The concrete river channels before you are part of the Pittsburgh District, U.S. Army Corps of Engineer's [sic], Johnstown Local Flood Protection Project (JLFPP). It is the longest paved channelization project in Pennsylvania and one of the largest in the United States. Congress authorized construction of the project through amendments to the landmark federal Flood Control Act of 1936. The project is a specialized engineering structure eligible for listing on the National Register of Historic Places.
The JLFPP was constructed between 1938 and 1943 to handle river flows equivalent to those experienced in Johnstown during the 1936 St. Patrick's Day flood. Flood protection improvements consisted of deepening and widening the channels in the Conemaugh, Little Conemaugh, and Stonycreek rivers and the construction of concrete side slopes and floodwalls.
The project has been a success. In its six decades, the project was overtopped only once during the exceptional "500-year flood" of 1977. Through 2002, the project has provided over $803 million in flood damage prevention benefits.

SACRAMENTO, Calif. - The U.S. Army Corps of Engineers Sacramento District is performing drilling operations along the northbound lane of Highway 155 in Lake Isabella, California, as part of the Isabella Lake Dam Safety Modification Project.
Traffic control measures are in place for traffic to travel through the construction zone along the southbound lane, but the roadway will remain open to traffic in both directions. Drilling will occur during daylight hours, and is expected to be complete by Nov. 6.
Geologic data from three borings will help provide pertinent information for design of a floodwall to be constructed adjacent to the roadway as part of the Corps’ project, which will raise both the main and auxiliary dams and their abutments on each end up to 16 feet.
The Isabella Lake dam safety project is currently in the design phase, and the team is continuing to research and refine designs to allow for minimal disruption and impact when the project begins construction in 2017.
Completed in 1953, Isabella Lake Dam is located approximately 42 miles northeast of Bakersfield. The reservoir is impounded by two earthen dams on the Kern River and Hot Springs Valley. Today, Isabella Lake and its dams reduce flood risk for Bakersfield and the surrounding region, and is a primary water source for water users throughout Kern County. The Isabella Lake Dam Safety Modification Project will address overtopping, seismic and seepage issues identified with Isabella Lake’s Main and Auxiliary dams to reduce the likelihood of dam failure. In 2013, the Corps entered the pre-construction engineering and design phase of the project.

The Turga pumped storage project (TPSP) is a 1,000MW pumped storage hydroelectric project proposed to be developed in the Purulia district of West Bengal, India.
West Bengal State Electricity Distribution Company (WBSEDCL) is the implementing agency of the project. It will also own and operate the facility, upon completion.
The £764m ($920m) project is being developed with Japanese financial assistance that covers more than 70% of the total project cost.Pre-construction activities on the project were started in October 2016, while land acquisition was completed in February 2017, followed by the grant of forest clearance in July 2018.
Scheduled for commissioning in 2028, the Turga pumped storage facility will be used to supply peak power and to contribute to the grid stability in the region.
Turga project background
The Turga pumped storage project is being developed near the 900MW Purulia pumped storage plant (PPSP) located in Bagmundi, which has been operational since 2008. Turga was identified as one of the four potential pumped storage development sites in the area, in a survey conducted by the Central Electricity Authority (CEA), Government of India, in 1979.
The CEA approved the detailed project report (DPR) for the Turga pumped storage project in October 2016, while the project received the cabinet approval from the Government of West Bengal in May 2017.
Turga pumped storage power plant make-up
Turga is designed as a closed-loop type pumped storage project involving an upper and a lower dam with a total catchment area of 12.66km² and an underground powerhouse downstream of the upper dam.
The upper dam will be a 732m-long rock-fill dam across the Turga Nala, a tributary of Subarnarekha River. The catchment area of the upper dam will be 8.29km².
The lower dam will be an 872m-long concrete dam with a catchment area of 4.37km². It will be developed by augmenting the existing Turga Dam. Both the upper and lower dams will be up to 64m-high.
Water from the upper reservoir to the powerhouse will flow through two 618m-long headrace tunnels, and two 224m-long and 9m-diameter steel-lined penstocks. The powerhouse will release water to the lower reservoir through two tailrace tunnels, which are 7m and 10m in diameter.
The underground bullet-shaped powerhouse will be 160m-long, 25m-wide, and 55m-high. It will be equipped with four 250MW Francis vertical shaft reversible pump-turbine units, including two variable speed and two fixed speed pump-turbine units.
The Turga Pumped Storage Project envisages utilisation of rainfall in the catchment of the Turga Nala. The surplus water will be pumped to the upper reservoir, where it will be stored for power generation when demand peaks.
The facility will be capable of geerating 1,000MW of electricity for a period of five hours during periods of peak demand.
The electricity from the pumped storage facility will be evacuated to the national grid through a 1.7km-long double-circuit 400kV transmission line, which will connect the existing PPSP substation.
The Turga pumped storage project is planned to be developed with a Japanese Official Development Assistance (ODA) loan of £552m ($665m) .
The Japan International Cooperation Agency (JICA) and the Government of India signed a loan agreement for £202m ($243m) for the project in November 2018.
Location and site details
Encompassing 292ha at an elevation of 600m, the Turga project site is located on the Ayodhya Hills near Baghmundi village in the Purulia district of West Bengal, India.
Road access to the project site is via the Balarampur-Baghmundi state highway. Air access is via Ranchi airport, which is located approximately 160km from the project, while railways extend up to the nearby town of Balarampur.
Haldia and Kolkata are the nearest ports from the project site.
Water and Power Consultancy Services (WAPCOS), a state-run consultancy organisation of the Government of India, provides consultancy services for the project.
J-POWER conducted the preliminary studies and prepared the final technical reports for the Turga pumped storage project.

Barkley Dam was authorized for construction in the River and Harbor Act of 1954 for the purpose of navigation, flood control and hydropower. Construction began in June 1957 and completed for full beneficial use in July 1966. Today, Lake Barkley is also managed for recreation as well as fish and wildlife. It is the lowermost mainstream project on the Cumberland River System impounding 118.1 miles of the Cumberland River from River Mile 30.6 above its confluence with the Ohio River to Cheatham Dam (River Mile 148.7).
The project was first identified as the Lower Cumberland Project, but was later redesignated as Barkley Lock and Dam and Lake Barkley in honor of the late Alben W. Barkley, the 35th Vice President and United States Senator from Paducah, Kentucky.


Innovative TSHD fitted out with Damen semi-axial dredge pumps
The state-of-the-art 3,200 m3 Trailing Suction Hopper Dredger (TSHD) Charlock has been equipped with two Damen dredge pumps. One highly innovative semi-axial dredge pump is fitted on the trailing pipe, the other dredge pump is mounted inboard. Both dredge pumps work in series, enabling a highly efficient dredging process.
The semi-axial dredge pump is a new addition to the wide Damen dredge pump range. As for all Damen dredge pumps, it has been designed for the harsh dredging environment with special focus on minimising wear and maximising efficiency. The semi-axial dredge pump installed on the Charlock, type OBP9080HA, has various advantages for the owner. Its weight is relatively limited, reducing the required hoisting capacities of the gantries and winches on board. Moreover, the limited cross section minimises the drag forces in the drag arm. Also, the required power is limited; the semi-axial pump is equipped with a 1,200 kW electric motor. Nonetheless, the semi-axial dredge pump delivers some 16,000 m3/h of mixture at 50% concentration and at an excellent efficiency of 85%.
The cast dredge pump wear parts have been designed in close cooperation with the foundry. All cast elements, including the 2-parted pump casing, have been dimensioned optimising the foundry process boosting the casting accuracy and reducing the risk on mis-casts. Hence, the quality of the cast parts is improved. The various wear parts can be cast in different materials depending on the material to be dredged.
The semi-axial dredge pump will work in series with the Damen inboard dredge pump, type BP8065MD. The low pressure semi-axial dredge pump delivers the dredged mixture with minimal head at the inboard dredge pump. This single-walled centrifugal dredge pump either delivers the mixture to the hopper during loading, but it can also pump ashore using the bow coupling unit or rainbow. The inboard BP8065MD dredge pump is driven by a 3,200 kW electric motor.
Damen is pleased to have taken part in the design and delivery of a TSHD as innovative as the Charlock.


The Hypro 6500C-R roller pump is designed for agricultural and industrial spraying applications. Its durable cast iron construction stands up to the toughest jobs.

Construction for the first phase of this project is complete. The project included draining the lake, replacing stormwater drainage and sanitary sewers, and transforming the upper lake to a stream channel. The new stream channel flows through the newly constructed stormwater infrastructure into the lower lake. These changes will improve the channel's water quality and reduce flooding to nearby homes.
Since the dam structure at the lower lake is not functioning properly, the lake will be drained through the start of the second phase of this project. This will limit the amount of water in the lake, which will reduce impacts from heavy rain storms and ensure the ongoing safety of residents living near the lake.
If you have any questions about this project, contact Todd Rall, at 919-996-4006 or Todd.Rall@raleighnc.gov.
This project will provide dam and storm drainage improvements at the Brockton Drive dam by addressing dam safety concerns, reducing the frequency and severity of flooding in adjacent structures, and improving water quality, while remaining consistent with the City of Raleigh's Lake Preservation policy.
The Brockton Drive Lake and Dam Rehabilitation will be completed in two phases:
Phase I - Upper Dam: This phase includes removing the upper lake to restore the channel at Brockton Drive and increasing the size of the existing drainage pipe with a box culvert. Stream restriction at the downstream corner of Walden Woods Club House pool will be removed. The stream also will be stabilized and reshaped with plants/vegetation at the upper stream channel.
Phase II - Lower Dam: The spillway structure and the lower dam will be replaced with a roller-compacted concrete structure.
|Summer 2016||Bid proposal, Phase I design, easements acquisition, and private utility coordination complete|
|Fall 2016||Phase I bid and award complete|
|Summer 2017||Phase I construction begins|
|Winter 2018||Phase II design complete|
|Summer 2018||Phase I construction complete (Planting to possibly take place in Fall 2018)|
|Coming Soon!||Phase II construction begins|
The existing spillway for the upper lake at Brockton Drive is currently in very poor condition. The upper lake collects debris and, in intense storms, floods adjacent structures, which are occupied. The lower lake dam spillway is undersized and there is severe erosion at the outlet.


Due to the increase in land development and inadequate stormwater conveyance, the W-15 Drainage Basin in St. Tammany Parish, Louisiana experiences significant flooding. Beginning in 2011, DDG developed a comprehensive plan for drainage improvements. The project consisted of preparing a HEC-RAS and HEC-HMS for a project area of 35-square miles that encompasses three separate but interconnected basins including W-15 Canal, W-14 Canal, and Gum Bayou Basin. Utilizing previous model data from the Southeast Louisiana Urban Flood Control Project (SELA) as well as newly acquired topographic and bathymetric data, models were developed to understand existing flooding conditions and to evaluate various alternatives for improving flood conveyance and storage. A total of 27 different alternatives were evaluated to determine the most economical solution to alleviate the existing flooding problems in different parts of the basin. A Benefit Cost Analysis (BCA) was prepared for FEMA to facilitate the award of Hazard Mitigation Grant Program (HMGP) funds.
The recommended project included the construction of a 324-acre regional detention pond and cleaning and widening of approximately 3 miles of the W-15 Canal. This project accomplishes two objectives: reducing peak runoff to the W-15 Canal downstream of the Tenet Pond and increasing the conveyance capacity of the W-15 Canal. These two project elements effectively reduce the water surface elevations along the W-15 Canal thereby reducing impacts to structures throughout the W-15 Basin. DDG provided engineering services to St. Tammany Parish that included engineering design, permitting, preparation of bid documents and construction inspection.

The quantification of the changes in channel geometry and sand load that have occurred on the Missouri River after engineering works and that characterize the Altamaha River in the fluvial-tidal transition zone is the main objective of this research. Dam construction and channelization on the Missouri River resulted in flow regulation, sediment shortage by dam reservoir trapping, channel straightening and narrowing. Quantifying the morphodynamic response of the Lower Missouri River to these engineering projects at short and long-time scales is a difficult problem that we approach with the analysis of the available field data and with the aid of a one-dimensional morphodynamic model. The results show that the peak discharge and suspended sand load have reduced remarkably downstream of Gavins Point Dam, i.e. the lowermost dam on the Missouri River mainstem, and have recovered gradually to pre-dam levels downstream of the junctions with major tributaries. The analysis of mean daily flows reveals no observable change in high flow magnitude and frequency downstream of the Missouri River – Grand River confluence. Model results show no significant change in mean annual sand load in the downstream-most part of the study reach for short and long-term simulations. Recent studies on river morphology in the fluvial tidal transition zone show significant changes in channel geometry and sediment size over relatively short distances with the cross-sectional area and the sediment size decreasing the oceanward direction. The collection and analysis of field data in the fluvial- tidal transition zone of the Altamaha River presented herein provides greater insight into the characteristics and causes of these spatial changes. Stream power and Shields number were used to explain the observed changes, which occur over a distance ranging from 1 to 4 km. The analysis showed a sharp decline in stream power and Shields number at the boundary between the fluvial and tidal dominated reaches. This decline is thought to be responsible for the observed changes in channel geometry and sediment size.

To achieve this goal, the capacity of hydropower projects planned to begin construction in the 12th Five-Year Plan 2011-15 will be expanded by 50 GW, according to a draft proposal recently submitted to the National Development and Reform Commission by China Electricity Council.
According to the draft proposal, the capacity of new conventional hydropower projects planned to begin construction in the 12th Five-Year Plan has been upgraded from 63 GW to 83 GW, and the capacity of new pump-storage hydropower projects planned to kick off construction has been upgraded from 50 GW to 80 GW.
At of the end of 2009, the installed capacity of conventional hydropower in China was 182.25 GW, including 55.12 GW of small hydropower. The installed capacity of pump-storage power stations was 14.54 GW.
The construction period for hydropower projects usually lasts five years or more. This means most of the projects planned for completion by 2020 will kick off in the next five years.
However, there are still many difficulties to achieve this goal. In the past five years, many large hydropower projects failed to kick off construction as scheduled for environmental reasons. At of the end of 2009, there were only 11 key hydropower stations that had received approval, accounting for only 27.1 of the total key hydropower projects listed in the 11th Five-Year Plan 2006-10 for renewable energy development. The different pricing system adopted for hydropower is another issue to be solved. The current price level of hydropower is much less than the average level of thermal power due to insufficient consideration in environment and resettlement.
The situation has obviously changed. The Chinese government has recently approved a large number of key hydropower projects, including major dams planned on the upstream portion of the Yangtze River and its tributaries. Hydropower development in China is speeding up.

Keywords: Intake flow; Surface vortex; HSMAC method; Large Eddy Simulation
Abstract: Three-dimensional unsteady flow with localized areas with large vortices in the intake channel of a small-scale model hydroelectric power station has been simulated numerically using a Large-Eddy Simulation (LES) technique. The method computes the fluctuating position of the free surface using a modified HSMAC iteration method. The standard Smagorinsky model with wall damping is used for the sub-grid scale model. With the total number of grid points of about one-third of a million (cid: 231) in the rectangular mesh, the near-wall flow is marginally resolved for the laboratory-scale Reynolds number, and complex and unsteady nature of the vortical flow can be reproduced reasonably well. Flow characteristics in the intake channel are known to be strongly influenced by the flow properties in the inflow plane, and the present calculation method is found to be able to reproduce the trends with respect to these inflow conditions. Surface vortex of weak intensity can be captured and the flow conditions associated with appearance of vortices can be examined based on the results of the present simulation.


The project consists of the construction of an underground system proposed to be built beneath Hillcrest Drive beginning at Apache Creek just north of Woodlawn and continuing down to 36th St. beneath Globe Ave., terminating at Apache Creek on St. Mary’s University. This system will augment the existing underground system beneath Belfair Drive that will remain in place. The proposed system will be capable of passing the ultimate 1% chance (100-Year) storm. The system passes runoff to Apache creek which eventually ties to Zarzamora Creek.

Description for Gibe V Multi-Purpose Project (Ethiopia)
The Gibe V (660 MW) multipurpose project is the fifth and last stage of the Gibe-Omo hydroelectric cascade, following Gilgel Gibe, Gibe II, Gibe III (all operating) and Koysha (under construction).
It is the final step in the development of the entire hydropower potential of the Omo river and represents a realization of the large-scale vision started more than 25 years ago with the design of the Gilgel Gibe hydroelectric power plant.
Moreover, its multi-purpose reservoir allows also the use of regulated waters for the irrigation of a large area identified by the Environmental Study favouring the development of the local community.
The project is located approximatively 70 km downstream of Koysha and with its 660 MW of installed power will be able to produce approximately 2’000 Gwh/y.
The dam is an RCC gravity type with a maximum height of about 63 m, a crest length of about 580 m and an overall volume of approximately 400’000 m3.
A large spillway is incorporated in the central part of the dam body constituted of an overflow crest divided into ten bays and controlled by radial gates. The smooth chute ends in a stilling basin, foreseen for energy dissipation.
Cofferdams, culverts and low blocks are envisaged for river diversion on the left side of the river. During river diversion, the water flow will be controlled by the u/s reservoirs (Gibe III and Koysha). As a consequence of this control, the peak flow is substantially reduced and will be diverted by large culverts and over a “low block”.
The power penstocks are incorporated into the dam body and the powerhouse is located at the dam toe. Due to the presence of the wide energy dissipator, the outdoor powerhouse is divided into two sections of six turbines each. Access from one section to the other is guaranteed by a gallery under the energy dissipator, into the downstream toe of the dam body.
Due to the particular situation, a small gantry crane is envisaged in each section while a large outdoor gantry crane will serve both sections of the powerhouse. Between the two sections, the crane will run over rails on a bridge over the energy dissipator.
- RCC Gravity Dam (H = 63 m, L_crest = 580 m)
- Spillway on dam body (N° 10 gates, W x H 12x19 m)
- River Diversion Works (No. 2 culverts, D = 12 m, L = 240 m)
- Dam body Power House (No. 12 Francis turbines, IP = 12x55 MW)
- Switchyard (350 x 150 m, 400 kV line bays)

A boundary-fitted coordinates method was successfully employed in the evaluation of the discharge coefficients, as well as the free-surface profiles, for vertical and radial sluice gates for an ideal fluid. The values of the discharge coefficients and the free upstream and downstream surface profiles are in good agreement with the literature. Some details of the flow, such as the velocity profiles and the bed pressure deficit upstream of the gate, can also be predicted accurately. The boundary-fitted coordinates method was demonstrated to be a viable method in the study of fluid flow with initially unknown discharge and unknown free-surface profiles.

In the construction of anti-filtration curtains, the injection hardening of rocks is applied (mainly by cementation), which is most widely used in the hydraulic engineering construction, in which Hidroinjekt LTD is closely specialized. It is used in the construction of anti-filtration curtains on dam walls, the main purpose of which is to seal the rock base and reduce its water permeability. It is also used to increase the strength of the rock and reduce its deformability. For this purpose, a large volume of injection work is performed.


The Upper Karnali hydropower project is a run-of-the-river hydropower project being developed on Karnali River in Nepal.
The project will supply power to Nepal, India, and Bangladesh for a contracted period of 25 years.
The Government of Nepal awarded the project to GMR Upper Karnali Hydro Power Limited (GUKHL), a subsidiary of GMR Group India, under a memorandum of understanding (MoU) signed in January 2008. GMR is developing the project on a build-own-operate-transfer (BOOT) basis.
The Nepal Government received 27% free equity in the project, as part of the MoU with GMR.
Project development agreement (PDA) of the hydro project was signed between the Government of Nepal and GMR Group in September 2014.
The project saw a halt in development for a few years because of delays in securing financing due to lingering market uncertainty for the electricity generated by the project. The project is expected to be commissioned during the 2023-2024 financial year.
With an estimated investment of approximately $1.5bn (£1.23bn), the plant is expected to create more than 3,000 jobs during construction. It is estimated to generate 3,466 million units of electricity, while offsetting approximately two million tons of greenhouse gas emissions a year.
Upper Karnali hydropower project location and make-up
The Karnali hydropower project site is located on the Karnali River within three districts namely Surkhet, Achham, and Dailekh. It will feature a concrete gravity dam, headrace tunnels, a fish pass, feeder tunnels, surge and pressure shafts, and silt flushing tunnels.
The reservoir will have a surface area at FRL of 1.96 million m², with a power density of 459.18W/m².
The main spillway will be gated Orifice type with five bays, each measuring 11m-wide and 14m-tall.
The diversion tunnel/sediment diversion tunnel will be a 1,050m-long, 9m-wide horseshoe shaped tunnel. The concrete gravity dam will be 207m-long and 64m-high above the foundation.
From the diversion tunnel, water will be conveyed to the power house through two horseshoe-shaped headrace tunnels (HRT) measuring 10m in diameter. The HRTs will measure 2.2km and 2.3km, respectively.
The surge shafts will consist of two units measuring 42m-high and having an internal diameter of 25m.
The pressure shafts will consist of four units, measuring 6m in diameter and between 250m and 275m in length. Each shaft unit diverges into two 50m-long limbs with a diameter of 4.25m each.
The surface power house will be located on the right bank of Karnali River and will feature eight vertical shaft Francis turbines, each with a capacity of 112.5MW. The turbines will operate at a rated net head of 150.11m and rated speed of 214.3rpm.
Power transmission and off-take
The power generated by the Upper Karnali hydropower project will be transmitted to the North East West Northern Eastern (NEWNE) India grid through a 400kV double-circuit transmission line.
The 400kV export power is expected to be transmitted to the pooling station at Bareilly in Uttar Pradesh, owned by Power Grid Corporation of India (PGCIL).
Nepal is entitled to receive 12% free power from the total power generated by the project, while 56% will be sold to Bangladesh under a long-term power purchase agreement (PPA). The remaining 32% will be sold to India under short-term/mid-term/long-term bilateral purchase agreements.
The project is proposed to be funded by Asian Development Bank (ABD), Asian Infrastructure Investment Bank (AIIB), JICA, CDC, and Nepal Investment Bank (NIBL).
GMR Group also signed a partnership agreement with International Finance Corporation (IFC), in December 2014, for assisting the project in achieving financial closure.
