sought funding from the World Bank who, in 2007, only funded US$29.6 million towards the PSP's electrical transmission system. Industry experts believe Ukraine will be able to complete the project independently. The power station is expected to be fully operational in 2017.
Design and operation
The power station begins operation by using reversible turbines to pump water, during low energy demand periods, from the lower reservoir which is created by the Dniester HPP-II Dam, located 7.5 km (5 mi) to the southeast near the border with Moldova at liver"-shaped embankment dam. The upper reservoir has a 38,800,000 m3 (31,456 acre·ft) storage capacity. During periods of high energy demand, water is released from the upper reservoir back to the power station for generation. This process is routinely repeated and helps balance loads. The difference in the two reservoirs affords a hydraulic head of 38.7 m (127 ft).. The lower reservoir has a storage capacity of 70,000,000 m3 (56,750 acre·ft). Water pumped from this reservoir is placed in the upper reservoir which is formed by a 360° "
While only one is currently operational, the power station will contain seven 324 MW reversible Francis turbine generators. Its installed capacity will be 2,268 MW when generating and during pumping, the power station will consume a maximum of 2,947 MW. Regulating flows into the lower reservoir is the Dniester HPP-I Dam which is located upstream, 9 km (6 mi) north of the power plant at . HPP-I has its own power plant with an installed capacity of 702 MW and a storage capacity of 3,000,000,000 m3 (2,432,140 acre·ft). HPP-II has an installed capacity of 40.8 MW.

Flood Safety Projects along the Tisza river in Hungary
Flood Safety Projects along the
Tisza river in Hungary
Between 1998 and 2001, four extraordinary floods occurred in the Tisza River Basin. Considering the magnitude of the endangered areas, the populations threatened, and the goods damaged, these floods broke every record in the upper and middle Tisza areas. Evaluation of the repeat floods made it clear that the method of heightening and strengthening dams to protect the country against floods should be reconsidered.
The ‘Improvement of the Vasarhelyi Plan’ (IVP) project has been developed, aiming to provide flood safety by storing excess water in reservoirs. The overall objective of the programme is to increase the discharge capacity of the flood bed together with the ecological revitalisation of the floodplain.
Preparatory studies have looked at ways to facilitate an increase in the discharge capacity of the flood bed through alteration of land use, and have identified around 30 sites which might be able to store excess water as reservoirs. Between 10 and 12 sites have been selected which have the total storage capacity of around 1,500 million cubic metres. According to preliminary calculations, this capacity is enough to decrease the peak levels of extreme floods by one metre all along the Hungarian section of the Tisza.
Prompted by the results of these extensive preparatory studies, the Hungarian government adopted a decision on the first stage of the IVP in 2003. During this first stage of the plan, six reservoirs (Cigand-Tiszakarád, Szamos-Kraszna-közi, Nagykunsági, Hanyi-Tiszsülyi, Tiszaroffi reservoirs and part of the Nagykunsági reservoir) will be built. In addition, the discharge capacity of the flood bed will be improved.
The IVP also aims to establish new landscape management in the territory of the reservoirs as well as regional, rural, and infrastructure development – which will result in a healthier Tisza River Basin.

The Fengman hydropower station originally built in 1937 on the Songhua River in Jilin Province is one of the oldest hydroelectric facilities of China. It has been reconstructed with a total installed capacity of 1.48GW to eliminate safety hazards and provide better flood control.
The £1.04bn ($1.33bn) reconstruction project was executed by State Grid Xinyuan Company, a subsidiary of State Grid Corporation of China (SGCC), in collaboration with Jilin Provincial Government and the Songliao Committee of the Ministry of Water Resources.
The project involved the construction of six new power generating units of 200MW capacity each and retention of last two old units (unit 11 and 12) of 140MW capacity each.
The first three new units were put into operation between September and December 2019. The units four and five were commissioned in April and July 2020, respectively, followed by the commissioning of the sixth unit in September 2020.
The reconstructed Fengman hydropower station plant has an annual electricity generation capacity of 1.709TWh.
New Fengman dam and reservoir details
The Fengman hydropower station reconstruction project involved the construction of a new roller-compacted concrete (RCC) gravity dam, approximately 120m away from the original dam. The sideline of the new dam’s foundation pit is just 40m away from the old dam.
The 1,068m-long and 94.5m-high dam has a storage capacity of 10 billion cubic metres (bcm).
The reservoir is fed from a constant flow of the Songhua River, which originates from Heaven Lake at the top of Changbai Mountain situated at an elevation of 2,189m above the sea level.
New Fengman hydropower plant make-up
The new Fengman hydropower station comprises six sets of 200MW Francis turbine generator units.
The other equipment installed at the power station includes computer monitoring systems, relay protection systems, excitation systems, speed control systems, condition monitoring systems and power station auxiliary systems.
The new power plant also houses a 550kV ELK-3 gas-insulated switchgear (GIS) along with HVR-63 and HECS-80M generator circuit-breakers (GCBs) equipped with GMS600 monitoring system.
Contractors involved with the Fengman hydropower station reconstruction
Chinese Academy of Water Sciences, East China Survey and Design Institute, Beijing Survey and Design Institute, and Northeast Survey Design Institute were engaged in the feasibility study for the reconstruction project.
Harbin Electric Machinery was appointed as the mechanical and electrical contractor in December 2015. The contract scope included the construction, installation and the commissioning of six hydro turbine generator sets.
ABB supplied the GIS and GCBs for the Fengman hydropower station reconstruction project under a contract awarded in August 2016.
Original Fengman hydropower station details
The Fengman hydropower project was originally conceived by the Japanese Kwantung Army Command that had invaded Manchuria (now Northeast China). The dam was built by the Japanese between 1937 and 1942, while start of power generation started in 1943.
The hydropower station was taken over by the Northeast People’s Government of China in 1948.
The hydropower station was developed in three phases with a total installed capacity of 1,002.5MW.
Eight generating units of total capacity 552MW were put into production by 1960 under phase one, while units nine and ten of 85MW capacity each were brought online by June 1992 as in phase two.
In phase three, two more units (units 11 and 12) of 140MW capacity each were commissioned in July 1998.
The original concrete dam was 1,080m-long and 91m-high with a reservoir storage volume of 8.85bcm. The power plant catchment area was 42,500km2.
Also known as the “cradle of China’s hydropower” and “mother of China’s hydropower”, the Fengman dam project is considered to have significantly contributed to power generation, flood control and ecological environment protection.
Fengman hydropower station reconstruction background
With congenital defects and potential safety hazards, the old Fengman hydropower station was recognised as a disease dam by the State Electricity Regulatory Commission Dam Safety Supervision Centre in 2005.
The State Grid Corporation of China (SGCC) made a request to the National Development and Reform Commission (NDRC) for the preliminary work of reinforcement at the Fengman hydropower station in February 2006.
The reconstruction project was approved by NDRC in October 2012, while the demolition of the old dam was commenced in October 2018.

WALL JET FLOW SIMULATION IN A RESERVOIR USING A THREE-DIMENSIONAL MATHEMATICAL MODEL
Fatih ÜNEŞ, Mustafa DEMİRCİ, Hakan VARÇİN
ABSTRACT. – Density and divergence flow analysis in a dam reservoir is essential from the point of view of reservoir sedimentation studies, water quality modeling, habitat in reservoirs, effluent mixing analyses, and circulation flows in ambient waters of a dam. In the present study, different density inflow was modeled in three-dimensions along a dam reservoir with diverging and sloping bottom channels. Nonlinear and unsteady continuity, momentum, energy and turbulence model equations were formulated in the Cartesian coordinates. k-ε turbulence model including density effects was used to the turbulence viscosity. The Coriolis force effect was also included in the governing equations for a dam reservoir. The generated model was solved based on the initial and boundary conditions of the dam reservoir flow for a range of bottom slopes and divergence angles. The model successfully simulates the formation of wall jets in ambient water. The present model simulation results were compared with previous experimental work. The present model results were compatible with the experimental results.

India and Pakistan agreed on redesigning the Miyar Hydroelectric project, at the end of two-day talks of Indus Water Commissioners in Islamabad.
It was also agreed that the Lower Kalnai and the Pakal Dul projects would be inspected again.
The talks between the two countries began after 22 months when Pakistan in 2015 skipped consultations following objections on the Kishenganga and the Ratle hydroelectric projects by India.
Kishenganga is in arbitration while officials of the two countries are meeting in Washington next month on the Ratle project on the invitation of the World Bank.
Pakistan’s request for arbitration on Ratle is still pending with the World Bank, which is the guarantor of the 1960 Indus Water Treaty.
About Kishenganga Project
The Kishanganga Hydroelectric Plant is an $864 million dam which is part of a run-of-the-river hydroelectric scheme that is designed to divert water from the Kishanganga River to a power plant in the Jhelum River basin. It is located 5 km north of Bandipore in Jammu and Kashmir, India and will have an installed capacity of 330 MW. Construction on the project began in 2007 and is expected to be complete in 2016.
About Ratle Project
The Ratle Hydroelectric Plant is a run-of-the-river hydroelectric power station currently under construction on the Chenab River, downstream of the village of Ratle in Doda district of the Indian state of Jammu and Kashmir. The project includes a 133 m tall gravity dam and two power stations adjacent to one another. Water from the dam will be diverted through four intake tunnels about 400 m southwest to the power stations. The installed capacity of both power stations will be 850 MW. On 25 June 2013, Prime Minister Manmohan Singh laid the foundation stone for the dam. The project is expected to be complete in February 2018. Pakistan opposes to project as they believe it is in violation of the Indus Water Treaty.


Integration of Probabilistic and Physically-Based Modelling with Optimization Methods for Stormwater Infrastructure Rehabilitation.
Probabilistic stormwater flows are determined using kinematic wave routing methods and long-term historical rainfall. A multiobjective chance constrained optimization model, subject to constraints based upon physical modelling and historical rainfall data, is applied to a stormwater drainage network in Atlanta, Georgia. The optimization model objectives include minimization of total rehabilitation costs and maximization of stormwater system reliability. Rehabilitation alternatives include replacement, upgrading and varying the design capacity of the drainage system. This modelling approach can be used to develop trade-off relationships between the minimum rehabilitation cost and the probability of failure of the drainage system due to stormwater events. Results of optimization with a simplified runoff model (the rational formula with intensity-frequency-duration curves derived from Gumbel statistical methods) are compared to the results obtained by kinematic routing of stormwater through the channels and pipes of the network, using long-term historical rainfall as input.
