Strathcona Dam Water Discharge Upgrade Project
About The Project
- Construct a new low-level outlet structure to provide the capability for a deep reservoir drawdown, which is currently not possible. This work includes construction of a deep channel and placing two gates in a concrete structure located within the bedrock on the right or east side of the dam. Post-earthquake, having a lower reservoir level will reduce the risks to the dam, and the controlled water releases from the dam also manages the risks to the downstream dams.
- Replace the existing three spillway gates and related works such as the hoist system with a new concrete overflow spillway, improving the reliability of the spillway system. With the two new gates to be placed within the new channel, in addition to the Strathcona Generating Station discharges, they will provide for downstream water management for fish, power generation and flood risk management.

NORTH COUNTY – The Okanogan River, which has been at flood stage since late last week, began receding Wednesday morning after topping out at about 17.1 feet.
The river is considered to be at flood stage at anything above 15.0 feet and has been there since May 10. At 17, flooding is considered “moderate” but water levels remained above that for only a few hours.
Cooler weather, which is slowing the rate of mountain snow run-off, will help to bring water levels down over the next few days, though rain could change things.
Current NWS flood information can be found here.

The Scaldis Lock is a lock on the Lower Scheldt in Ghent. It was necessary to construct the lock because the water level of the Lower Scheldt and the other watercourses in Ghent city centre were approximately 1.2 m higher than the water in the Lys at Nieuwbrug quay and Portus Ganda. The Scaldis Lock was delivered with a slide-off for kayaks.
The work consisted of the construction of the complete lock, including the control building, lock gates and electromechanics. Throughout the construction of the lock chamber which took a year, the construction pit was kept dry by means of monitorable and controllable drainage. The 40-metre-long and 5.5-metre-wide lock has a drop of 1.16 m which bridges the difference in the height of the water level between the Lys and the Scheldt.

The pumped storage power plant Erzhausen in Lower Saxony in Germany was commissioned in 1964 after a ten-year construction phase by PreussenElektra (later called E.ON). At the beginning of 2009, Statkraft took over the pumped-storage power plant Erzhausen which has an installed capacity of 220 MW.
The yearly electricity generation is variable and dependent on the electricity demand. The pumped-storage power plant works with four Francis-Spiral turbines and is primarily used for peak power needs as well as to support the power frequency.
The central control room for monitoring and semi-automated operations of the run-of-river hydropower plants along the Weser, Werra, Fulda, Hunte and Eder is also located in the pumped storage power plant Erzhausen.


President Trump is seeking more than $75 million for work on the new Soo Lock project in Sault Ste. Marie. The U.S. Army Corps of Engineers says the money would be used to start construction of the upstream approach walls, continue the design of the New Soo Lock chamber, and finish construction of the upstream channel deepening. The Corps tells us the upstream approach walls will stabilize the existing approach walls to allow for modern vessels to tie up and wait their turn to pass through the new lock. It’s anticipated the wall designs will be finished in late 2019, and the construction contract will be awarded in summer 2020. Army Corp Lieutenant Colonel Greg Turner says the appropriation keeps the project on track for completion in seven to ten years from the start of construction.

W.A.C. Bennett Dam|
At W.A.C. Bennett Dam, differences in the spillway geometry between the physical hydraulic model from the 1960s and the prototype make it difficult to draw reliable conclusions on shock wave formation and chute capacity from physical model test results. The magnitude of shock waves in the concrete-lined spillway chute are strongly influenced by a 44% reduction in the chute width downstream of the three radial gates at the headworks, as well as the relative openings of the radial gates. The shock waves lead to locally higher water levels that have caused overtopping of the chute walls under certain historical operations.
Prototype spill tests for discharges up to 2,865 m3/s were performed in 2012 to provide surveyed water surface profiles along chute walls, 3D laser scans of the water surface in the chute and video of flow patterns for FLOW-3D model calibration. Excellent agreement was obtained between the numerical model and field observations, particularly for the location and height of the first shock wave at the chute walls (Figure 1).
Figure 1. Comparison between prototype observations and FLOW-3D for a spill discharge of 2,865 m^3/s at Bennett Dam spillway.
The calibrated FLOW-3D model confirmed that the design flood could be safely passed without overtopping the spillway chute walls as long as all three radial gates are opened as prescribed in existing operating orders with the outer gates open more than the inner gate.
The CFD model also provided insight into the concrete damage in the spillway chute. Cavitation indices computed from FLOW-3D simulation results were compared with empirical data from the USBR and found to be consistent with the historical performance of the spillway. The numerical analysis supported field inspections, which concluded that deterioration of the concrete conditions in the chute is likely not due to cavitation.
FLOW-3D was used to investigate poor approach conditions and uncertainties with the rating curves for Strathcona Dam spillway, which includes three vertical lift gates on the right abutment of the dam. The rating curves for Strathcona spillway were developed from a combination of empirical adjustments and limited physical hydraulic model testing in a flume that did not include geometry of the piers and abutments.
Numerical model testing and calibration was based on comparisons with prototype spill observations from 1982 when all three gates were fully open, resulting in a large depression in the water surface upstream of the leftmost bay (Figure 2). The approach flow to the leftmost bay is distorted by water flowing parallel to the dam axis and plunging over the concrete retaining wall adjacent to the upstream slope of the earthfill dam. The flow enters the other two bays much more smoothly. In addition to very similar flow patterns produced in the numerical model compared to the prototype, simulated water levels at the gate section matched 1982 field measurements to within 0.1 m.
Figure 2. Prototype observations and FLOW-3D results for a Strathcona Dam spill in 1982 with all three gates fully open.
The calibrated CFD model produces discharges within 5% of the spillway rating curve for the reservoir’s normal operating range with all gates fully open. However, at higher reservoir levels, which may occur during passage of large floods (as shown in Figure 3), the difference between simulated discharges and the rating curves are greater than 10% as the physical model testing with simplified geometry and empirical corrections did not adequately represent the complex approach flow patterns. The FLOW-3D model provided further insight into the accuracy of rating curves for individual bays, gated conditions and the transition between orifice and free surface flow.
Figure 3. FLOW-3D results for Strathcona Dam spillway with all gates fully open at an elevated reservoir level during passage of a large flood. Note the effects of poor approach conditions and pier overtopping at the leftmost bay.
John Hart Dam
The John Hart concrete dam will be modified to include a new free crest spillway to be situated between an existing gated spillway and a low level outlet structure that is currently under construction. Significant improvements in the design of the proposed spillway were made through a systematic optimization process using FLOW-3D.
The preliminary design of the free crest spillway was based on engineering hydraulic design guides. Concrete apron blocks are intended to protect the rock at the toe of the dam. A new right training wall will guide the flow from the new spillway towards the tailrace pool and protect the low level outlet structure from spillway discharges.
FLOW-3D model results for the initial and optimized design of the new spillway are shown in Figure 4. CFD analysis led to a 10% increase in discharge capacity, significant decrease in roadway impingement above the spillway crest and improved flow patterns including up to a 5 m reduction in water levels along the proposed right wall. Physical hydraulic model testing will be used to confirm the proposed design.
Figure 4. FLOW-3D model results for the preliminary and optimized layout of the proposed spillway at John Hart Dam.
BC Hydro has been using FLOW-3D to investigate a wide range of challenging hydraulics problems for different types of spillways and water conveyance structures leading to a greatly improved understanding of flow patterns and performance. Prototype data and reliable physical hydraulic model testing are used whenever possible to improve confidence in the numerical model results.

Tanzanian authorities are launching the filling of the reservoir of the Julius Nyerere hydroelectric dam on the Rufiji River. The facility will power the turbines of a 2,115 MW hydroelectric plant, one of the largest in East Africa.
News on the Rufiji hydroelectric project in Tanzania. Authorities in the East African country are beginning to impound the dam, which is being built in the heart of the Selous Game Reserve in the Pwani region, about 220 km by road southwest of the economic capital Dar es Salaam. The impoundment is a crucial step before the Stieglerâ€™s Gorge hydroelectric plant is commissioned.
Its basin will be able to hold 34 billion m3 of water thanks to a concrete dam in the shape of an arch, with a height of 134 m. Its reservoir will cover 1200 km2 in the middle of the Selous Reserve. The water flowing down from the dam will turn the turbines of a power plant with a capacity of 2,115 MW. The Tanzania Electricity Supply Company (TANESCO), which is implementing the project, estimates the annual capacity of the plant at 5,920 GWh.


CLA-VAL 131-CP : Electronic Interface Control Valve
The Model 131-CP Electronic Interface Control Valve is designed for applications where remote electronic control is required. It is a hydraulically operated, pilot controlled, diaphragm actuated control valve. These valves are typically used to provide process control, flow control, and/or pressure control across a variety of applications including: two-stage loading, bypass, pressure sustaining, or pressure reducing. The valve is equipped with two direct-acting two-way solenoids. These are hydraulically connected to the chamber of the valve, causing it to close or open under the control of a Cla-Val D22 Electronic Valve Controller or PLC. The 131-CP valve is a fail-safe valve equipped with a manual bypass feature and can also incorporate hydraulic override features.


Plans for repairs on the damaged Missouri River levees are finally under way. Nearly 100 days after the initial flood started, the U.S. Army Corps of Engineers announced that a $22.1 million contract has been awarded to Weston Solutions of West Chester, PA for initial breach repairs to the L550-561 levee system Tuesday.
In the USACE press release, they explained there are four levee breaches on levee L550 due to this year’s high runoff event. This initial breach repair will reduce the risk of flooding to help protect critical infrastructure along the Missouri River near Watson, Missouri.
“Within 100 days of the contractor beginning this initial breach repair work, both priority breaches on the L550 levee system should be closed,” said Rachel Shrader, Project Manager, Omaha District System Restoration Team. “These initial breach repairs will increase flood risk management to the area behind the levee as the team works on repair solutions for fully rehabilitating the levee system.”
More information coming soon on this story.

THIRUVANANTHAPURAM: As various districts in the state continue to receive torrential rain, the KSEB has opened a control room at its headquarters in Thiruvananthapuram, in addition to the Dam Safety Organisation office at Pallom in Kottayam, where the services of dam safety engineers have been made available to monitor all the 18 dams in the state round the clock. Facilities like satellite phones have also been set up in the control room to mitigate any of the public’s fears regarding the safety of the dams.
So far, 1,898.6mcm water has reached the 18 dams in the state as against the storage capacity of 3,532.5mcm. The Idukki Dam, the largest dam of the KSEB, has 54.12 per cent storage capacity. Similarly, the Idamalayar Dam has a capacity of 47.87 per cent, Kakki Dam 52.87 per cent, Banasura Sagar Dam 65.98 per cent, and Sholayar Dam 64.17 per cent. The total storage capacity of the KSEB’s dams is dependent on these five reservoirs.
The KSEB has informed that like any other monsoon season, the shutters of smaller dams like Peringalkuthu, Ponmudi, and Kakkayam, and comparatively smaller dams like Kallarkutty, Lower Periyar, Kallar, and Irattayar are being opened. It has also been issuing danger alerts according to the water level at the dams.


Dual Plate Check Valve
The valve that used to prevent backflow in a piping system is known as a check valve. It is also known as a non-return valve or NRV. The pressure of the fluid passing through a pipeline opens the valve, while any reversal of flow will close the valve. It allows full unobstructed flow and automatically shuts as pressure decreases. The exact operation will vary depending on the mechanism of valve.
The Dual Plate Check Valve design is the result of attempts to solve the problems associated with swing check valve and lift check valve. The Dual Plate Check Valve employs two spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by torsion spring action without requiring reverse flow.
This design offers the twin advantages of No Water Hammer and Non Slam simultaneously. All features put together make the Dual Plate Check Valve one of the most efficient design. It is also referred as SILENT CHECK VALVE
Types of Dual Plate Check Valve
The tilting disc check valve is designed to overcome some of the weaknesses of conventional swing check valves. The design of tilting disk enables the valve to open fully and remain steady at lower flow rates and close quickly when the forwarding flow stop. The dome-shaped disc floats in the flow and fluid flow on both bottom and top of disk surfaces. As the disk is spring loaded, when forward flow pressure reduces, the spring force helps valve to close fast. In the image above, you can see the flow from the valve.
Lift Check valves are particularly suitable for high-pressure service where the velocity of flow is high. The disk is perfectly set on the seat with full contact. They are suitable for installation in horizontal or vertical pipelines with upward flow.
Here you can see the plug or piston type and ball type check valve. These valves provide superior leak tight characteristics to those of swing check valves. Some design in plug type uses spring to retain the disk in closed position. This will ensure that valve allows flow only when there is enough pressure in the flow direction.


Once complete, Tehri PSP will be one of the largest pumped storage projects in the world.
During the detailed design, SMEC undertook redesign of two large outlet structures, converting them into four smaller structures to control velocity and provide more equitable distribution of flow. Extensive 3-D analysis of the underground caverns has ensured the safety of workers during construction, with rock bolting modelled in the analysis to replicate ground conditions.
The project is designed to generate 1,000 megawatts of electricity, which will help to meet the growing demand for power in the region. The project will also help to improve the reliability and stability of the power grid, reducing the risk of power outages and blackouts. The project aids management of water resources in the area, which will help to ensure that water is used efficiently and sustainably.
Overall, the Tehri Pump Storage Project is expected to have several positive impacts, including the generation of electricity, improved water management, employment opportunities, economic development, and flood control.
