Hoeven: Corps Awards $59 Million Contract for Red River Valley Flood Control Project
FARGO, N.D. – Senator John Hoeven released the following statement after the Army Corps of Engineers awarded a $59 million construction contract for the Fargo-Moorhead region’s flood protection project, the second construction contract awarded for the project. Today’s contract will build the Wild Rice River structure, which includes a concrete control structure with two gates. As a member of the Senate Energy and Water Appropriations Committee, Hoeven secured additional funding in the Corps construction account, enabling the Corps to fund priority construction projects like this.
`“This is a major step forward in the construction of permanent flood protection for the Red River Valley,” said Senator Hoeven. “As a member of the Senate Energy and Water Appropriations Committee, I worked to provide the Corps with additional construction funding to enable the Corps to fund important priorities like flood protection for the Fargo-Moorhead region. This contract continues construction and will build the control structure on the Wild Rice River, which is an important component of the flood protection project.”
Hoeven has worked to secure authorization and funding for the permanent flood protection project in the Red River Valley, including project authorization, the new construction start, the Project Partnership Agreement with an increased federal funding level of $750 million, EPA approval to apply for a Water Infrastructure Finance and Innovation Act (WIFIA) loan and other milestones.
The senator continues working as a member of the Energy and Water Development Appropriations Committee to secure funding that will help reduce local costs. To this end, Hoeven included the following priorities in the Senate’s Fiscal Year (FY) 2020 funding legislation:
- Construction Funding: Provides $233 million in funding above the President’s request for construction of flood control projects. These funds are not allocated to a specific project and will be available to support Corps priorities in the FY2020 work plan, which will be released approximately 30 days after the FY20 Energy and Water appropriations bill is signed into law. This increase will empower the Corps to support more of its priorities, like comprehensive flood protection for the Fargo-Moorhead region.
- Funding for P3 Projects: Provides $100 million for construction in a new account for “Alternative Delivery” projects, including public-private-partnership (P3) projects and split delivery projects. Fargo-Moorhead would be eligible for funding from this account in addition to the construction funding the bill provides above the budget request for flood control projects.
- This is a result of Hoeven’s work to provide direct funding for P3s. P3s represent a new type of financing model for the Army Corps of Engineers and have not been included in previous budget requests

ACV300 No-Slamming hydraulic check valve is a kind of slow-closing check valve which consists of the main valve, check valve, needle valve, ball valve, microform filter, and pressure gauge. Using hydraulic automatic operation, it can make the main valve get the best opening and closing speed. Prevent water hammer caused by valve slamming at closing, in order to achieve the effect of slow closing and silencing.
Installation and Adjustment Hydraulic Check Valve
- The best installation direction of the main valve is horizontally mounted on the pipeline with the valve cover facing upward.
- Before installation, we should remove debris from the pipeline, and pay attention to the arrow markings on the main valve body when installing, the arrow represents the direction of water flow.
- The upstream of the main valve should install a gate valve and a filter valve, and a gate valve should also be installed downstream for maintenance purposes.
- The pipeline must be completely blown and cleaned before the water is turned on, so as to discharge impurities, iron particles, and other solid particles outside the pipe.
- When testing water, slowly open the gate valve inlet of the main valve and slowly increase the pressure, while paying attention to whether the control tubing outside the main valve body is leaking.
- The microfilter on the main valve is mainly used to clean the needle valve. The needle valve and ball valve with adjustment can get the best performance of opening and closing speed.

Description for Gibe II Hydropower Plant (Ethiopia)
Gibe II hydropower plant is the second stage of the Gibe-Omo hydroelectric cascade which includes Gibe I and Gibe III (all in operation), Koysha (under construction) and Gibe V (planned). Gibe II has a total capacity of 420 MW and an energy production of 1’625 GWh/y.
The project was promoted by the Ethiopian Government to develop the hydropower potential of the Omo/Gibe river, a huge programme to improve substantially the power supply of the country.
Gibe II includes Africa’s longest hydraulic tunnel, more than 25 km long below the Fofa mountains, which requested major technical efforts and was one of the biggest challenges faced by our engineers to date.
The inlet area is located along the Gilgel Gibe river. A concrete gravity dam with an intake tower allows the diversion of a flow of about 105 m3/s inside the power tunnel, which delivers the flows through the penstocks to the powerhouse in the Omo river valley, the outlet area.
In order to face the silting of the reservoir, a desilting weir is foreseen upstream of the dam to create an impounding to store the sediments.
The dam is a classical concrete gravity structure with a straight axis. The spillway is located on the central blocks, including an uncontrolled overflow crest and a flip bucket (ski jump) energy dissipator device.
The bottom outlet, embedded in the dam body, is controlled by two sliding gates in series. This structure is especially designed, allowing the rising of the sill through stoplogs, to deal with the silting of the reservoir.
The project also included a river diversion canal on the right bank and two culverts in the weir structure close to the right abutment. Temporary upstream and downstream cofferdams completed the protection against flooding the dam area of permanent works.
In the outlet area we observe the surge shaft, a cylindrical structure with a throttle at the tunnel end. Two long steel penstocks end into a manifold with a bifurcation from two to four conduits, one for each turbine.
The power house is a conventional surface outdoor type with vertical axis units, located on the right bank of the Omo river. The structure is divided in five bays housing 4 Pelton turbines and the erection bay, while the control room finds place in the superstructure. The step-up transformers are located outdoor on a riverside deck.
The 400 kV lines are anchored in the excavation front behind power house, and connect the transformers outcoming lines cross the river going towards the switchyard.
- Gravity Dam ( H = 49 m, L = 140 m )
- Main Roads ( 65 km )
- Power Tunnel ( L = 25.8 km, D = 6 m )
- Penstocks ( No. 2, L = 1.1 km, D = 3.6 ÷ 2.8 m )
- Surge Shaft ( H = 95.5 m, D = 18 m )
- Outdoor Power House ( No. 4 Pelton turbines IP = 4x105 MW )
- 400 kV Switchyard
- Main Roads ( 65 km )
Examples of engineering challenges
One of the most evident examples of value engineering and design optimization is the construction of the power tunnel characterized by a wide range of geological conditions. The excavation was carried out by a double shield TBM having a boring diameter of 7 m, which erected precast concrete segment lining.
The lining, because of the relatively severe load conditions, was designed to bear the significant overburden reaching a maximum of approx. 1’400 m.
A second engineering challenge was the diversion of the river flows in the dam area, during the project construction, in the narrow and steep longitudinal section of the valley. The river diversion was achieved through a culvert (currently operating as bottom outlet) along with low blocks in the spillway structure which allowed a safe discharge of large floods up to 2’325 m3/s.

KUCHING, Aug 10: The Sarawak government has agreed to fund and run Phase Four of the Sibu flood mitigation project with an estimated cost of RM120 million under the 12th Malaysia Plan.
In a statement, Senator Robert Lau revealed the last phase of the project involves the building of a pump station next to Paramount Hotel and the raising of road level along the remaining stretch of Jalan Lanang to act as a bund, linking the previous phases together which were funded by the federal government.
“The flood mitigation project for Sibu started in 2008 and involved the building of bunds by raising the road level along the rivers and building pumping stations and retention ponds.
“Phase One and Two have been completed with the road level from Upper Lanang to junction of Jalan Lanang, Jalan Ek Dee and three pumping stations built.
“Two more pumping stations were built under the federal stimulus package a few years ago,” Lau disclosed.
He added that Phase Three of the project is ongoing and is expected to be completed in 2022. It involves the building of two pump stations and the raising of road level along the village beside Igan River.
Meanwhile, Sarawak Department of Irrigation and Drainage director Datuk Chok Mok Soon asserted that the building of bunds is a tried and tested method in effectively preventing river water from overflowing into low-lying areas.
“Low-lying areas of Sibu land level is 2.5 metres while the water level of Rajang River during high tide range from 2.2 to 2.8 metres.
“When there is heavy rainfall during high tide, the low-lying areas will be flooded. The bund will act as a barrier to the high tide water from flowing into the low-lying areas and at the same time, the pumps will pump out the rain water.
“There will be retention ponds behind the pumping stations to store excess rain water before the pumps can clear them,” Chok added. — DayakDaily

two power stations in the enterprise, Framfuste and Øyberget power stations, were completed and commissioned in 2005. The picture was taken during the construction period at Framruste power station.
Øvre Otta strongly dominated the news when Stortinget enacted the law to develop the project in 1999. Stortinget reduced the contractors’ original plans by half, so that the development will yield an annual production of 525 GWh.
The projecting of Øvre Otta started in 1992, and the application for concession was submitted in 1996. The King in Council granted concession for the development in September 2001.
An old dam
Framruste power station utilises the head between the already existing Raudalsmagasinet (the Raudal dam) in Skjåk Municipality, and Lake Pollsvatnet in Øvre Otta. The head is 325m.
The Raudal dam was constructed in the 1940s in order to increase the winter discharge in the lower part of Glomma. The dam is 41 m high, and the storage capacity is 166 million m3 of water.
The water is carried in a tunnel to Framruste power station. The power station is built inside the mountain south of the Framruste river. The water is transferred from the power station into Øvre Otta in Pollenvatnet downstream from Pollfossen waterfall.
An environmentally friendly project
The development of Øvre Otta appears to be an environmentally friendly power project par excellence. An already existing reservoir is utilised, and both power stations are constructed near roads. The impact on nature has been limited.

|Abstract:||Flows and water levels within and approaching the Morganza Control Structure Forebay were investigated with an Adaptive Hydraulics model. The model was used to evaluate the influence of the potato ridge and lower guide levee grades on energy losses and flow patterns within the forebay. The diversion discharge capacity of the Morganza Control Structure is sensitive to computed water levels in the forebay and to estimated water levels at the entrance to the Morganza Floodway. Computed water levels in the forebay are determined by Mississippi River stages and energy losses across the potato ridge and within the forebay. The model simulated Morganza Control Structure operations and diversion discharge under two soft opening scenarios for a provisional project design flood hydrograph. The model demonstrates the potential impacts of the potato ridge grade on the discharge capacity of the Morganza Control Structure. The Adaptive Hydraulics code was modified to permit computation of individual gate discharges based on available operating head across the structure. Additional code enhancements are needed to simplify specification of structure operating rules. These modifications will support future coupling of this model with the Morganza Floodway model and development of a similar coupled model for the Old River Control Complex.|

LAHORE: The construction work on 21MW Tangir Hydropower Project, meant for providing electricity to the people in various areas during construction phase of Diamer Bhasha Dam, has commenced, according to the Water and Power Development Authority (Wapda).
The construction works on eight sites of Diamer Bhasha Dam and nine of the Dasu Hydropower projects are also underway these days on a fast-track basis.
Bhasha Dam project sites where the construction work was going on include access tunnel, access roads, upstream and downstream cable bridges, a senior official told Wapda Chairman retired Lt Gen Muzammil Hussain who visited the area on Wednesday.
During the visit, the Wapda chairman reviewed construction work on Bhasha as well as Tangir hydropower projects.
Speaking on the occasion, the Wapda chief said that construction work on Bhasha Dam was progressing despite the Covid-19 pandemic. He, however, maintained that the project authorities must ensure achieving major construction milestones in accordance with the timelines set for this purpose.
Gen Hussain opened the newly-constructed cable way bridge across River Indus. Rest of three such bridges are scheduled to be completed in April and May one after the other for swift mobilisation on both banks of the river during high-flow season.
Pontoon bridge across the River Indus had already been completed ahead of schedule in December last year to facilitate mobilisation of machinery and workforce during the current low-flow season.
Diamer Bhasha Dam will have a gross water storage capacity of 8.1 MAF to irrigate 1.23 million acres of additional land. With installed power generation capacity of 4,500 MW, the project will provide more than 18 billion units per annum to the National Grid.
Earlier, the Wapda chairman witnessed construction activities on Dasu Hydropower Project Stage-I, being built across River Indus upstream Dasu town in Kohistan District of Khyber Pakhtunkhwa. During the briefing about progress on the project, he was informed that the construction work on nine different sites is in progress.
He was told that river diversion works are expected to be completed by the end of this year. Afterwards, the mighty Indus would pass through the two diversion tunnels paving the way for construction of the main dam.
The Dasu Hydropower Project will be completed in two stages. Wapda is currently working on 2,160 MW-Stage-I, likely to be completed in 2025.The Stage-I will provide 12bn green and low-cost electricity to the national grid annually while the Stage-II will also contribute another 9bn units per annum.

Dubossary Hydroelectric Power Station
Dubăsari (Transnistria), Moldova
Located on at the Dniester River near Dubăsari in Transnistria, Moldova, the installed capacity of the hydroelectric power station is 48 mW. Originally constructed in the 1950s, the power station began to show serious cracks in the concrete structures. The number of leaks, corrosion of metal structures, pipes and main galleries, inspection galleries and in the power generation equipment put continued operation of the power plant in danger.
The PENEPLUG rapid-setting compound was used to immediately stop any active leaks; PENETRON crystalline waterproofing material was applied to restore impermeability of the concrete and PENECRETE MORTAR filled and sealed the concrete joints. All repair work was done inside the concrete body of the Dubossary Dam.

South Africa set to construct Phase1 of Mzimvubu water project
South Africa is set to embark solely on phase1 of Mzimvubu water project by South African companies despite the Chinese government given a go-ahead to invest.
Minister Water and Sanitation, Gugile Nkwinti, said: “Work on the project is expected to start in January 2019 with the department having already set aside a budget for the construction of the dam in the 2019/2020 financial,” said Gugile Nkwinti.
Mzimvubu water project has two multi-purpose dams on the Tsitsa River, a major tributary to the Mzimvubu River. To make the scheme sustainable throughout its life, the two dams will be operated and built as one integrated scheme. Phase one of the Mzimvubu River catchment will be built by the integrated scheme.
The project is estimated to cost US $1.1bn. Although the construction is dependent on availability of funds, it is estimated that the project will not take less than seven years.
According to Trevor Balzer, Deputy Director General: Strategic and Emergency projects in the department, it’s estimated that 6700 jobs will be created during the construction and an additional 600 jobs during the catchment rehabilitation. He further added that the use of local suppliers and local employment is central to the success of the Mzimvubu project.
A new dam at Ntabelanga on the Tsitsa River will also be built as result of the project. The dam will have a storage capacity of ±490 million cubic metres. It will also include a hydropower plant that generates 7MW of power.

Principle of Water Level Sensor
Water level sensor is a kind of sensor which can detect water level. It is mainly used in medical, food and chemical industries to control water level and detect water level. There are many kinds of water level sensors, including single flange hydrostatic/double flange differential pressure water level sensor, floating ball water level sensor, magnetic water level sensor, input water level sensor, electric inner floating ball water level sensor, electric buoy water level sensor, capacitive water level sensor, magnetostrictive water level sensor, servo water level sensor, ultrasonic water level sensor, radar water level sensor, etc. Sensors, etc. The working principles of different water level sensors are different, and their applicability is different.
This paper briefly introduces the principles of these water level sensors. Buoy type water level transmitter is to change magnetic buoy into buoy. Water level sensor is designed according to Archimedes buoyancy principle. Buoy-type water level transmitter is used to measure the water level, boundary or density of liquid by means of tiny metal film strain sensing technology. It can be operated by the on-site buttons to perform routine setting operation. Floating ball water level transmitter consists of magnetic float ball, measuring duct, signal unit, electronic unit, junction box and installation parts. Generally, the proportion of magnetic float ball is less than 0.5. It can float above the liquid surface and move up and down along the measuring duct. There are measuring elements in the duct. It can convert the measured water level signal into resistance signal proportional to the change of water level under the action of external magnetic field and electronics. The unit is converted into signal output. Because the float switch is the simplest and oldest detection method, it has the disadvantage of inaccurate water level detection, and the float is easy to get stuck.
The hydrostatic water level sensor works on the principle of hydrostatic pressure measurement. It usually uses silicon pressure sensor to convert the measured pressure into electrical signal, which is amplified and compensated by amplifier circuit. Finally, it is output by 4-20 mA or 0-10 mA current mode.
The ultrasonic water level sensor is generated by the vibration of the transducer wafer under the excitation of voltage. When the ultrasonic wave touches the liquid, it will produce a significant reflection and form an echo. Therefore, the ultrasonic wave is used as a means of detection to produce and receive the ultrasonic wave. This is the working principle of the ultrasonic water level sensor. The characteristics of the ultrasonic water level sensor are: high frequency, short wavelength, small diffraction phenomenon, especially good direction, and it can be directed as a ray. Photoelectric liquid level sensor is a new type of contact point liquid level measurement and control device based on the principle that light reflects and refracts at the interface of two different media. Photoelectric water level sensor has many advantages, such as simple structure, high positioning accuracy, no mechanical parts, no debugging, high sensitivity, corrosion resistance, low power consumption, small size, etc. It also has the characteristics of high temperature resistance, high pressure resistance, strong corrosion resistance, stable chemical properties, and little impact on the measured medium.
Photoelectric water level sensor has a wide range of applications, high detection accuracy, long life and strong stability, so it is suitable for many aspects. Next, we will focus on the photoelectric liquid level sensor. Photoelectric water level sensor is a new type of contact point water level measurement and control device based on the principle that light reflects and refracts at the interface of two different media. It has many advantages such as simple structure, high positioning accuracy, no mechanical parts, no debugging, high sensitivity and corrosion resistance, less power consumption, small size and so on, which are gradually recognized by the market. Because the output of water level is only related to whether the photoelectric probe contacts the liquid level or not, and has nothing to do with other characteristics of the medium, such as temperature, pressure, density, electricity and other parameters, the photoelectric water level sensor has accurate detection, high repetition accuracy, fast response speed, very accurate liquid level control, and no need to adjust. Also it can be directly installed and used.
Because the photoelectric water level sensor probe is relatively compact, it can be separately installed in a narrow space for special tanks or containers. In addition, a number of photoelectric probes can be installed on a measuring body to make a multi-point water level sensor.
Because there are no mechanical moving parts in the photoelectric level switch, the photoelectric level sensor has high reliability, long life and maintenance-free. And because the principle of optical reflection is used to detect, photoelectric water level sensor is affected by scale, impurities, liquid corrosion and so on.
