As many as 1,079 people from 350 families were shifted to relief camps from Peermade, Idukki, and Udumbanchola taluks, said the minister. He was speaking after a review meeting to assess the arrangements made for the opening of the dam.
Earlier in the day, the minister said he is hopeful the SC will rule in the state’s favour when it resumes hearing of the case. He said the apex court has asked Kerala
to submit a detailed affidavit about the new rule curve prepared by Tamil Nadu."Now we hope we can submit the actual details and condition about the dam before the court," he said.
The water level at Mullaperiyar dam was 138.20ft at6 pm on Thursday. As the upper rule curve has been fixed at 138ft till October 31, the dam shutters will be closed when the water level drops to 138ft. The shutters of Idukki dam which were closed on Wednesday will also be opened as the water level has been rising in the reservoir as well. A KSEB
official said the dam shutters will be opened on Friday or Saturday. "The water level is already nearing red alert level," he said, adding that up to 100 million cubic metres per second of water will be released. The water level at Idukki dam was 2,398.30ft on Thursday. The red alert is issued when it reaches 2,398.31ft while the upper rule level has been fixed at 2,399.31ft.

The infectious agent Hantavirus was first identified in the Hantan River area by Dr. Lee Ho-wang. Because his original publications transliterated the river's name idiosyncratically as "Hantaan," this spelling remains associated with the "Hantaan virus." In 2007 construction of the Hantangang Dam began on its lower course. It is expected to be complete in mid-2015. The sole purpose of the dam is flood control.


We worked on the expansion of the existing McCusker Gill. Inc. (MG) facility to include the construction of a new warehouse storage facility. The building is one-story, primarily used for material storage. In addition to the building and reconfigured and expanded parking, construction included landscaping improvements, other associated utilities, and a stormwater management system.
Challenges included high groundwater, the design of a complex stormwater drainage system with three (3) subsurface infiltration systems, and the construction of a restoration area within the 100’ inner riparian zone of the Old Swamp River. The project also involved connecting to the existing 8-inch water main stub on an abutting property, extending the warehouse and parking lot extension, and connecting to the existing watermain. A permitted sewer connection to the Town of Weymouth Sewer system was also completed for the increased flow from the new warehouse, which involved coordination with an abutting town to the subject property.

Coupled Aquifer-Borehole Simulation
A model coupling fluid hydraulics in a borehole with fluid flow in an aquifer is developed in this paper. Conservation of momentum is used to create a one-dimensional steady-state model of vertical flow in an open borehole combined with radially symmetric flow in an aquifer and with inflow to the well through the wellbore screen. Both laminar and turbulent wellbore conditions are treated. The influence of inflow through the wellbore screen on vertical flow in the wellbore is included, using a relation developed by Siwoń (1987). The influence of inflow reduces the predicted vertical variation in head up to 15% compared to a calculation of head losses due to fluid acceleration and the conventional Colebrook-White formulation of friction losses in a circular pipe. The wellbore flow model is embedded into the MODFLOW-2000 ground water flow code. The nonlinear conservation of momentum equations are iteratively linearized to calculate the conductance terms for vertical flow in the wellbore. The resulting simulations agree favorably with previously published results when the model is adjusted to meet the assumptions of the previous coupled models.

State utility Dubai Electricity & Water Authority (Dewa) has extended the bid submission deadline for the planned Hatta pumped storage project to 13 January 2019.
The client has extended the deadline from 18 November to give bidders more time to work on proposals, according to sources close to the project. The pumped storage project is planned to have a generation capacity of 250MW.
In June last year, Dewa awarded a AED58m ($15.8m) contract to France’s EDF to provide consultancy services for the pumped-storage project. The state utility announced this week that EDF had completed engineering studies for the proposed project, including design, geological, hydro-geological, environmental, geotechnical and deep excavation studies.
The hydro project will use water stored in the Hatta Dam, near the Oman border. The existing Hatta Dam can store up to 1,716 million gallons of water. The project will involve the construction of an upper reservoir, which will be able to hold up to 880 million gallons. The upper reservoir will be located 300 metres above the dam level.
During off-peak hours, turbines will use solar energy to pump water from the dam to the upper reservoir. The project will support the AED1.3bn ($354m) Hatta development plan, which was announced last November.
The appeal of pumped storage is that it can be integrated with different renewable energy sources like wind and solar power – power supply options that are intermittently affected by wind patterns and cloud cover. Pumped storage is an important source for energy storage as water is stockpiled when excess energy is produced. This can then be used to provide electricity when energy demand is highest during peak hours.


Pakistan's federal government approved the 969 MW Neelum-Jhelum hydropower project at a cost of PKR128.4 billion in Pakistan-controlled Kashmir. The project will be built by a consortium consisting of China Gezhouba Group Corp. (CGGC) and CMEC China. The Water and Power Development Authority (WAPDA) had already approved award of the contract to the CGGC-CMEC joint venture in March 2007 at the contract price of PKR90.9 billion. The project will also be executed through Neelum-Jhelum Project Co., a government-owned unit, which has since been set up and the debt ratio of the project will be around 50/50. The project envisages the diversion of the Neelum river at Nosairi in Azad Jammu and Kashmir, through a 32.5 km headrace tunnel to a power station. Three tunnels would be built under the project design: the first two would be 15 km long and 40 square metres and the second would be 17 km long and 80 square metres. The project will be completed in eight years. Read E-News Weekly 2/2006.

Parliamentary Secretary for Water Resources told National Assembly that government has priortised the construction of big storage dams to overcome the water shortages. He assured the house that construction work on Mohanand Dam on the River Sawat is in progress and shall be completed within the stipulated time. Total cost of dam is Rs.309 billion, having an active water storage capacity of 1.594 million cubic meters. The electricity generation potential is 800 megawatts. Two canals shall be extracted to provide irrigation to 15,100 acres of cultivable land.
Next in line for construction is Diymer Basha Dam on the River Indus upstream Tarbella. The estimated cost of the dam is Rs.525 billion. Live water storage capacity of dam’s reservoir is 8.1 million acre feet and electricity generation potential is 4500 megawatts. The construction of this dam will de-accelerate the silting process in the reservoir of downstream Tarbella dam, prolonging its estimated life. Hopefully, foreign funding shall be obtained to start construction work in the near future.
The most beneficial water conservation project for both irrigation and power generation is Kalabagh dam. But unfortunately it has been made politically controversial. The political leadership has lost interest in building consensus on this dam, which will bring green revolution by boosting agriculture production both Punjab and Khyber Pukhtunkhwa. It merits mention that feasibility studies for the construction of Kurran Tangi Dam on the River Kurram have been completed. Like the Mohammand Dam, it can be completed within five to six years’ time and federal government may not face much difficulty to acquire foreign funding, preferably from multilateral donors such as the World Bank and Asian Development Bank in the shape soft loans. Pakistan has already become a water scarce country and will certainly face unmanageable water shortages by 2025 if big and medium storage dams are not built. The present government is cognizant of this looming threat of water starvation. It seems worthwhile that +sufficient financial resources have to be arranged for the construction of storage dams before the country lands into acute water shortages. The deliberate policy of neglecting water conservation by the past elected governments had accrued losses of billions of dollars to the economy in the shape wasting precious water resources and declining production of agriculture.


The Waitaki river is the major river of the Mackenzie Basin, a large intermontane basin running between the Southern Alps and the Waimate foothills that forms the headwaters of the Waitaki River catchment. Fed by three large glacial lakes, Tekapo, Ohau as well as Lake Pukaki, the Waitaki River flows through Lake Waitaki, Lake Benmore and Lake Aviemore, the latter two contained by Benmore Dam and Aviemore Dam respectively. There several tributaries, notably the Ahuriri River and the Hakataramea River. It passes Kurow and Glenavy before completing its 110km journey and entering the Pacific Ocean between Timaru and Oamaru on the east coast.
The Waitaki River has New Zealand’s fourth largest flow with a mean flow (1927 -2000) at the Waitaki Dam of 359 cumecs. The river’s flow is normally low in winter, increasing in spring when the snow from the Southern Alps melts. Summer flows are dependent on rainfall, and generally decline during autumn as smaller streams in the catchment begin to freeze. The glacial lakes dampen flood peaks and modifies flood flows into the lower catchment. This natural storage, together with the control of lake levels by hydro-electricity development, regulates downstream flow. The median flow of the Waitaki River at Kurow is 356 cumecs.

Aswan high dam project is found in Egypt near the country’s border with Sudan, and it is one of the biggest multipurpose river projects in Africa, together with lake Nasser, the man-made lake behind the dam. There are two dams at Aswan and both have power stations. The first dam was constructed in 1902 at Aswan to confront flooding. This was totally inadequate and in 1956 a new dam was set up south of Aswan called the Aswan high dam.
The Aswan high dam was completed in 1970. It is 3600m long and 111m high. At the top, it is 40m wide and at its base, it is almost a km wide. Behind the dam is lake Nesser (500km long nearly 150km into Sudan.
The following are factors that have favored the establishment of the Aswan high dam in Egypt:
- The presence of skilled and unskilled cheap labor used in the construction of the dam project, especially from abroad, and cheap labor was provided mainly by Egyptian citizens.
- A supportive government policy to develop multi-purpose schemes to promote economic growth such as by mobilizing funds for the construction and encouraging investors.
- The presence of the Nile river with a large volume of water, that is sufficient water supply to generate hydroelectric power.
- Seasonal floods of the river Nile made it necessary to control floods by constructing a dam.
- presence of a fast flow of water to turn the turbines for generating hydroelectric power
- The presence of narrow gorges which offer a suitable site for river damming and which also increases the water pressure behind the dam for generating hydroelectric power.
- presence of hard basement rock, which offered the firm foundation for the construction of the dam
- Little and unreliable rainfall which necessitated the storing of water for use during the dry season
- A large tract of land to accommodate the reservoir / man-made lake upstream.
- This is due to the sparse population in the area allowing easy compensation of displaced people.
- The need to provide hydroelectric power for domestic and industrial use. There was a large market for hydroelectricity.
- presence of adequate capital for the construction of the project from the government of Egypt
- High level of technology used in setting up the project such as the use of large turbines to produce quality work.


In Khabarovsk Territory the metal structures of the additional fire water tank with a capacity of 5 thou m3 (VST-5000) have been installed at oil pumping station (PS) No. 34 of the II stage of the Eastern Siberia — Pacific Ocean trunk pipeline (ESPO-2).
The construction is underway as part of the implementation of the project to increase the delivery capacity of the ESPO-2, which envisages the construction of new and the revamping of existing oil pumping stations. The project is to be finished by 2020, which will be followed by the pipeline’s capacity being increased up to 50 million tons of oil per year.
The construction began in May 2018 as part of revamping PS 34 and is scheduled to be completed this fall. Apart from the construction of VST-5000, which will raise the level of fire safety at the station as the capacity of the ESPO-2 increases, the Company will further fit out the existing emergency water discharge tanks with additional discharge pipelines complete with a load compensation system, check valves, safety and emergency valves.
At present, PS No. 34 is building foundations for the additional pipeline of the 2nd of two emergency discharge tanks with a capacity of 5 thou m3.
At the same time in Primorye Territory two fire water tanks with a capacity of 3 thou m3 each are being built on the revamped PS No. 41. Works are being done on the arrangement of a hydrophobic layer on one of the tanks; metal structures are being installed on the other.
As part of the investment project, PS-29 was built to increase the capacity of the ESPO-2 in Arkhara District of Amur Region. The existing PSs No.34, 41 and 27 are being revamped (Oktyabrsky District of Amur Region), PS No.23 (Madagachinsky), PS No.26 (Seryshevsky District of Amur Region) as well as PS No.32 (Smidovichsky District of Jewish Autonomous Region) are being constructed.
The new PSs are booster stations without a tank farm for oil storage. They will ensure the necessary pressure inside the oil pipeline to pump additional volumes of oil. The installation of the new stations began in December 2017, the construction is to be completed in the fall of 2019. The construction is carried out by PMC ESPO (a subsidiary of Transneft), the stations will be operated by Transneft Far East, which ensures oil pumping via the ESPO-2.

The Tsubawara Dam, also known as the Tsubakihara Dam, is a gravity dam on the Shō River about 5 km (3.1 mi) north of Shirakawa in Gifu Prefecture, Japan. It was constructed between 1952 and 1953. The dam has an associated 107 MW hydroelectric power station which was built in two parts. The first part of the power station was commissioned in 1954 and the second part of the power station was commissioned in 1975. Of the nine dams on the Shō River it is the seventh furthest downstream.

Due to unfavorable weather conditions, the scuba diver that was scheduled to be in Capital Lake on Friday, September 8, has been postponed until Monday September 11, weather permitting. The scuba diver will be in Capital Lake for the purpose of locating and temporarily plugging a stormwater outfall pipe in order to complete construction of the 7th Avenue Flood Mitigation project. The overall project is expected to be complete by mid-September, 2017. When finished, this project will significantly reduce the number of flooding occurrences during major storm events and when Capital Lake levels are high.


Victoria Embankment – New River Thames Mooring Facility – Flood Wall
Woods River Cruises appointed Amicus to undertake concrete works at their new mooring facility along the Victoria Embankment at Waterloo Bridge.
The location provided many challenges. Not only in the centre of London but also access was required across the busy cycle way and the embankment footpath which had to remain open for the general public at all times.
The works involved the demolition of the existing flood defence wall which had to be coordinated with the construction of a new RC concrete flood wall so that flood protection was maintained.
Once demolition was completed new RC pads were constructed for the new access brow, steel steps and ramps.
Works also included the relaying of large yorkstone paving slabs at the eastern brow location.

KUCHING: The construction of the main dam of the 1,285MW Baleh hydroelectric project in central Sarawak will start soon, according to Sarawak Energy Bhd (SEB).
This follows the completion of the project’s dual diversion tunnels, river diversion and closure works last month.
The 1.2km diversion tunnels would enable river diversion activities, which are now fully functional.
“With the simultaneous completion of the diversion tunnels and the cofferdam construction in October, we are able to start the construction of the main dam, ” said SEB project delivery executive vice-president Pramod Kumar Karunakaran.
The river goes through the diversion tunnels to enable the closure of a stretch of the upper Baleh River.
Pramod noted that the construction of the closure berm or rock layer across the upper Baleh river would continue till the safe elevation of 71m in a month.
Once completed, the construction of the 188m concrete face rockfill dam will commence.
“The project is expected to employ 3,500 workers at the peak of construction works, ” he added.
The Baleh dam, which is SEB’s largest hydropower project to date, is estimated at RM8bil. It is due for commissioning in 2026.
The dam site catchment is expected to cover an area of some 5,625 sq km and will run to the Sarawak-Kalimantan border.
The project is divided into six packages, including the diversion tunnels which are the crucial components.
The other packages include jetties, roads and bridges, storage for explosive magazines used for rock blasting, an operator’s village, main civil, electrical and mechanical works.
The Baleh dam is located in the interior of the Hulu Rajang parliamentary constituency in the upper Rejang Basin, which is home to the 2,400MW Bakun dam (firm energy of 1,771MW) and 944MW Murum dam (635MW).
State-owned SEB acquired the Bakun dam from the federal government three years ago.
When the Baleh dam is operational, the three dams will have a combined electricity generation capacity of 4,540MW to power particularly the energy intensive industries in Sarawak Corridor of Renewable Energy (SCORE).
The energy from Bakun and Murum dams (pic) are supplied via the Sarawak grid to Samalaju Industrial Park, which houses energy-intensive heavy industries such as aluminium and ferroalloy smelting plants.The Baleh dam is to power Sarawak’s next wave of industrial development that includes a major steel plant in the region.
The base load demand of energy in SCORE is expected to increase to 2,550MW and reach 3,700MW by 2025.
Pramod pointed out that rest houses were built on the opposite banks of the river diversion tunnels with boat landing facilities.
Meanwhile, SEB group CEO Datuk Sharbini Suhaili said the Baleh dam would contribute to maintaining the company’s status as Malaysia’s largest renewable energy provider.
“The project involves multiple stakeholders with different needs.
“To balance the needs, the support from the government and communities has been crucial for SEB’s completion target for the diversion tunnels.
“This is also critical to meet the current commissioning target of the dam by 2026, ” he added.
Hulu Rajang MP Datuk Wilson Ugak Kumbong said as the country’s powerhouse, his constituency has the potential to light up the proposed new Indonesian capital in east Kalimantan.
SEB has been selling electricity to neighbouring west Kalimantan via the Indonesian power utility.
The company also plans to export power to Brunei Darussalam and Sabah.

In order to allow the hydraulic performance of type TS65-40-125 centrifugal pump with a medium specific speed to satisfy multioperatingcondition simultaneously, its impeller was redesigned three times by means of the enlarged design flow rate method. A structure grid was generated in Ansys Workbench 12 and the grid sizeindependence was analyzed. The pressure, turbulence kinetic energy, velocity distributions in those impellers and the overall performance curves were obtained with the commercial software CFX. Finally, one optimal impeller was identified and experiments were made against it. It can be concluded that the properly selected geometry parameters of the impeller can effectively improve head and efficiency of the centrifugal pump with medium specific speed and expand the high efficiency zone by using the enlarge design flow rate method. The head of the redesigned pump was improved as high as 5 m compared with the original one at the design point and the efficiency at five operating points basically met the specifications in the related national pump standard of China. Some references are provided for the multioperatingcondition design of centrifugal pump with medium specific speed.

With the water level at the Bhavanisagar Dam approaching the Full Reservoir Level (FRL) of 105 feet, the flow was increased to 8,000 cusecs on Monday.
At 4:00 p.m., the inflow into the reservoir was 4,972 cusecs while the water level rose to 103.62 feet. The storage was 31.64 billion cubic feet (mtc) against a capacity of 32.80 mtc. The flow was 6500 cusecs in the Bhavani River and 1500 cusecs in the Lower Bhavani Project (LBP) canal. The discharge into the Kalingarayan Canal and Arakankottai-Thadapalli Canals was halted due to rain.
An official from the Department of Public Works said that since the inflow is expected to increase due to rain in the catchment areas, the flow has been increased to prevent flooding into the river. “Currently, the excess water is discharged from the weirs into the Bhavani River,” they added.
Since the flow would increase more with the influx, people living in low-lying areas and along the river banks were urged to move to safer places. In addition, people were warned not to enter the river or wash their clothes or livestock. The tax authorities, with the help of tam-tam, continue to issue warnings to people living along the river in the Sathyamangalam and Gobichettipalayam taluks.

About four months after construction began, we have witnessed a transformation of the original intake shaft and platform. In September 2011, this area served as the reception area for the official Groundbreaking Ceremony for the Calaveras Dam Replacement Project.
The new intake shaft will be built adjacent to the existing intake shaft with a depth of 150 feet. The soil nail wall is currently being constructed to support the soil surrounding the future intake shaft. The architectural design of the new intake tower will replicate the design of the original tower built in 1925. Tunnels will be constructed to connect the existing water lines to the new intake shaft. The gravity fed system will send water from the Calaveras reservoir to the Sunol Valley Treatment Plant, eventually becoming our drinking water.

Construction is about to start on a new pump station at the Darwin River Dam, 70 km south of the Northern Territory capital.
The territory’s water utility, Power and Water, has awarded the design and construction contract to civil contractor, McMahon Services Australia (NT), part of a privately owned company with 14 offices throughout Australia and New Zealand, employing 1000 people.
Up to 100 people are expected to be involved during the design and build phases of the pump station, including sub-contractors. The pump station, according to the NT Government, is part of a $36 million multi-year project to increase pumping capacity and support water supply to the Darwin region.
The Darwin River Dam, now 50 years old, was constructed in 1972 and supplies 85% of the Darwin region’s water while the other 15% is sourced from the McMinns and Howard East borefields. The project has been designed to complement the Manton Dam Return to Service and Adelaide River Off-stream Water Storage projects.
Built in the 1940’s, the Manton Dam was Darwin’s primary water source prior to the Darwin River Dam’s construction and has been used for recreation since the 1980’s, but maintained for potential future water supply.
Power and Water will commence stakeholder engagement in the coming months to round out the environmental assessment referral process for the return to service project. The Manton Dam project will involve a refurbished intake tower, new pumping station and pipelines, and a new water treatment plant.

In non-contact annular labyrinth seals used in turbomachinery, the fluid pre-rotation in the direction of shaft rotation effectively increases the fluid velocity in the circumferential direction and could generate destabilizing fluid forces exerting on the rotor. Swirl brakes are typically employed to reduce the fluid pre-rotation at the inlet of the seal. The inlet flow separates as it follows the swirl brakes, and the ratio between the tangential component of the velocity in the seal and the velocity of the rotor surface varies consequently. Effective swirl brakes can significantly suppress the destabilizing fluid forces as it is effectively reduces the tangential velocity. In literature, it was shown that leakage rate can also be reduced by using swirl brakes with “negative-swirl”.
In this study, a labyrinth seal with inlet swirl brakes is selected as the baseline design and seal performance is evaluated using ANSYS-CFX. The design of experiments (DOE) approach is used to investigate the effects of various design variables on the seal performance. The design space consists of swirl brake’s length, width, curvature at the ends, the tilt angle, as well as the number of swirl brakes in the circumferential direction. Simple random DOE sampling method with Euclidean distances for the design matrix is used to generate the design points. The steady-state CFD simulations are then performed for each design point to analyze the performance of the swirl brakes. The quadratic polynomial fitting is used to evaluate the sensitivity of the average circumferential velocity with respect to the design variables, which gives a qualitative estimation for the performance of the swirl brakes. The results provide a better understanding of which design variables are critical and more effective in reduction of the destabilizing forces acting on the rotor, and thus will support the swirl brake design for annular pressure seals.

Bolangir: The Lower Suktel irrigation project, a dream project of the residents of Bolangir district, is finally taking shape with the construction of the project reaching its last leg. Works on the spillway and soil embankment of the dam are nearing completion while the gap in between is being filled up in war footing. The project when completed will help irrigate 40,000 hectare of farmland and supply 8.76 million cubic metre (MCM) of drinking water to the residents. According to available information, work on the project may get completed towards the end of June.
A plan has been made to store this year’s rainwater in the Suktel reservoir which will benefit over 1 lakh farmers. Construction of the dam and the irrigation project is being done simultaneously. The project will be the first in the state to have underground pipelines (UGPL) to run on electricity for irrigation purposes instead of constructing conventional canals. The UGPLs will help in irrigating larger tracts of land.
Over Rs 1,700 crore is being spent on the construction of the UGPL. The original Lower Suktel project had plans for the construction of an open canal which was expected to irrigate over 31,000 hectare of farmland in Losingha, Bolangir, Puintala blocks in the district and Tarabha block in neighbouring Subarnapur district. However, after authorities planned the construction of UGPLs instead of the open canal the area which will be irrigated by the project has increased to 40,000 hectare from the initially planned area of 31,000 hectare. It has now been planned that the left UGPL of the project will be used to irrigate 13,000 hectare of farmland in 65 villages and the right UGPL will be used to irrigate 27,000 hectare of farmland in 140 villages.
Meanwhile, construction of a pump house for the right UGPL has started at Khuntapali while for the left UGPL, a pump house is being constructed at Ranipali. Construction of the left UGPL and its pump house is being done by a consultancy firm ‘Megha company’ while the construction of the right UGPL and pump house is being done by L&T consultancy firm. The project will also provide drinking water facilities to Bolangir town and nearby villages.
Over 8.76 MCM of water will be supplied as drinking water which will benefit over 80,000 people. As the project work is nearing completion, people are thronging to the work site to get a glimpse of the mega irrigation project. Chief Construction Engineer of the project Sunil Rout said that the project work is in the final stage and efforts are on to finish other related works as soon as possible. He expressed confidence that very soon the project will be completed. When contacted, Bolangir Collector Chanchal Rana said that work on the project is at the final stage and very soon the project will be completed. He said providing irrigation facilities for the farmlands and supply of drinking water for the residents are the priorities of the project. He ruled out water supply to the industries and dismissed the talks in this regard as rumours and not based on facts. Water supply to the industries is also not mentioned in the detailed project report (DPR), he added.

Wild Rice River being rerouted through concrete structure
FARGO, N.D. (Valley News Live) - It’s a big day for the Fargo-Moorhead Diversion Project. The U.S. Army Corps of Engineers is rerouting the Wild Rice River through a gated concrete structure, which is a first for the project.
After three years of construction, Ames Construction, Inc., is permanently diverting the Wild Rice River. This reroute will allow Ames to complete construction of a dam embankment across the existing Wild Rice River channel.
The Wild Rice River Structure is a concrete control structure with two 40-foot wide Tainter gates. Upon completion of the entire diversion project, the Wild Rice and Red River structures will regulate flows through the metro area during large flood events. The Red River Structure is also under construction and the permanent reroute of the Red River through that structure is anticipated in the next two to three years.
“This year is another year we’re going to flood,” said Fargo Mayor Tim Mahoney. “When we’re finally done with the diversion we’ll be able to defend.”
The structures will not be used to control flooding until the entire diversion project is complete and approved for operation. Mahoney says in 2009, six million sandbags were made to protect the area from flooding. Because of flood mitigation measures, the city now prepares about 20,000 sandbags. He says with the completion of the F-M Diversion, sandbags will no longer be needed.
The Wild Rice River Structure is a part of the congressionally authorized Fargo-Moorhead diversion project which includes 30-mile-long diversion channel in North Dakota with upstream staging. The plan includes a 21-mile-long southern embankment, multiple highway and railroad bridges, three gated control structures and two aqueduct structures.

About the sleepers river
The Sleepers River is a 17-mile long river located in northern Vermont. Its headwaters are located in Greensboro and it flows south through Danville before joining the Passumpsic River. The river was historically used for logging and milling, but today it is mainly used for recreational purposes such as fishing, kayaking, and swimming. The river is also an important source of water for agriculture, with several farms located along its banks. The largest reservoir on the Sleepers River is the Joe's Pond Reservoir, which was created in 1848 to power a sawmill. Other smaller dams and reservoirs are located along the river for hydroelectric power generation. The Sleepers River is a significant tributary of the Passumpsic River, which eventually flows into the Connecticut River.

Simulation of Automatic Water Level Control System by Using Programmable Logic Controller IJTSRD
This research focuses on the design and implementation of a PLC based water level control system. In this research, there are three primary objectives the water level indicator circuit design, manual control system of water level control and the PLC based automatic water level control. Float switches cannot be able to use to indicate the multi water level in the desired control system. Therefore, AND gate based digital electronic water sensor is invented and used in this proposed not only manual water level control but also PLC based automatic water level control by dividing in eight steps. Induction motor is used to drive the pump as a one set package. So, induction motor starting method is selected according to the power rating of motor, type of motor and nature of application. Star delta starting method is used to reduce the starting current of induction motor. For PLC based automatic water level control, Siemens S7 1200 PLC is used to control the desire water level. There are 10 inputs and 10 outputs in the proposed automatic water level control. Ladder diagram programming is used for this control.

Working Principle of Hydraulic Screen Changer
Hydraulic screen changer can be divided into single plate double station hydraulic screen changer, single column double station hydraulic screen changer, double plate double station screen changer and double column double station screen changer.
The working principle of the single plate double station hydraulic screen changer: two detachable filter stations are designed on the slide plate of the single plate hydraulic screen changer. When working, one filter station filters the melt inside the main body, and the other one station is reserved outside the main body (there is a stainless steel heating rod on the slide plate for heating and heat preservation to ensure that the temperature is similar to the production temperature). When the impurities on the filter screen accumulate to a certain level during work, the screen needs to be changed, and the operating handle button on the hydraulic station can be pressed to start the energy storage hydraulic station to perform the screen change action.
The working principle of the double plate double station hydraulic screen changer: the two filters of the double-plate double-station screen changer work at the same time. When the screen needs to be changed, the hydraulic station can be started to change the screen. The screen works, one screen is replaced, two screens are exchanged to replace the screen, through the introduction and exhaust device, the air in the flow channel is exhausted to achieve non-stop screen replacement, no material leakage, no material flow interruption, and small fluctuations in material pressure. Small impact, good continuity of production requirements.


Tanzania’s long road to boost its electricity portfolio gained pace Wednesday after prime minister Kassim Majaliwa launched the construction of the main dam at the Rufiji river.
The dam is part of Julius Nyerere Hydropower Station planned to have a capacity of 2,115 megawatts and produce 6,307 GWh per annum. The capacity of the dam’s reservoir is 34 billion cubic meters.
Also known as Rufiji Hydroelectric Power Station, the project has also involved diversion of Rufiji water to allow construction of the electric dam.

Tanzania has been considering to establish the power station since the 1960s. When fully developed, it will be the largest power station in East Africa. The 134 metres (440 ft) arched, concrete dam is expected to create a reservoir lake, 100 kilometres (62 mi), in length, measuring 1,200 square kilometres (460 sq mi), with 34,000,000,000 cubic metres (1.2×1012 cu ft) of water.
in 2017, The government of Tanzania handed over the construction site to the consortium comprising Arab Contractors and El Sewedy, both of Egypt, who had been selected to build the power station.
In April 2019, the Tanzanian government made an upfront payment of US$309.645 million, representing approximately 15 percent total cost of construction. As of June 2020, the project is 40 percent complete.
Construction of the hydroelectric project is set for .2022. If successfully completed Julius Nyerere Hydropower Station would be Africa’s largest dam by installed capacity, over Egypt’s Aswan High Dam (2100 megawatts) Mozambique’s Cahora Bassa Dam (2075 megawatts) and Angola’s Lauca Dam (2069 megawatts).
At 2,115 megawatts, the dam’s contribution is more than the current peak demand of Tanzania. The country’s highest recorded power demand was 1051.27 megawatts in February 2017.
Installed capacity has been reported to be between 1366.60 megawatts and 1,602 megawatts. The Stiegler’s Gorge Hydropower Project will therefore significantly increase the installed capacity on-grid in Tanzania, supporting power for industrialisation and electrification.
But the project has also received criticism from environmental experts because the location of the gorge is in the middle of the Selous Game Reserve World Heritage Site. Conservationists are opposed to this project saying it threatens the endangered animal species in the area especially the black rhinoceros and elephants.


South Africa's Clanwilliam Dam Project Completion Extended
The dam rehabilitation project is now expected to be completed in February 2028.
South African Minister of Water and Sanitation, Senzo Mchunu, has announced an extension to the completion date of the Clanwilliam Dam project. Responding to a question in Parliament, Mr. Mchunu said work on the project had ground to a halt, but is expected to resume in early 2023.
The delay is reported to have increased project costs by R676m (US$37.1 million).
The Clanwilliam dam is located at the foot of the Cederberg Mountains in South Africa’s Western Cape. The dam was originally constructed in 1935 and raised to its present height of 34 metres in 1964.
The dam is currently undergoing remedial works to raise the existing dam wall by 13 metres and improve the foundation of the dam. This follows studies which showed that the dam's sandstone foundation is fractured, with the concrete deteriorating. Solutions considered include the introduction of anchors on the existing concrete apron and deeper foundations to suitable bedrock.
The dam rehabilitation project began in 2013.
The raising of the dam wall is expected to increase the yield of the dam yield by 70 million cubic metres per annum to boost the water supply to the Olifants River irrigation scheme in the northwestern part of the Western Cape Province. This will be a crucial aid to local farmers in the catchment area.
Mr. Mchunu said the department of of Water and Sanitation had established an infrastructure procurement office to initiate a recovery plan for the project. “It is envisaged that this will allow the department to expedite the processing of tenders for procurement of construction materials so that construction activities can be resumed by February 2023," said the Minister.
To help the project progress further, the Department of Water and Sanitation established an infrastructure procurement office to initiate a recovery plan for the project. "It is envisaged that this will allow the department to expedite the processing of tenders for procurement of construction materials so that construction activities can be resumed by February 2023," said Mr. Mchunu, Minister of Water and Sanitation.
On completion of the raising of the Clanwilliam dam wall, a second phase of the project will involve efficient utilization of the additionally yielded water by supplying ecological water requirements, giving existing water users a more stable water supply and using the additional water for new irrigation activities by emerging farmers.
The Clanwilliam Dam project is part of a wider network of projects called the Olifants Doorn River Water Resources Project (ODRWRP). The ODRWRP also involved the realignment of the N7 national route, which was completed successfully by SANRAL in 2017.
The ODRWRP further includes upgrading and expanding the conveyance network downstream of Bulshoek Dam by the DWS. The scope of the project also includes site establishment, access roads, support infrastructure / upgrades to the N7, land acquisition, design administration, and project communication. On completion, the project will help stabilize water resources infrastructure, help create jobs and provide for future accommodation of a hydro-power plant. This will help in enhancing green development projects in the country.

The original concrete weir built in 1976 was meant to be used as a drinking water reservoir with a capacity of 9 million m³. In 1995 the storage capacity was extended by 3 million m³ through the addition of rubber dams. These rubber dams were modernized and updated to the state of the art by Floecksmühle in 2013. The weir was divided into two spans and a new control system was installed.
During the dry season the weir is completely deflated. The weir is fully inflated only during the rainy season so the maximum reservoir capacity is available.
