Contract for the dam structure LOT A2 for HPP Brežice signed
Bogdan Barbič (CEO HESS) and Miljenko Muha (Chairman of the Board at Kostak d.d.) signed a contract for main construction works on the HPP Brežice dam structure. The contract was signed at Podsreda Castle.
HPP Brežice is the fourth in the chain of hydro plants on the Lower Sava River; fully constructed and operational are HPP Boštanj, HPP Arto-Blanca and HPP Krško. The HPP construction is divided into several parts, determined by tenders. Preparatory work at HPP Brežice began on 25 March 2014. A bypass channel through which the Sava has been rerouted, digging works are still underway, as well as pumping water and sealing the flood barriers in the construction pit.
Some important data about the dam structure – the topic of the contract.
The subject of the contract is the provision of main construction works for the dam structure, which consists of reservoir pools, the machine facility and its extension, wall on the wings of the facility, as well as the ramps for pouring-in and –out. Works on the electric and machine installation will be carried out, as well as construction works on multipurpose storage facility and on barrier seals in the construction pit, and both banks of the Sava shall be fixed. The contract also determines an access bridge to be constructed over the Struga creek to reach HPP Brežice.
Tender documentation and the process of procurement according to the valid law were managed by HSE Invest d.o.o. on behalf of HESS d.o.o. The value of the transformers is set to 19,427,670.06 EUR, which represents approximately 17% of the value of constructing the production section of HPP Brežice. The works on the dam structure will take place from November 2014 to July 2017.
The construction works on the dam structure of HPP Brežice will be undertaken by Kostak d.d. – the main consortium partner – RGP d.o.o., CGP, d.d. and Kolektor Koling d.o.o. as consortium partners. All partners of the consortium are convinced that the works at the construction of HPP Brežice carry significant importance for the future development of personnel and expertise. In addition, one of the biggest investments in this country carries on – which is the most important.
The HESS company has already signed the contracts for turbine and generator equipment, bridge elevators and hydro mechanic equipment, soon the contract for the power transformer will be signed, as well. The contract for main construction works on the HPP Brežice dam structure is thus the last of the larger contracts needed to build the production section of HPP Brežice.

(Ecofin Agency) - The Gibe III hydropower dam in Ethiopia will be commissioned this Saturday, Dec. 17.
The 1870 MW infrastructure which has 10 turbines, generating 187 MW each, was developed by Italian Salini Impregilo. Construction took nine years and produced a 243m-long dam with a reservoir of 15 billion cubic meters. It cost €1.5 billion of which the Ethiopian government provided 40% while remaining 60% came from Exim Bank China.
Azeb Asnake, executive director of Ethiopian Electric Power said the plant would not be at full throttle once online due to the water level in its reservoirs. Truly, the dam currently generates 900 MW, but this output should increase gradually.
With Gibe III coming online, Ethiopia’s total production capacity now stands at 4200 MW. Power produced at the dam will help reduce the power deficit induced by the El Nino weather phenomenom.


High performance at a reasonable cost.
We design and realise preassembled pumping groups for every winery.
Our plants use high efficiency pumps with inverter, in order to obtain the lowest power consumption. Collectors and intercepting and control accessories are designed to reduce load losses and to assure the right flow rate at the project pressure.
Our pumping stations are sheltered in order to place them outside without further protections.
We produce stations for warm fluid distribution, with boilers, electric board and safety accessories.


Mongla Port Dredging Programme To Start In September

The dredging project is expected to be completed by November 2014.


In 1990 a series of seven dams was started in the Goksu River basin in southeastern Turkey. The goal of the dams was to provide long-term hydroelectric power to the region. Landsat satellite data have been used by government officials and by others to study the growth and impact of the dams as the Goksu River is one of the few remaining free flowing rivers in Turkey and the presence of the dams has impacted the aquatic species and wildlife in the area.
The Gezende dam was completed in the early 1990's. The diminished downstream flow of the river significantly affected aquatic species.
The construction, in the early 2000's of the Ermenek dam project created a large reservoir that inundated previous fragile wildlife habitat.

The unprecedented dry fall weather is forcing BC Hydro to implement another flow reduction on the Campbell River today (Tuesday, Nov. 29).
“We did a reconnaissance of the Campbell River riverbed and the current flows, and believe we can reduce the flow from 65 cubic metres per second (m3/s) to 55 m3/s without impacting salmon eggs in the gravel,” BC Hydro spokesperson Stephen Watson said in a Nov. 28 system update.
“While water levels remain extremely low on the Campbell River system along with other Vancouver Island hydroelectric watersheds, we are fortunate to have an integrated provincial system and the supply of power is not an issue.” Watson says. “Our large hydroelectric systems are in good shape.”
The snowpack in the upper watershed is less than 25 per cent of normal for this time of year, though the main snow accumulation months are December through March.
Like any precipitation, the Nov. 29 snowstorm is hlepful, particularly with low snowpakc levels. However, the cold temperatures will largely lock up that moistoure so the run-off into the reservoir will be quite low this week, Watson says.
“We need multiple larger storm systems, tropical-based systems, so we can get some good run-off into the reservoirs and, hopefully, get back to normal,” Watson says.
The forecasted water inflows into the watershed for this week are around 25 m3/s. The Campbell River system continues to lose available water storage. The Upper Campbell Reservoir/Buttle Lake is currently at 213.4 metres above sea level and slowly rising as we rebalance the reservoirs.
“Our investigative dam safety work at the Strathcona Dam spillway area was completed and since Friday we have been rebalancing this reservoir and the Lower Campbell Reservoir/McIvor Lake,” Watson says. “There is very little flow moving below the Strathcona Dam while the downstream Campbell River flow requirements are essentially being met from Lower Campbell Reservoir – this reservoir will continue to lower by another metre or so to about 175 metres. Both reservoirs may be aligned in another week or so.”

The Upper Campbell Reservoir provides about 80 per cent of the system water storage. Our licenced minimum reservoir level is 212 metres. With little combined reservoir storage available and very low inflows forecasted in the near term, a river flow reduction is required to conserve water should inflows remain lower than normal in the longer term.
The overall system reservoir water storage is the lowest on record for this time of year going back to 1984, and the Campbell River flow release will be the lowest since 1993.

What We Do
Anacostia River Tunnel Project
The Anacostia River Tunnels project is designed to capture and provide storage for combined sewer overflows (CSOs) being discharged to the Anacostia River. The project consists of a system of deep large diameter underground storage tunnels and associated diversion and pumping facilities. The tunnel system is for the conveyance and storage of combined sewage overflow and consists of a series of three tunnels from Blue Plains Advanced Wastewater Treatment Plant to the north east boundary area in the vicinity of Brentwood Reservoir. In addition, a system of smaller diameter branch tunnels will extend from the Brentwood site to locations along Rhode Island Avenue, for flood control.
When completed, this project together with CSO control projects already completed or underway are expected to reduce CSOs to the Anacostia River by about 98 percent.
The Anacostia River Tunnels are the first piece of the Clean Rivers Project to begin construction. Please continue to visit this page to learn about project updates.

Truckee Storage Project
The primary features of the Humboldt Project developed by Reclamation are the Rye Patch Dam and Reservoir, and the Battle Mountain Water Development and Collection System. Rye Patch Dam was completed in 1936 to provide supplemental and carryover storage for use on the Pershing County Water Conservation District irrigated lands. The Humboldt River flows are extremely variable and carryover storage is essential for the 30,000 acres of irrigated lands located near Lovelock, Nevada.
|Facility: Boca Dam and Reservoir - Boca Dam and Reservoir are located on the Little Truckee River about 27 miles southwest of Reno, Nevada.|


In 2015 the Region of Waterloo (RMOW) required assistance for design and construction services for the implementation of an alternative reservoir fill piping arrangement at the St. Jacobs booster pumping station and reservoir facility. The facility boosts pressures for the supply of water to St. Jacobs and Elmira from the Waterloo pressure zone. The original reservoir fill line, installed in the 1990s, conveyed water to the reservoir through a globe style control valve. Due to the existing piping arrangement maintenance of the valve (and replacement) required a complete shutdown of flows into the reservoir.
The design team decided that the
addition of a new reservoir fill by-pass line, and replacement of the exiting
line would be required to enhance the reliability of the station. C3W provided
project management, process design, construction services, and structural
design, while Cole Engineering provided electrical, instrumentation
& control, and SCADA design services.
High level tasks included as part of the scope were:
- Preliminary assessment of design alternatives on site with RMOW staff and identification of the preferred alternative
- Preliminary design of new process piping layout and hydraulic design for a new 200 mm and 250 mm reservoir fill line taking into consideration current and future demands, as well as current measured flows at the facility
- Detailed design of process piping, control, electrical, and pipe supports/thrust restraints for the new reservoir fill lines which included back pressure sustaining valves and butterfly valves for isolation
- Preparation of a detailed preliminary transition plan to provide guidance for required shut-down, construction phasing, commissioning, and disinfection activities required throughout
- Water modeling to assess and confirm the allowable duration of planned
shut downsrequired throughout transitionto the new piping arrangement. Modellingalso demonstrated that the supply for St. Jacobs was feasible without pumping, resulting in significant operational savings
- Pre-tender and tender period services including generation of tender package, bidders meeting presentation, and answering of contractor questions through
- Construction period services including contract administration, site inspection, and commissioning support.

I am new to fluent. I am going to model wind effect on water surface in a open channel flow.I am using VOF model and pressure inlet outlet for water, I don't know which kind of boundary condition should be used for wind.
Is there any way for modeling wind surface tension on water surface instead of modeling wind effect through UDF?

By September 2014, KSB, Germany, will supply eight boiler feed pumps for the new power station in Babelan, Indonesia. The 270 MW oil-fired power station is being built by a Finnish corporate group approximately 20 kilometres east of Jakarta. The order is for the supply of eight boiler feed pumps of which six will be driven by fixed speed 6,000 V electric motors with a 2,260 kW drive rating. To adjust the speed to the varying pump output required, the pump sets have been designed with a turbo coupling between pump and motor. The flow rate of each unit will be around 270 m³/h. The designed head is approximately 1,960 metres and the temperature of the fluid handled 160 °C. The impellers of the 11-stage pumps are made of stainless steel. The total weight of each unit consisting of a pump, coupling and motor is in the region of 25 tonnes.


New Delhi, May 17 (PTI) The water level in 91 major reservoirs across India has gone down to 19 per cent of their total storage capacity from 20 per cent last week, the Union Water Resources Ministry said today.
There is 31.072 billion cubic metres (BCM) of water available in the reservoirs (as of today), according to a statement issued by the ministry.
The latest levels in the reservoirs are 85 per cent of the storage reported in the corresponding period last year, the ministry said.
It is also 90 per cent of the decadal average of the storage.
The reservoirs in states such as Himachal Pradesh, Punjab, Jharkhand, Odisha, Gujarat, Uttar Pradesh, Madhya Pradesh, Chhattisgarh and Telangana have reported lower water levels than last year.
Major dams in Rajasthan, West Bengal, Tripura, Maharashtra, Uttarakhand, Andhra Pradesh Karnataka, Kerala and Tamil Nadu have reported better storage vis-a-vis last year.
The total storage capacity of all the major reservoirs is 161.993 BCM, which is about 63 per cent of the total storage capacity of 257.812 BCM, estimated to have been created in the country.
Of the total major reservoirs, 37 have hydropower benefit with installed capacity of more than 60 MW. PTI ENM ENM KJ KJ


ROCHESTER, Minn.- It's a project that will prevent serious flooding in Rochester, dredging of the Zumbro River starts today.
Megan Moeller works for the Rochester’s Public Works Department and tells KIMT they're closing certain parts of trails along the Zumbro River.
One trail closing during the project is the bike trail near the government center. The city is removing sediment, which helps prevent major flooding if heavy rain happened.
If the city didn't dredge the river the water could leave the channel, potentially causing serious impact on area business and homes. “If and when there's a flooding event in the future the flood control project is working as it should be,” she added.
This will be the fourth time the entire channel was dredged and is expected to be completed December 31st.

The stationary part of the seal is fixed in the pump housing. It consists of a stationary seat and a stationary secondary seal.
The stationary part of the seal is fixed in the pump housing. It consists of a stationary seat and a stationary secondary seal. The secondary seal prevents leakage between the stationary seat and pump housing. It prevents the seat from rotating in the pump housing as well.
The pumped liquid (A) is generally in contact with the outer edge of the rotating seal ring (B). When the shaft starts to rotate, the pressure difference between the liquid (A) in the pump housing and the atmosphere (D) forces the liquid to enter the sealing gap (from B to C) between the two flat rotating surfaces. A lubricating film is generated.
The pressure in the sealing gap is reduced from B to C, reaching the pressure at D. Leakage from the seal will appear at out in the air.
The parts of the seal inside the pump are subjected to a force emanating from the pressure within the pump. The axial composant of this force, together with the spring force creates the closing force of the seal.

BATON ROUGE, La. (AP) " A timeline has been set for construction of a flood-control canal in Louisiana that has been sought for decades.
The Advocate reported Wednesday that engineers with the Comite River Diversion Canal project say it will be completed by the summer of 2021. The project has been considered since the Amite and Comite rivers flooded in 1983.
Record floods in the same area two years ago brought renewed attention to the $450 million project, which was granted $343 million in federal funding this year. Officials say this award coupled with already secured funding is enough to begin construction.
U.S. Army Corps of Engineers project manager P.J. Varnado says construction may begin in February or March. The 12-mile (20-kilometer) diversion canal will redirect high water from the Comite River to the Mississippi River.

|Title:||Investigation of leakage flow in centrifugal blood pump||Authors:||Teo, Jimmy Wei Long||Keywords:||DRNTU::Engineering::Mechanical engineering||Issue Date:||2015||Abstract:||Miniaturization of third generation centrifugal blood pump is important as a smaller pump allows for a less invasive and complicated surgery. Furthermore, it will allow the blood pump to be fitted into people with small chests such as children and women. Therefore, it is important to study the leakage flow characteristics in smaller pumps to prevent haemolysis and thrombus formation. In this study, two smaller pumps of 40mm and 45mm diameter impeller is designed and fabricated to be tested alongside the original 50mm diameter impeller pump. The impeller width of the smaller pumps is increased to compensate for the lower volumetric efficiency. Leakage flow analysis is done by using both the impeller and dummy impeller. The impeller measures the pressure difference in the clearance gap (mean ΔP) of the real pump with regards to the operating flow rate. The dummy impeller is used to measure the mean ΔP with regards to leakage flow rate. This is achieved by operating the pump with the dummy impeller in a reverse flow condition. The reverse flow condition is created by an auxiliary pump unit and the flow rate measured from the outlet of the pump can then be interpreted as the total leakage flow rate. The results obtained from the impeller show that the mean ΔP slightly decreases with increasing operating flow rate. The results obtained from the dummy impeller show that there is a linear relationship between leakage flow and mean ΔP with a positive gradient. From the results of the impeller and dummy impeller, the leakage vs operating flow rate can be obtained by relating them at the similar mean ΔP. The results obtained shows that leakage flow slightly decreases with increasing operating flow rate and is maximum when operating flow rate is zero. The experimental results are then compared with the Computational Fluid Dynamics (CFD) simulation results. From the comparison, it is observed that the CFD simulation is able to predict the experimental leakage flow for the 0.2mm gap size fairly accurately. It is also observed that as the gap size increases, the error between CFD and experimental data increases. Lastly, it is noted that the CFD is unable to predict the leakage flow of the 0.5mm gap due to the large deviations obtained. This is attributed to the negligence of the inertia forces which is more dominant at large gap sizes. In conclusion, the method of measurement conducted in this experiment shows good agreement with the CFD simulations in the region of the normal operating flow rate (5L/min) for the 50mm pump with 0.2mm, 0.3mm and 0.4mm gap sizes. However, the 0.5mm gap size shows a large deviation between CFD and experimental method. Lastly, the large gap sizes of 0.4mm and 0.5mm shows low volumetric efficiency as their leakage flows are higher if not almost as high as the operating flow rate.||URI:||http://hdl.handle.net/10356/64603||Schools:||School of Mechanical and Aerospace Engineering||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|

Lysander, NY – The second phase of the Dexter Parkway drainage improvement project is near completion.
Lysander Supervisor Barry Bullis said the project has been a work in progress for years now. Phase II is a continuation of the phase I box culvert project installed under Route 370 last year.
The completion of the project will bring relief to the chronic flooding problem at the foot of Dexter Parkway and flooding at upstream intersections that occurs during major rain events. As part of the project, sump pump discharge connections to the closed drainage system will be provided to homes along the route. This will help eliminate water discharge on the roadways and reduce severe icing problems during the winter.
The pipeline portion of the project is also nearly complete. The decades old pavement will be removed and new asphalt binder will be installed by the Lysander Highway Department. Current plans call for the asphalt top course to be installed in the spring of 2012, Bullis said in a news release.
Bullis also thanked the New York State Department of Transportation for creating a positive working environment with the town.

India has a history of about 120 years of hydropower. The first small hydro project of 130 kW commissioned in the hills of Darjeeling in 1897 mark the development of hydropower in India. The Sivasamudram project of 4500 kW was the next to come up in Mysore district of Karnataka in 1902, for supply of power to the Kolar gold mines. Following this, there were number of small hydro projects set up in various hilly areas of the country. Till the Independence (1947), the country had an installed capacity of 1362 MW, which included 508 MW hydropower projects, mainly small and medium. As per MNRE, the estimated potential of small hydro power plant is 20 GW across the country.
Depending upon the capacity of the project, a Small hydro Project can be classified as below:
Small streams with steep bed slopes are available in the hills, giving rise to medium as well as high head projects utilising small discharges. These schemes are normally run of the river type with a small diversion structure to divert the flows through the head regulator located in the intake portion of the diversion structure. The water conductor system would usually comprise of a diversion and head regulator, a power channel, a desilting basin, forebay, penstock, power house and a tail race leading from the power house to the stream.
Irrigation canals carrying relatively high but assured discharges have several falls along their route. Small hydel projects utilising low heads can be constructed at such falls. Small hydel projects can also be located just downstream of a dam, barrage or similar structure to utilise the difference in the water level in the reservoir and in the canal downstream. A bypass channel to bypass the flows adjacent to the fall structure is constructed and the power house is constructed in the bypass channel. The bypass channel is suitably connected to the main channel.
The Union Cabinet, chaired by the Prime Minister Narendra Modi, has approved following Measures to promote Hydro Power Sector:

Dasu Dam inaugurated
Prime Minister Nawaz Sharif has laid the foundation for the Dasu power project in Kohistan. The dam will make a contribution towards meeting the shortfall of electricity in the country.
At the groundbreaking ceremony of the 4,320 megawatt power project, Nawaz said that hydel resources will be fully exploited in order to overcome the country’s electricity crisis.
The World Bank has agreed to provide assistance worth $1 billion for the project, which is expected to be completed in two phases; the first phase will be completed in five years and will add 2,160MW electricity to the national grid.
Over the next few years, an additional 40,000 megawatts of electricity could be generated from new power projects on the Indus River. At present, only 7,000 megawatts of electricity is being generated from this source.
The Dasu project is part of the least-cost energy production plans of Wapda aimed at harnessing the country’s hydropower resources to generate environmentfriendly electricity and to improve the share of hydroelectricity in the energy mix.
The project will be constructed on the Indus River, seven kilometres upstream of Dasu village and 74 km downstream of Diamer-Bhasha Dam. According to a statement issued by Wapda, the project will generate 21.3 billion units of electricity per annum and will also have a positive impact on existing hydropower stations such as Tarbela, Ghazi Barotha and Chashma.

High-Efficiency Hydraulic Power Transfer Units for Multisystem Aircraft 791056
Many contemporary aircraft requiring multiple hydraulic systems for power redundancy have utilized hydraulic power transfer units to provide that service. These units, which are commonly called reversible motor pumps (RMPs), have been heavy, noisy and inefficient with generally very poor differential pressure startup characteristics. A new-generation RMP that has solved many of these problems has been developed for the Douglas DC-9 Super 80 Series aircraft. The new unit emits significantly less noise than existing comparable units and is both weight- and cost-competitive, with excellent startup and running characteristics. It will provide an excellent means of attaining pumping redundancy in future hydraulic system configurations.


The Hydroelectric power plant will be an energy storage facility with a turnaround efficiency of 78.9% that utilises the water stored in the upper dam, which is converted to kinetic energy during the flow of water through the 1.2-kilometre subterranean tunnel
Dubai Electricity and Water Authority (DEWA) has announced that the work progress of the pumped-storage hydroelectric power plant being built by DEWA in Hatta, has reached 52.61%. DEWA also announced the completion of the construction of the 72-metre main Roller Compacted Concrete (RCC) wall of the upper dam. DEWA has also completed the construction of the 37-metre-high RCC side wall at the project’s upper dam. The hydroelectric power plant will use the stored water in Hatta Dam, and the upper dam that is built in the mountain to produce electricity. The plant will have a production capacity of 250 megawatts (MW), a storage capacity of 1,500 megawatt-hours and a life span of up to 80 years. This is the first station of its kind in the GCC, with investments up to AED 1.421 billion. The project is planned for completion by the fourth quarter of 2024.
HE Saeed Mohammed Al Tayer, MD & CEO of DEWA, said that the pumped-storage hydroelectric power plant in Hatta is part of DEWA’s efforts to achieve the directives of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, to achieve the Dubai Clean Energy Strategy 2050 and the Dubai Net Zero Carbon Emissions Strategy 2050 to provide 100% of Dubai’s total power production capacity from clean energy sources by 2050. The project supports the comprehensive plan to develop Hatta and meet its social, economic, developmental and environmental needs, in addition to providing job opportunities for citizens in Hatta.
Al Tayer noted that the hydroelectric power plant in Hatta is part of the projects and initiatives launched by DEWA to diversify energy production from renewable and clean sources in Dubai. These include different technologies such as solar photovoltaic panels, concentrated solar power, and green hydrogen production using renewable energy.
The Hydroelectric power plant will be an energy storage facility with a turnaround efficiency of 78.9% that utilises the water stored in the upper dam, which is converted to kinetic energy during the flow of water through the 1.2-kilometre subterranean tunnel. This kinetic energy rotates the turbines and converts mechanical energy to electrical energy which is sent to DEWA’s grid within 90 seconds in response to demand. To store energy, clean energy generated at the Mohammed bin Rashid Al Maktoum Solar Park will be used to pump the water through this tunnel back to the upper dam by converting the electrical power to kinetic energy making the whole project 100% renewable.

In the Wanta-Sunglin hydropower project of Taiwan Power Company, a 5,947m-long tunnel passing through metamorphic slate formations was constructed by NATM method. Before the breakthrough of this tunnel in 2011, due to the variation of geological conditions, the excavation was blocked by shear zones with squeezing and creeping effects, until remedial measures and supporting adjustment were applied. Beside the difficult geological conditions, part of the alignment of this tunnel underpasses the Chuoshui River, which makes the support design even more challenging. This paper summaries the support designs, the tunnel deformation instrumentation, and the feedback analysis. In addition, the treatment and reinforced adjustment for the sections of river underpassing and shear zones were also illustrated and discussed. The experiences learned from this project can contribute to the other newly-built or rehabilitation hydropower projects in a similar situation.
In order to more efficiently obtain the hydropower from the Wushe Reservoir, which is situated at the upstream of Chuo-Shuei River, Taiwan Power Company planned and constructed the Wanta-Sunglin hydropower project. It comprises the extension of Wanta hydropower plant and the newly built Sunglin hydropower plant. In the former Wanta extension project, a new intake shaft was built with a new tunnel passage to the power plant. And a long tunnel from the new Sunglin Weir to a new underground plant were built in the latter Sunglin project. The total length of tunnels built in the Wanta- Sunglin project is 5947m, see Figure 1. For the objectives, this hydropower project can generate green electrical power 0.125 billion KWH per year. In contrast with hydrocarbon generated power, this project can reduce the emission of CO2 by 67000 tons per year. In addition, as part of the hydropower system, it can improve the operation of the water reservoirs, in which the water for irrigation and utility usages can be more flexibly supplied.


The Ingula plant is being built about 350km south east of Johannesburg, on the border between KwaZulu-Natal and the Free State. It is scheduled to be operational in 2013.
Impregilo said that the construction contract was worth approximately Euro600M (US$795M), and it has a 40% stake in the JV.
The project involves linking the Bedford Stream upper reservoir to the powerhouse via an approximately 2km long headrace tunnel. The water will be discharged to a lower reservoir through a tailrace tunnel of about the same length.
Construction works on the scheme include caverns, tunnels, adits, shafts and penstocks, installation of the pump-turbines, and construction of the dams for the upper and lower reservoirs.
Last year, Eskom awarded Voith Siemens Hydro Power Generation the contract to supply electro-mechanical equipment to the project. The plant will be supplied with four pump-turbines, each of 342MW rated output, in a contract worth approximately Euro140M (US$186M).
From today, Voith Siemens Hydro Power Geneartion - which is a joint venture - operates under the new brand name of Voith Hydro.

Blackfoot Dam facts for kids
Blackfoot Dam (National ID # ID00204) is a dam in Caribou County, Idaho, in the eastern part of the state.
The earthen dam was completed in 1911 by the United States Bureau of Indian Affairs, with a height of 55 feet and 304 feet long at its crest. It impounds the Blackfoot River of Idaho for flood control and irrigation water storage primarily for the Fort Hall Indian Reservation. The dam is owned and operated by the Bureau. Its construction came eight years before the 1919 formation of Caribou County.
The reservoir it creates, Blackfoot Reservoir, has a water surface of 18,000 acres, and a maximum capacity of 413,000 acre-feet. Blackfoot Dam impounds the river at the northwestern end of the reservoir; the China Hat Dam towards the southwest of the reservoir was constructed in 1923 to resolve seepage problems. Recreation includes fishing for rainbow and cutthroat trout, as well as carp.

Modelling the Catchment Areas and Drainage Networks By Just One Process
Through Nethydro, only digital terrain model is enough for modelling the catchment areas and the flow models of your working area. By just one process, you can model the main catchments, catchments, sub-catchments and the drainage networks feeding these catchments. Catchment area and drainage network modelling could be also be realized according to a chosen point on digital terrain model.
In analyses conducted as per D8 Flow Model, the cumulative flows and flow directions can be automatically calculated for each catchment area, data such as harmonic slope, length, etc. for catchment area and perimeter, catchment vector, catchment shape, flow arms obtained for catchment areas can be easily obtained from the database.
Catchment areas can be classified as main catchment, sub catchment, etc. based on the number of cells and the size of the catchment.
