The Sardar Sarovar Project is one of the largest water resources project of India covering four major states - Maharashtra, Madhya Pradesh, Gujarat and Rajasthan. Dam's spillway discharging capacity (30.7 lakhs cusecs) would be third highest in the world.
With 1133 cumecs (40000 cusecs) capacity at the head regulator, and 532 km. length, the Narmada Main Canal would be the largest irrigation canal in the world.
The dam will be the third highest concrete dam (163 meters) in India, the first two being Bhakra (226 metres) in Himachal Pradesh and Lakhwar (192 meters) in Uttarakhand.In terms of the volume of concrete involved for gravity dams, this dam will be ranking as the second largest in the world with an aggregate volume of 6.82 million cu.m. The first is Grand Coule Dam in USA with a total volume of 8.0 million cu.m. This dam with its spillway discharging capacity of 85,000 cumecs (30 lakh cusec), will be the third in the world, Gazenba (1.13 lac cumecs) in China and Tucurri (1.0 lac cumecs) in Brazil being the first two.
The reservoir would occupy an area of 37,000 ha. and would have a linear stretch of 214 kilometer of water and an average width of 1.77 kilometer. The Full Reservoir Level (FRL) of the Sardar Sarovar Dam is fixed at RL 138.68 metres (455 feet). The Maximum Water Level is 140.21 metres (460 feet.) while minimum draw down level is 110.64 metres (363 feet.). The normal tail water level is 25.91 metres (85 feet.).


Nigeria currently has a capacity to generate close to 5,000 MW of electricity but hardly maintains 4,000 MW. The federal government is working to ensure that the construction of the following power plants will be completed this year:
Kashimbila Hydropower (40MW)
Gurara Hydropower (30MW)
Kaduna Power Plant (215MW)
Unsteady supply of gas to power plants due to pipe vandalization is the main culprit for this setback. Power Minister, Babatunde Fashola announced last year that FG is working to build hydropower plants to forestall this problem.

Reconstruction of the Measuring and Test Equipment (MTE) for the Maina Hydraulic Power System
Bancomzvjazok’s specialists have performed the analysis of the initial data and developed the design documentation for automation of the measuring and test equipment of the Maina Hydraulic Power System (Russia) as part of a joint project with Lenhydroproject, JSC—“The Integrated Reconstruction of the Maina Hydraulic Power System” in the shortest time. Our project includes key issues on MTE automation of earth dams and concrete structures. The customer of the project—Lenhydroproject, JSC—is one of the largest design and survey institutes in Russia, occupies one of the leading positions in the field of design of hydroelectric and water management facilities and performs a full range of design and author supervision services for the construction of hydraulic structures in areas with particularly complex geological-climatic conditions. The Maina Hydraulic Power System, located in the south of the Republic of Khakassia, in the head of the Yenisei River, was built at the end of the last century. The Sayano-Shushenskaya Dam and Maina Hydraulic Power System is a single hydropower complex. Its main purpose is to smooth fluctuations in the river level in tail water, create satisfactory conditions for water users, and generate additional electricity. The Maina Hydraulic Power System includes the right bank, channel, and left-bank earth dams, a HEP building with three hydraulic units with rotary-bladed turbines, and a concrete spillway dam with five spans of 25m each. The installed capacity of the Maina HEP is 321 thousand kW; the annual power generation is 1.7 billion kWh. The designed measuring and test equipment takes into account a wide range of factors affecting the reliability and safety of the Maina HEP facilities. In order to automate and increase the promptness of the collection of readings, the measuring devices existing at the station will be equipped with automatic sensors. According to the project, the hydraulic levels will be equipped with a geodetic micrometer altimeter in order to control the vertical movement of reinforced concrete blocks of structures, piezometers on earth structures—with pressure sensors to control the depression curve. It is planned to equip the head of the water structures with pressure sensors and a string of thermometers to measure the water level and control the filtration horizons through concrete structures. Multiplexers and local data concentrators installed will perform interrogations of collateral equipment, automation sensors and further transfer of measurements to the central processing unit. In addition, Bancomzvjazok JSC was faced with the task of designing the head of a piezometer located under the roadway along the dam crest. The difficulty was that this device should be used in an unusual and uncharacteristic area. The company's specialists have developed and proposed a unique design of the head of a piezometer that will allow taking large point loads without damaging it. For each site, the type of the cable routes laying and the location of secondary equipment have been considered.

Responsible authority needs to pay attention to debris which has been accumulating in Umzingwane River since the onset of the rain season.
The river is a major left-bank tributary of the Limpopo River in the country.
It rises near Fort Usher, Matobo District, south of Bulawayo and flows into the Limpopo River near Beitbridge, downstream of the mouth of the Shashe River and upstream of the mouth of the Bubye River.
The Mzingwane River is an ephemeral river with flow generally restricted to the months when rain takes place (November to March), with most flow recorded between December and February, except where it has been modified by dam operations.
The river contributes 9.3% of the mean annual runoff of the Limpopo Basin, making it the third largest tributary to the Limpopo basin.
Major tributaries of the Mzingwane River include the Insiza, Inyankuni, Ncema, Umchabezi (not to be confused with Mtshabezi) and Mtetengwe Rivers.
The lower Mzingwane River is a sand filled channel, with extensive alluvial aquifers in the river channel and below the alluvial plains.
Currently, some of these aquifers are being used to provide water for domestic use, livestock watering and dip tanks, commercial irrigation and market gardening

Taipan to invest over $700 million in hydro power plants
By Donnabelle L. Gatdula Updated February 23, 2009 12:00 AM
MANILA, Philippines – One of the country’s taipans is planning to invest over $700 million to put up hydro power facilities in Luzon and Mindanao, well-placed industry sources said.
“A group of investors, including a taipan, is putting up hydro power plants in several locations in Luzon and Mindanao,” the sources said yesterday.
They said the consortium is now in the process of conducting land surveys in preparation for the construction of a 332-megawatt (MW) hydro power facility in Luzon.
This capacity, the sources said, could be expanded up to another 300 MW.
According to sources, the taipan really wants to take an active role in the government’s effort to develop renewable energy (RE) sources.
“Hydro power is clean and renewable,” the sources said, when asked why the taipan chose to build a hydro power facility.
There are over 40 indicative hydro power projects that are listed in the Department of Energy’s Philippine Energy Plan (PEP) which will generate 1,025 MW.
The Metro Luzon Urban Beltway and Mindanao regions host the bulk of the potential projects with a total capacity of 368 MW and 369.8 MW, respectively.
The biggest indicative project based on the PEP is the 360 MW expansion of CBK Power of the Kalayaan Pumped Power Storage in Laguna which is expected to be completed in 2011.
Another huge hydro power project expected to be completed in 2011 is the Salug Daku hydro power plant in Saguiaran, Lanao del Norte.
The PEP indicated that there are already 14 hydro power projects with feasibility studies all over the country. These projects are estimated to provide an additional 255.2 MW to the country’s hydro power capacity.
The projects are being undertaken by various developers. These are: Solutions Using Renewable Energy (SURE); Province of Biliran; PNOC-EDC/Soluziona, Chase Makros Management Inc. (CMMI); Benguet Power Resources Development Corp.’ First Gen Visayas Hydro Power Corp.; and the Sta. Clara Power Corp.
The DOE noted that two of these projects will proceed to the construction phase. These are: Colasi in Mercedez, Camarines Norte; and Sipangpang in Cantilan, Surigao del Sur projects with a potential capacity of 1 MW each. Both projects are expected to be completed this year.

Lateral intake is a structure constructed next to a main channel to divert part of the flow within the channel. The separated area of the flow in the entrance of intake channel has no effect on flow discharge while reduces the effective cross-sectional area of the intake, as well as the bed load, which enters the intake due to low velocity flow deposits in this area. Thus, knowing the dimensions of the separated area at the intake channel entrance is particularly important. In this study, flow separation zone was calculated at the intake entrance of 90 degree in three depths of 3, 6, and 12 cm from the bottom of the channel for discharge ratios of 0.2 and 0.4, 0.6 and 0.8 in five turbulence models using three-dimensional Flow-3D model. In order to determine the accuracy of the model in predicting the dimensions of the separated areas, the obtained results were compared with the results of the physical model. Streamlines were drawn and dimensions of the separated areas were determined. In comparing results between the laboratory observations and the predicted ones by numerical model, Reynolds Normal Group model (RNG) had better predictions, with a correlation coefficient of 0.97, root mean square error of 3.16, and a mean absolute error of 2.3 cm, than other turbulence models.

Like the singular inclined plane at Georgetown, at Mile 174.2 are the remnants of the only steam pumping station along the canal. The original steam pumping station was constructed in Oldtown and used for about 20 years. It was inefficient and aging, so a new steam pumping station was built here in 1872. The steam pumping station pumped water up from the Potomac and directly into the canal ditch. As Dam Number 7 was never built and Dam 8 at Cumberland had to water the canal for 50 miles, canal engineers thought this would help keep canal levels deep enough for boats to safely pass through the canal's waters.

Mtera Dam – Overview, Ecology, Project Phases and More
Mtera dam is a hydropower dam in Tanzania. This dam is situated midway between Dodoma and Iringa on the boundary between Dodoma and Iringa regions. It takes two hours to reach the dam from Dodoma when travelling on a tarmac road.
Overview of the Mtera Dam Tanzania
Mtera Dam is a big hydropower dam located in Tanzania. At full capacity, The dam measures 250 square miles (660 sq km). The lake is 9.3 mi (15 km) wide and 35 mi (56 km) long and is fed by River Kisigo and the Great Ruaha River. It was constructed between 1975 and 1979 to regulate water level downstream at the Ruaha installed Kidatu Hydropower Dam. Its total capacity is 110,000 horsepower (80 M.W.).
The lake is regarded as one of the best Tanzania birding tours location because there are many shallow areas and close to 1 million dead trees. Also, the waters have a rich population of fish. During the early 1990s, close to 5,000 tonnes of fish were caught in the lake.
Phase I (1970 to 1975)
The first phase of the Mtera Dam project involved building a 350 m long and 40 m high earth rockfill dam and an underground power generation plant at Kidatu. Two generating sets, each with a capacity of 50 M.W., were installed at the power plant for a total capacity of 100 MW. The rockfill dam, situated around 10 km upstream of the underground power plant, provided the plant with a regulation reservoir with a total storage capacity of 125 million cubic metres and an unlined headrace intake tunnel of 9.6 km long down to the power plant.
Phase II (1977 to 1981)
The second phase of the project involved the additional installation of two units of 50 M.W. generators at the Kidatu Hydro plant. The installation brought the plant’s total capacity to 200 MW. It was, however, realized that the Kidatu Reservoir volume was not big enough for yearly regulation and continuous use of the four generating sets. To handle the availability of water during the dry season of normal years and a series of dry years, optimal storage had to be put in place upstream of Kidatu. The idea of constructing a primary storage dam at Mtera around 170 km upstream of Kidatu was conceived for this reason.
Phase III (1984 to 1988)
The third phase of the Mtera Dam project involved the building of an underground power plant at Mtera. Two units of 40 M.W. generators totaling 80 M.W. were installed. There is a water intake for a short headrace tunnel close to the dam as well as penstocks to the power house before the water is discharged through a long tailrace tunnel.
The Mtera Dam and Power Station
- The Mtera Dam is a buttress-type concrete structure with its crest level at 701.5 m above sea level. The dam’s main tributaries are the Kisigo, Little Ruaha, and Great Ruaha Rivers. The dam was completed in December 1980 and was commissioned by late President Julius Nyerere on February 19, 1981.
- The dam is the largest in Tanzania in terms of concrete volume, crest length, and height. The dam’s impounded reservoir is also the largest artificial lake in the country. It is also the road bridge between the Dodoma and Iringa regions and part of the Great North Road (Cape Town – Cairo)
- The hydroelectric plant has an installed capacity of 80 megawatts. Power generation began on May 22, 1988, for unit 1 and December 7, 1988, for unit 2.

Intermittent road restrictions continue as hydro project progresses
The mild weather this week has allowed crews at the Red Rock Dam to continue working day and night to prepare the site for construction of a powerhouse and intake structure that will comprise the Red Rock Hydroelectric Project (RRHP). Short-term road closures, directed by the Marion County Sheriff’s Department, will occur in the overnight hours every three to four days as crews move large rebar cages from the North Tailwater staging area to the construction area on the upstream side of the Dam. In addition, Highway T-15 will be restricted to one lane every three to four days to facilitate staging of the concrete trucks to ensure worker and public safety as the wall element sections are poured.
Downstream work prepares for RRHP powerhouse construction
Construction continues at the Red Rock Dam where Missouri River Energy Services (MRES) will construct a new hydroelectric power plant. Much of the construction work being done is in preparation for construction of the powerhouse, which is expected to begin in summer 2015.
On the downstream side of the Red Rock Dam, the construction of the cofferdam, which is located between the Des Moines River and the power plant site, is well underway. The construction of Cells #1 and #2 are largely complete, Cell #3 is being filled with sand, and the walls of Cell #4 are being installed.

The Governments of Tanzania, Rwanda and Burundi have commissioned works for the construction of 80MW Rusumo power dam on River Kagera. Once completed, it is expected that the three East African countries will equally distribute the power output; each connecting about 30MW to its national grid.
In November last year the trio announced that two Chinese companies- China Geo-Engineering Corporation, Jianxi Water and Hydro Construction Ltd and Austria’s Andritz Hydro had been selected for the civil, electronic and mechanical works on the power plant. The works are expected to be completed by 2019.
The dam project is funded by the World Bank and the African Development Bank to the cost of US$340million. The works include construction of the power plant. It also includes construction of 161 km of 220 KV, single circuit transmission line from the power plant to Gitegavia Muyinga substation in Burundi; 119 km of a 220 KV, double circuit transmission line system from Birembo substation through the new Bugesera International Airport substation in Rwanda and a 98.2 km, 220 kV, double circuit transmission line system, from the power plant to the new Nyakanazi substation in Tanzania.
The dam will be run by the Rusumo Power Company Ltd (RPCL), a limited company, publicly owned and financed by the three countries but privately managed.


Built in 1956, Hirakud Dam in Odisha is the world’s longest earthen dam and Asia’s largest artificial lake. It is also one of the largest dams in the world, about 26 kilometers in length.
Hirakud Dam is built across the Mahanadi River, about 15 km from Sambalpur in the state of Odisha in India. Behind the dam extends a lake, Hirakud Reservoir, 55 km long. It is one of the first major multipurpose river valley projects started after India’s independence.
On 15 March 1946, Sir Howthrone Lewis, then the Governor of Orissa, laid the foundation stone of the Hirakud Dam. The dam was completed in 1953 and was formally inaugurated by Prime Minister Jawaharlal Nehru on 13 January 1957. The total cost of the project was Rs 100.02 crores (in 1957).
The main purpose of the Hirakud Dam was to check the massive floods that were affecting a large part of coastal Odisha. But, the construction of the dam greatly affected the natives of the western part of Odisha. Nearly 150,000 people were affected by the Hirakud project and nearly 22,000 families were displaced.

Gas-lift pumps are devices for lifting liquid phase incorporating the gas phase to be injected in the bottom of liquid column. They are widely used in various industrial applications such as oil extracting in petroleum industries. Gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, churn and annular. Considering each numerical method to be appropriate for modeling a certain flow regime, a suitable numerical approach is crucial to correct simulation of gas-liquid flow in upriser pipe of gas-lift systems. In this paper, two main approaches namely the volume of fluid (VOF) and Eulerian model are used for modeling of the two phase flow in the upriser pipe of the airlift system. The numerical results are compared with the experimental investigations to validate the numerical models. The two phase flow regimes simulated by the numerical method were compared with the available flow regime map in the literatures. The results indicate that using the VOF is more appropriate for modeling of bubbly and slug flows while the Eulerian model fits better for only annular flow regime.

Chisang Khola A Small Hydropower Project
Proposed Chisang Khola A Small Hydropower Project, located in Morang district of Koshi Zone, is a run-of-river type project. The project has been designed to generate 1800 kW power using water from Chisang Khola.
The project site is accessible by about 12 km of fair-weather motorable road from Letang Bazaar to Pitlumba nearby headworks site. About 2 km of access road construction is necessary to connect headworks site from Pitlumba. About 3 km alignment is proposed from headworks to powerhouse which again needs access road. The access road to the construction site is ready.
The annual energy generation capacity of the project is 10.32 GWh. The power generated from this project will be connected to the National grid near the Letang bazaar. The length of proposed transmission line is about 5000m.
The project alignment passes mostly through stable cultivated terraces except at a very short reaches where the alignment passes through steep rock slopes. The alignment provides suitable geological conditions and at the same time nullifies the necessity of felling down of trees. The project needs to occupy about 5 Ropani of private land in total & it is done already.
The design discharge for the proposed project is taken as 1.37m3/s. The gross head is 170m and the net head under full flow conditions is 153.23 m. The project will run on its full capacity for about five months.
Conveyance of water from intake up to the desalting basin will be through a connecting canal of size 1.5m wide and 1m deep with 125m length. After the descanting basin, headrace pipe of 0.80m diameter and 2760m length will convey the design discharge towards the Forebay. Finally steel penstock pipe of 190mm diameter and thickness varying from 8 to 10 mm shall convey water up to the proposed powerhouse.
Two units of Pelton turbine, each of 900 kW capacities, shall be installed inside the powerhouse. The plants will generate 1800 kW power during full flow conditions. Net energy generation from this project will be 10.32 million units per annum.
The energy generated from this project shall be sold to Nepal Electricity Authority (NEA). The price of energy is kept at NRs. 8.40 for the dry months (Poush-Chaitra) and NRs. 4.80 for remaining months which are considered as wet months, based on the NEA's rates for buying electricity from independent power producers for the fiscal year 2060/61. The annual increment of the price afterwards will be revised based on the consumer price index of Nepal Rastra Bank.
The project will minimize cutting soil, rocks and plants during the construction period. The project will plant trees to maintain greenery in the project site.
The construction period of the project has been kept at 24 months from the date of (PPA) made with the Nepal Electricity Authority (NEA).


The project comprised the replacement of the existing cast iron rainwater pipework with handmade cast iron replicating the original design and fixing methods. The thirty-six rainwater pipes were accessed from specially designed scaffolding which had to be erected without intervention of the existing façade of the cathedral.
Each of the windows to the cathedral was carefully protected to prevent possible damage from the works. The stonework adjacent to the rainwater goods was conserved and repaired prior to the new pipework being installed. Additional underground drainage was installed to assist the water discharge.

What we're doing
About the Waipaoa River flood protection scheme.
The Waipaoa River Flood Control Scheme (the scheme) was designed in 1949 and was completed in 1969. It was valued by Council in 2009 at $35.7 million which excluded the 638 hectares of land owned by Council as part of the scheme.
The scheme is considered to be one of Council’s most valuable assets. It protects some 10,000 hectares of fertile floodplain land and has increased the amount of land being used for high yield horticultural purposes.
The scheme includes 64km of stopbank and associated assets which is the length of the Waipaoa River between the Te Karaka township and the rivermouth.
The project will improve the capacity of the existing scheme and:
♦ Address riverbank erosion. This will be through either providing rock protection or acquiring land in order to widen the existing river berm.
♦ Increase the width of the existing stopbanks to have a 4m crest-width and increase the crest height by around one metre.
♦ Maintain flood protection for a one-in-100-year flood event accounting for climate change out to the year 2090.
Currently the project is forecast to occur over a 15-year period at a cost of $16 million.
The first stage of the project is set to commence construction in summer 2018/2019.
Currently, the annual construction length is 5-8km, with construction occurring only over the summer months.

Accurate river level predictions using a Wavenet-like model (Papers Track)
Shannon Doyle (UvA); Anastasia Borovykh (Imperial College London)
The effects of climate change on river levels are noticeable through a higher occurrence of floods with disastrous social and economic impacts. As such, river level forecasting is essential in flood mitigation, infrastructure management and secure shipping. Historical records of river levels and influencing factors such as rainfall or soil conditions are used for predicting future river levels. The current state-of-the-art time-series prediction model is the LSTM network, a recurrent neural network. In this work we study the efficiency of convolutional models, and specifically the WaveNet model in forecasting one-day ahead river levels. We show that the additional benefit of the WaveNet model is the computational ease with which other input features can be included in the predictions of river stage and river flow. The conditional WaveNet models outperformed conditional LSTM models for river level prediction by capturing short-term, non-linear dependencies between input data. Furthermore, the Wavenet model offers a faster computation time, stable results and more possibilities for fine-tuning.


Updates of the construction of a new resorvoir worth 200.000litres
The Bamenda III Council is currently carrying out the construction of the second Giant water Reservoir with a capacity of worth 200m3 (200,000Litres) added to the former with a production capacity of 80m3(80,000litres).This added reservoir will contribute greatly in optimizing the production capacity of the water Purification plant.
The second reservoir will be of great importance to the council and the community at large because it will serve as a storage tank especially in bad weathers where filtration cannot be done as well as sustain network and reduce shortages. Furthermore, with a construction of a basement plant through which a water pump is established, quarters with difficulties to access water due to their location altitude and a steady supply of water.
With the constrution of a site house and fenced wall,security is well assured


Hydro plants boost Nigeria’s power generation to 3,686.3mw
Nigeria has managed to attain electricity generation and supply of 3,686.3MW after several months of blackout occasioned by cuts in gas supply to power plants largely as a result of high water levels at the nation’s dams, which enabled the three hydro power plants namely, Jebba (360mw), Shiroro (600mw) and Kainji (440mw) to operate at optimal capacity, The Guardian reports.
Data from the current daily operational report of the Transmission Company of Nigeria (TCN) for yesterday, showed that Kainji Hydro with 440mw installed capacity is currently generating 305mw, Jebba with installed capacity of 360mw is working at full capacity while Shiroro with installed capacity of 600mw is generating about 560mw.
Other power plants, which have also contributed significantly to the rise in electricity, include Egbin Steam, with installed capacity of 880mw, which is contributing 407mw. Sapele is also generating at full capacity. This, is notwithstanding the country’s unutilised power generation due to gas constraints which stood at 4,517mw, as at yesterday.

Tripartite negotiations on Ethiopia’s Nile River dam continue without progress toward an agreement. The talks follow a UN Security Council meeting last week on Ethiopia’s planned filling of the dam and opposition from Egypt and Sudan.
Ethiopia wants to fill the massive Grand Ethiopian Renaissance Dam (GERD) this month. The dam is on the Blue Nile River, which flows into the Nile. Ethiopia wants the project to supply the country with hydroelectric power and help alleviate poverty, while Egypt and Sudan believe that filling the dam will deplete water levels in the Nile in their countries. The river is a major part of east African economies.

This project would provide for the construction of a 10-foot by 10-foot reinforced box culvert for a distance of approximately 270 feet adjacent to the residences. In addition to the 270 feet of box culvert, mitigation of the channel is necessary at the upstream end and downstream end of the box culvert in order to provide a transition from open flow to the culvert and from the culvert discharge to the open channel. Additional stabilization is required in a secondary area of the channel to stabilize the toe of the channel and to prevent horizontal migration of the channel.
Project Status Update - 11/28/2016
A small portion of Oakwood Drive from Hickory Lane to 64th Street will be closed starting October 3rd, and will be closed until the project is shut down for the winter. Clearing of trees is completed and the box culvert construction is over half way completed. Rip-rap placement along the creek also nearly complete. The current schedule is to get the culvert completed this fall and the project will be substantially complete by mid-March 2017.
