Damodar River of India is popularized as ‘Sorrow of Bengal’ due to massive unpredictable destruction in the monsoonal floods, recorded since 1665.Taking three prime objectives of development: (1) flood control, (2) extensive irrigation and (3) power generation, Damodar Valley Corporation (DVC) was established in 1948 as India’s first multipurpose river valley project on the Damodar River Basin. Four large dams, Durgapur barrage and Tenughat reservoir are built to tamp the flood prone Damodar River using the water resource in an integrated method. Carrying sixty years of legacy, the existing drainage and flood control system of DVC has aggravated a number of hydrogeomorphic problems especially in the lower segment of Damodar, viz., siltation of river bed and reservoirs, uncontrolled monsoonal stream flow, declining carrying capacity of lower course, drainage congestion, low-high magnitude annual floods, decay of palaeochannels etc. Highlighting the existing problems, this research work mainly tries to analyze the pre-dam and post-dam flood hydrology and risk assessment of Damodar River Basin which can be applied in the flood management strategies of West Bengal.

This paper aims to evaluate the applicability of dam inflow prediction model using recurrent neural network theory. To achieve this goal, the Artificial Neural Network (ANN) model and the Elman Recurrent Neural Network(RNN) model were applied to hydro-meteorological data sets for the Soyanggang dam and the Chungju dam basin during dam operation period. For the model training, inflow, rainfall, temperature, sunshine duration, wind speed were used as input data and daily inflow of dam for 10 days were used for output data. The verification was carried out through dam inflow prediction between July, 2016 and June, 2018. The results showed that there was no significant difference in prediction performance between ANN model and the Elman RNN model in the Soyanggang dam basin but the prediction results of the Elman RNN model are comparatively superior to those of the ANN model in the Chungju dam basin. Consequently, the Elman RNN prediction performance is expected to be similar to or better than the ANN model. The prediction performance of Elman RNN was notable during the low dam inflow period. The performance of the multiple hidden layer structure of Elman RNN looks more effective in prediction than that of a single hidden layer structure.

The regulation of hydro power plants is influenced by amongst others reservoir capacity and the knowledge about how it is influenced by changes in in- and out?ow. The hydro power reservoir Aurdalsfjord has a small capacity compared to the inflow, a narrowing between inflow in the north and outflow in the south and has implemented strict governmental restriction. The paper will present a reservoir model that was developed in order to investigate the water ?ow and water level conditions in Aurdalsfjord. The water level in each cell is described with a mass balance, while the flow between two cells is described with a momentum balance. The balance equations are formulated as DAEs. The model is developed in Modelica which allows it to be used in connection with models of a wide variety of other components that are present in a hydro power system. The model will be integrated in the open-source hydro power library OpenHPL developed at USN. The Modelica model shows promising results. For Aurdalsfjord it needed to be adjusted with non-physical parameters. The reservoir model should be implemented for a less complex shaped reservoir in order to see if the challenges are related to the Modelica implementation or Aurdalsfjords shape.

The District conducted the Laveen Area Drainage Master Plan/Update (ADMP/U) to develop and evaluate alternative solutions to mitigate flooding hazards in the Laveen Area. This project is one of the recommend solutions from the ADMP/U to reduce the impacts from flooding.
This project recommended constructing two detention basins for both the east wash (Highline Basin) and the northeast wash (Carver Basin). The basins will be built with a storage volume sufficient to hold the 10-year return frequency. Both basins will drain or ‘bleed off’ with a 30-inch diameter storm drain pipe. The storm drains from each basin would join at 45th Avenue and Estrella Drive and the combined flow would be conveyed in a 36” diameter storm drain pipe along Estrella Drive from 45th Avenue to the SR202L Freeway channel. As the project design is refined, these particular features may be modified or changed.
The project is located within unincorporated Maricopa County and the District will be the lead agency for the design and construction of the project.

Climate change will increasingly question flooding or water shortage. The Delta Programme 2015 water retention is mentioned as one of the measures to reduce the risks of both too much and too little water. For temporary storage of water during high water levels, many places are already used as specially designed water storage areas. These areas are largely dry during low water levels in order to be optimized for water storage when needed.
Is it possible to temporary store peak floods and simultaneously hold precipitation surplus as long as possible in the same area? RichWaterWorld developed a new concept for integrated water storage and retention. This concept has been implemented as an advisory tool for anticipatory water management.


Theoretical and empirical burst pressure prediction models are developed.
The models quantify effect of defect geometry and orientation on burst pressure.
Burst pressure experiments are used to validate the model predictions.
Axial defect is more detrimental to burst pressure than circumferential defect.
Accurate prediction of the burst pressure is essential for structural integrity assessment of pipelines. Current design codes and models for residual burst pressure assessment of pipelines with surface corrosion defects are only applicable to axially orientated defects. Theoretical and empirical models for the prediction of burst pressure of thin-walled pipes with pre-existing localised and arbitrarily oriented surface corrosion defect are proposed. The theoretical model is based on power-law hardening and J2 flow theory while the empirical model is derived from nonlinear finite element analysis results of the burst pressure. Burst pressure experiments are used to validate the model predictions. The theoretical and empirical models are found to be reliable in predicting the effect of defect width, length, and orientation on the burst pressure.


A project to replace one of the Bay Area's oldest dams is now underway. --Calaveras Dam and Reservoir is located east of Milpitas, along the Santa Clara-Alameda County lines. Friday, crews broke ground on the project to replace the 86-year-old earthen barrier. The project is critical, considering the old dam was ruled seismically unsafe 10 years ago. The dam holds back the reservoir which is San Francisco's largest local source of drinking water. The $416 million project is scheduled to be completed in 2015.

Renewable energy firm Iberdrola has started the construction phase at San Pedro hydroelectric plant extension project in Galicia, Spain, to increase the facility’s capacity to 57MW.
Located in the river Sil, in the municipality of Nogueira de Ramuín (Ourense), the plant acts as a reservoir for Santo Estevo by controlling the river flow.
The new construction phase, known as San Pedro II, will add 25MW to the existing facility, which currently has an installed capacity of 32MW.
Iberdrola will invest €52m to construct the new plant, which will be partially situated underground.
The company previoulsy opened the largest hydroelectric complex in Galicia, which has 441MW installed capacity.
The hydroelectric power plant has the capacity to generate around 1,000GWh of electricity per year, enough to power approximately 285,000 homes in the region.
Built completely underground, the extension of the original plant, now referred to as Santo Estevo II, is integrated into the surroundings, which include the Sil River canyon.
Santo Estevo II will optimise existing infrastructures, which include a dam, reservoir, substation and export power lines, with a capacity of 176.9MW.
Iberdrola said after completion, the projects will fulfil its objectives to achieve sluice control, balancing flows downstream and optimising exploitation of a renewable energy source.
The company has invested more than €1.1bn in Galicia and made purchases of €1.2bn from more than 200 local providers in the past decade.

To make energy available for pumping, we could set up solar power generation facilities near these reservoirs which will provide the energy needed during the day (off-peak period) to pump water from the lower reservoir. to the upper tank.
Since a different energy source is used for pumping, the term hybrid pumped storage system is used. During the day, solar panels would generate the energy needed to pump water from the lower reservoir to the upper reservoir.
The same water would then be released to generate power to increase the power supply to the grid to meet the demand for the two daily peaks; morning peak from 7:00 a.m. to 8:30 a.m. and evening peak from 6:00 p.m. to 10:00 p.m.
Indeed, in one of my previous articles on flood mitigation in the Kashmir Valley, I had suggested the construction of a series of small dams or cascading reservoirs on the main rivers as well as on their tributaries which could ensure flood moderation.
These same cascade reservoirs could be appropriately designed to also serve as reservoirs for pumped storage. In fact, these reservoirs would be like multi-purpose systems in that they would help with flood moderation, sediment control and at the same time increase our electricity production, especially during times of peak demand.
In addition, the area around them could be developed into recreational and tourist places.

Sources told Capital that the feasibility study of the two power plants is being finalized and the government is looking for financers for the project that will consume billions of dollars.
The projects that will be managed by the Ethiopian Electric Power will have a generation capacity of 1470 MW (Gibe IV) and GIBE V will have a capacity to generate 660 MW.
“These two dams will be the next big projects of the country right after the commissioning of Gibe III which does have a generating capacity of 1870 MW,” sources said.
The Gibe III hydropower project is now more than 80 percent complete. It is expected to start generating power early next year, when its first turbine becomes operational. The other nine turbines will be installed and become fully operational by April 2016. The power house of the project contains 10 units each having a capacity of producing 187 MW.
The Gibe III Hydro-power project, with its potential to double the current electric power generating capacity of the country, is a key part of Ethiopia’s 5-years Growth and Transformation Plan (GTP).
The financial costs of the dam and hydroelectric power plant have been estimated to be 1.55 billion Euros. The cost of a transmission line from the power plant to the nearby Wolayta Sodo Substation has been estimated at 35 million Euros.
Gibe III when completed, will supply power need for neighboring countries such as Kenya with cheap power.
Currently Ethiopia is building Africa’s largest dam (The Grand Ethiopian Renaissance Dam) on the River Nile, which is a controversial issue between Ethiopia and Egypt. GERD when commissioned will have an installed generating capacity of 6,000 MW.


This year’s OPA will be presented to representatives of both the U.S. Army Corps of Engineers (USACE) and the Treviicos-Soletanche Joint Venture (TSJV). The project was nominated by the two organizations, making it a double winner.
Wolf Creek Dam is on the Cumberland River in south central Kentucky. The dam and its adjacent reservoir reside upon a heavily Karst bedrock foundation. The USACE placed the dam under a 'high risk' for failure designation and launched a $584 million major rehabilitation program. The dam was plagued by leaks and repaired many times before the successful engineering solution was completed.
The main contract was awarded in 2008 to Treviicos-Soletanche Joint Venture for the construction of a 980,000 sf concrete barrier. The concrete barrier wall was built using eight different techniques including: high mobility grouting, low mobility grouting, clamshell excavation, hydromill excavation, directional drilled pilot holes, auger drilling, reverse circulation drilling and verification coring drilling.


The project name is Alce and it is located in Turkey. The assignor is AİDA Enerji San. ve Tic. Ltd. Şti.
According to the contract VAPTECH has to deliver two sets of: turbine, inlet valve, generator, hydraulic pressure unit, automation system as well as supervision of installation works and commissioning. The delivery time for the equipment is 8 months.
Alce HPP will operate under a net head of 209,2 m and a maximum discharge of 3,1 m3/s. The flow will be utilized by two identical Pelton turbines VAPHYDRO™ with 6 injectors and rated speed of 750 rpm. The rated turbine output is 2848 kW. The total installed capacity for the power plant will be 5696 kW.

Manufacturing material of desulfurization pump
The structure of the pump head (including the front and rear pump casings, volutes, front and rear guard plates, impellers, etc.) is different, but the structure of other parts is similar. The same series of transmission parts are used. The following is the structure characteristics of the pump head, shaft seal and transmission parts.
Pump head part
The pump is a double pump casing structure, i.e. the front pump casing, the rear pump casing and the flow passage part (including impeller, volute, front guard board and rear guard board) which can be changed. The front and rear pump casings are made of gray cast iron or nodular cast iron according to the working pressure. They are vertically split and connected by bolts. The rear pump casing has a stop and bracket connected by bolts. The discharge outlet of the pump can be rotated and installed according to eight angles. The front and rear cover plates of the impeller are provided with back blades to reduce disclosure and improve the service life and efficiency of the pump. The inlet of each type of pump is horizontal, and the pump rotates in a clockwise direction according to the driving direction.
Shaft seal part
There are three ways of shaft seal, auxiliary impeller shaft seal and packing shaft seal, mechanical seal.
(1) Auxiliary impeller shaft seal: when the positive pressure at the pump inlet is not more than 10% of the pressure at the pump outlet, single-stage pump or multi-stage series third stage pump can adopt the auxiliary impeller shaft seal. The auxiliary impeller shaft seal has the advantages of non dilution slurry and good sealing effect.
(2) Packing shaft seal: the packing shaft seal is simple in structure and easy to maintain. The shaft seal water needs to be used. The packing shaft seal can be used for the working conditions that are not suitable for the use of the auxiliary impeller shaft seal and the pump suction.
(3) Mechanical seal: mechanical seal is used to reduce the maintenance times of the shaft seal under the condition that it is not suitable for the above two shaft seals.
This series of pumps adopt the same series of transmission, including bracket and bearing components. The diameter of pump shaft is large, the rigidity is good, the cantilever is short, and it will not bend and vibrate under severe working conditions. The single row tapered roller bearing and angular contact ball bearing are used in combination to bear the maximum axial and radial load of the pump. The bearing is lithium Base grease lubrication, the advantages of this lubrication are: high oil film strength; good grease adhesion, not easy to lose, long use time; simple sealing, bearing body with sealed end caps at both ends, can effectively prevent pulp and other dirt from entering the bearing.

APPLICATIONS OF DDSWMM
There is a wide range of applications of DDSWMM. The primary application of DDSWMM would be for the design of new urban drainage systems, with due consideration of minor as well as rare rainfall events. This would include sizing of sewers, analysis of inlet control requirements, determination of flows and flow depth in the major system network, design/analysis of detention storage facilities for runoff control, etc.
The overlwhelming applications
of DDSWMM to date, however, have been for the analysis/evaluation of existing
urban drainage systems, including areas which were not designed according
to the dual drainage principle, and the design of relief measures for both
the minor and the major systems, through a combination of DDSWMM and an
interface with the EXTRAN model.

Client: HES Energy
Total Installed Capacity 9 MW
Pressurised GRP Pipeline
Pressure Relief Valves (PRV)
Yunuslar Regulator and HES project is a diversion type hydroelectric power station that is located in West Black Sea region, inside the borders of Çatalzeytin district of Kastamonu province over the creek of Akçay. Project is planned to make use of the energy potential of Akçay Creek between the altitudes of 240 m and 30 m.
Initially, Yunuslar HES project was planned as two staged. In both stages, currents that are converted by regulator structures are transmitted to the head ponds through canal facilities. In this case, the total canal length of the project is around 14 km. Since in the district where the project will be conducted, the construction of such a long canal line, headpond and transportion line would be hazardous to environment and also too costly, project formulation was revisioned by Prosem Engineering.
As a result of the land and office works of Prosem Engineering, the project is reduced to a single stage and its tranmission line is planned as a pressurised GRP pipeline that will be constructed in a closed station next to the stream bed. Also, it is been agreed to be more economic and feasible to have the water that is converted by the regulator to be transmitted directly to the turbines through this pipeline. A revised feasibility report has been prepared after the project formulation is converted in this way. As a result of these revisions, expropriation costs of the project has been reduced significantly as well as the negative social and environmental effects.
The transission line of the project is 12 km long, thus, the water hammer effect affects the design of the project significantly. For this reason, Prosem Engineering has performed a transient analysis. According to the calculations, in order to maintain the pressure rise in GRP pipe line at a reasonable level, pressure reducing valves (PRV) will be constructed in the powerouse and along the transmission line.

Construction works on the Buk Bijela hydroelectric plant on Drina river should commence this year, said Petar Đokić, minister of industry and energy in the Government of the Republic of Srpska. He added there was determination and that the situation will be different by the middle of the year.
Numerous stories that the government does not have serious intention to build it will be denied by concrete steps, Đokić told Glas Srpske portal. In his words, hydro power plant operator Višegrad will head the project, while the Power Utility of the Republic of Srpska (ERS) will get the concession from the government.
Earlier, ERS head Branislava Milekić said construction works can be expected in a year at the latest, as the main project should be complete by then. The initial project estimated the value of the power plant at EUR 195 million and installed capacity at 93.5 MW, she told Glas Srpske. The main project takes six months, Milekić stated and added the power plant will be financed through loans. As the environmental study is already complete, paired with a solid volume of project documentation, it won’t be difficult to attract financing, she said.


The evaluation of hydrological models for a specific catchment is normally based on the model performance according to the selected performance criteria. However, the catchment rainfall-runoff characteristics could be used for the selection of a suitable hydrological model in study area, which, also, for the problem solve of the model application in ungauged basins. In this study, six conceptual models were applied in three semi-humid or semi-arid catchments to investigate the correlation between catchment characteristics and model structure selection. In addition, the impacts of precipitation and topography in model simulation were analyzed. The results show that runoff generation are highly impacted by catchment topographic index and land cover change, and the influence of slope for river channel is greater than mean slope for the whole catchment due to the runoff generation for partial area. For the catchments under similar climate condition, the impact of topographic features for runoff generation process is greater than the difference of precipitation. It indicates that for a specific catchment, the selection of appropriate model should base on better understanding of the rainfall-runoff relationship. The method of incorporating additional runoff generation module in traditional model can significantly improve the accuracy of flood simulation.


Umgeni Water has reassured residents that there appears to be no imminent problem of water shortages as there seems to be sufficient water at the moment.This comes after messages were being circulated on social networks claiming that there is a critical drought on the horizon that will affect residents in the Howick, Pietermaritzburg and Durban areas.Umgeni Water spokesperson Shami Harichunder said the average total water storage of the Mgeni System was by November 30, 2018, at 67% whereas at the same time a year ago it was at 54%. Harichunder said the Mgeni System was estimated to feed four million consumers in the uMgungundlovu, Msunduzi and eThekwini areas and is the biggest system under Umgeni Water.As of Monday, Harichunder said the water levels at dams under the Mgeni System were as follows: Mearns Dam at 52% full, Spring Grove Dam at 56%, Midmar Dam at 94%, Albert Falls Dam at 40%, Nagel at 59% and Inanda Dam at 62%. He said at the same time last year the dam levels at Mearns Dam was 70%, Spring Grove Dam was at 72%, Midmar Dam was at 77%, Albert Falls Dam was at 19%, Nagel was at 79% and Inanda Dam was at 61%. “The current water level in the Mgeni System is considered acceptable and represents no risk of non-supply,” he said.Harichunder also said Umgeni Water has been experiencing technical problems with their website as some residents had noticed that the daily dam levels were last updated in November 2018. He said they were working on the problem and will be uploading the daily dam levels soon.

Check valves are also known as counterflow valves, check valves, back pressure valves, and one-way valves. This kind of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belongs to an automatic valve.
Uses and characteristics of ball check valve:
HQ44X single-ball micro-resistance ball check valve and HQ45X double-ball micro-resistance ball check valve all use rubber covered balls as the disc. Their principle is that under the action of the medium, they can roll back and forth on the slide in the valve body, thereby Play to open or close the valve. The main features of HQ44X single-ball micro-resistance ball check valve and HQ45X double-ball micro-resistance ball check valve are large flow, small flow resistance pressure loss, good sealing performance, silencing closure, and reduction of water hammer waves. It can be installed horizontally or vertically. The micro-resistance ball check valve can be used at the pump outlets of cold water, hot water, industrial and domestic sewage pipe networks to prevent the medium from flowing back. In order to prevent the medium from flowing back, check valves should be installed on equipment, devices and pipelines
Ball check valve is also called reverse valve, check valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belongs to an automatic valve. The check valve is used in the piping system, and its main function is to prevent the medium from flowing back, preventing the pump and its driving motor from reversing, and to discharge the medium in the container. Check valves can also be used to supply pipelines for auxiliary systems whose pressure may rise above the pressure of the main system.
Product advantages of ball check valve:
1. The fluid resistance is small. The ball check valve is the smallest fluid resistance of all valves. Even the reduced diameter ball valve has relatively small fluid resistance.
2. The check valve is opened and closed quickly and conveniently. As long as the valve stem rotates 90°, the ball valve completes the fully open or fully closed action, which is easy to achieve rapid opening and closing.
3. Good sealing performance. Spherical check valve seat sealing ring is generally made of elastic materials such as polytetrafluoroethylene, which is easy to ensure sealing, and the sealing force of the ball valve increases with the increase of medium pressure.
4. The valve stem is sealed reliably. The valve stem only rotates when the ball valve is opened and closed, so the packing seal of the valve stem is not easily damaged, and the sealing force of the reverse seal of the valve stem increases with the increase of medium pressure.
5. The opening and closing of the ball valve can only be rotated by 90°, so it is easy to realize automatic control and remote control. The ball valve can be equipped with pneumatic device, electric device, hydraulic device, gas-liquid linkage device or electro-hydraulic linkage device.
6. The spherical check valve channel is flat and smooth, and it is not easy to deposit media, and the pipeline can be ball-passed.

Keywords: Pluvial inundation; Ditch; Stormwater drainage box; Numerical simulation;
Abstract: To predict risk level of urban inundation caused by heavy rainfall, so many numerical models have ever been developed. However, there are few models which considers the effects of ditches on inundation flow, which play a significant role in the process of stormwater drainage and overflow. In this study, assuming ditches and drainage boxes on both sides of all streets, a revised inundation flow model is proposed where the storage effects of the ditches are incorporated into stormwater drainage and overflow process.
Between two simulation results, considering and not considering the capacity of ditches, significant difference can be found. Between two simulation results considering and not considering the capacity of ditches, better simulation results could be obtained by using the proposed model here. From those comparison, significant difference between the overland inundation volume between two models could be found, which means the drainage process through the ditches could be expressed appropriately in the proposed model here. The stored water volume in the ditches, equivalent to one fourth to the overland inundation volume, has significant effects on the stormwater drainage process.

Ji, R.; Sun, K.; Wang, S.; Li, Y., and Zhang, L., 2018. Analysis of hydrodynamic characteristics of ocean ship two-unit vertical axis tidal current turbines with different arrangements. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and OceanEngineering. Journal of Coastal Research, Special Issue No. 83, pp. 98–108. Coconut Creek (Florida), ISSN0749-0208.
In order to study the hydrodynamic performance of the two-unit turbinesin different arrangements, a reasonable turbine layout plan was proposed to improve the power generation efficiency of tidal power stations. In this paper, the transient numerical simulation of a three-blade vertical-axis tidal current turbine is carried out, and the hydrodynamic performance of the turbine units with different arrangement (tandem, parallel, and staggered) is analyzed, and the influence of the mutual interference between the turbine units on the efficiency of the power generation is explored. Taking into account the same characteristics of the profile of the vertical axistidal current turbine blades along the extension, the model is simplified to two-dimensional. Firstly, based on the open source software OpenFOAM, a k-ω SST turbulence model and a PIMPLE algorithm are used for a 2D vertical axis tidal current turbine. A numerical simulation method is proposed and compared with the experimental results to verify the correctness of the numerical simulation method. Then the operation of a single turbine was simulated, and the variation of energy utilization with the tip speed ratio and the force characteristics of the turbine during operation were obtained. Finally, the vertical axis tidal turbine units with different arrangements are analyzed in detail, and the energy efficiency, force characteristics, and wake field of the vertical axis turbine units are compared and analyzed. For tandem tidal turbine units, the flow distance Dx of the two-unit turbines is used as a variable to study the effect of tidal turbine spacing on the hydrodynamic performance of downstream turbines. For parallel tidal turbines, the influence of the horizontal distance Dyand three different rotations on the hydrodynamic performance of tidal turbines is studied. For staggered turbine units, the relative distance Dr and the relative position angle ψ of the turbine are used as variables to study the relationship between the capacity of the turbine and the two parameters.

Addis Ababa — The Grand Ethiopian Renaissance Dam (GERD), being built along River Nile, will be completed in 2022, GERD Project Manager Eng. Kifle Horo said.
The dam, in which its construction was launched in April 2011, was initially expected to be completed in 2017.
The project manager made the remark during a meeting held in Addis Ababa on the progress of the GERD project.
However, the construction has delayed due to change in design, which led to the increasing of its generation capacity and delay in the electromechanical works.
Saying that the construction work is being underway without interruption, the 4.8 million USD dam will need additional four years to be completed.
The project manager said that the delay in the hydro-electrical work has also impacted the time where the early generation work started. It will start after two years.
The dam being built in Benishangul-Gumuz Region of Ethiopia, about 15 km east of the border with Sudan, has so far consumed about 98 billion Birr.
At 6.45 gigawatts, the dam will be the largest hydroelectric power plant in Africa when completed, as well as the 7th largest in the world.

The Bergstø power plant has been in operation since December 2009.
There are no regulating storage reservoirs or transfers in connection with this development. The power station is run according to the inflow into the river. A concrete dam was built at elevation 615. The spillway is 2 metres high at the main river, while the dam is 3.5 m high at the intake. The intake was blasted out of the adjacent mountain.
From the intake, a cast iron pipe was laid down to the power station. The entire pipe lies in a rock trench and the inlet pipe is buried along the entire stretch. Work on Bergstø began in June 2008 and put into operation in December 2009.
Only the superstructure of the power station is visible. Outflow from the turbine is led through a short pipe to the culvert under the E-road nearby. The power station is a simple wooden building with a glass façade and faces the main road. A vertical 6-nozzle Pelton turbine with associated 2.9 MW generator has been installed in the station. Flow rate is1.55 m3/s. The waterway has a 700 mm ductile cast iron pipe with a length of 1380 m. The power plant is connected via a 22 kV high-voltage cable in the ground up to the 22 kV line between Odda and Etne. The line runs through the main valley, 150 m from the power station.


Exit blade angle and impeller surface roughness has a significant effect on the performance of a centrifugal pump impeller handling different viscosity fluids. In this paper, a three-dimensional flow simulation using Reynolds averaged Navier Stokes (RANS) equations for the performance analysis of the impeller is reported. The analysis using water and viscous liquids has been accomplished for different flow conditions, exit blade angle and roughness values. Standard k-ε two equation model is used for the turbulent closure of steady incompressible flow. The investigation shows that the blade exit angle has influence on the head, shaft power and efficiency of the impeller for different liquids. Rise in head, increase in shaft power and decrease in hydraulic efficiency have been observed with increasing roughness.
