GEORGE TOWN, April 4 – The Penang State Gerakan Party is concerned with PBAPP’s statement that the capacity of the Air Itam dam is currently only at a low level of 38.5%. Parti Gerakan urged the Penang State Government to study implementing a project to increase water capacity at the Air Itam dam or redraw the water supply area from the 3 main dams in Penang.
At the same time, Parti Gerakan hopes that the state government will not use the issue of high water consumption rates as an excuse to increase water tariffs.
- Air Itam Dam was built around 1958 and completed in 1962 with a water storage capacity of 2.16 billion liters.
- Mengkuang Dam which was completed in 1985 with a water storage capacity of 22 billion liters. After the dam upgrade project which started in 2014, the dam’s water storage capacity is 86.40 billion liters.
- The Teluk Bahang Dam was completed in 1999 with a water storage capacity of 18.24 billion liters, it is 8.9 times the water storage capacity of the Air Itam Dam.
- The population around Air Itam area has increased since 1962 where the water storage capacity of Air Itam dam is still at the same level since 60 years ago, of course water consumption around Air Itam area shows an increase.
- Rainfall distribution in the water catchment area of Air Itam dam is decreasing, will the state government find new water sources in nearby areas with higher rainfall distribution to be channeled to Air Itam dam?
- Apart from the water storage level in the Air Itam dam is below 40%, the water storage level in Teluk Bahang dam is still above 70%and Mengkuang Dam is still above 90%.
- Parti Gerakan has proposed that the state government study the feasibility of carrying out the Air Itam dam upgrade project and redraw the water supply area from the three main dams in Penang. At least the support water supply from the Teluk Bahang and Mengkuang dams in the summer which is usually in March to June.
- The State Government needs to take seriously the Gerakan Party’s proposal because areas in Bukit Kukus, Paya Terubong and Bandar Baru Air Itam are likely to have new housing projects around the expressway project in Paya Terubong and Bandar Baru Air Itam．At that time, the Air dam itam certainly could not meet the increasing needs.
- The Gerakan Party argues, it is not wrong for the state government to call on its people to save water, but it should also take into account the population increase factor in the area as it will lead to an increase in water consumption.
- The incident of underground pipe leaks is also one of the issues taken seriously by the people.
Penang State Gerakan Party Youth spokesman Ivan Kung Cheng An and Batu Lanchang State Assembly Penang Gerakan Party spokesman Mike Chen were also present at the press conference.


Welsh civil engineering firm Alun Griffiths has started work on the Bath Quays Waterside project, a collaboration between the local council and Environment Agency to reduce flood risk.
The firm will change an existing one-way system into a two-way system, including constructing a new road link. This will divert traffic from another area, which will allow the widening of the River Avon’s bank. Work is expected to be completed before the summer.
The project aims to reduce flood risk as well as improve the riverside with a new park and allow the development of a new business district.
Paris-based engineering and architectural consultancy Marc Mimram has won a competition to design a new bridge over the River Avon (pictured) that will form part of the new Bath Quays business district.

Supercritical Flow at Open-Channel Junctions; Hydraulic Model Investigation
ARMY ENGINEER DISTRICT LOS ANGELES CA
Pagination or Media Count:
This report describes hydraulic model tests made to generalize and verify the hydraulic design of confluence structures. Model investigation of certain confluences showed unsatisfactory flow conditions involving considerable turbulence in the confluence structure and transverse waves in the channel downstream. Major changes in particular designs were effected. Various schemes were introduced in each case. Lengthening the transition downstream from divider wall and minimal angle of intersection of the two channels were found to be the most efficient solutions.

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.

Model-driven forecasting used for flood risk assessment or river hydropower systems management, can produce bad results due to many model uncertainties. False inflow and lateral inflow data and/or poor estimation of initial conditions are some of the uncertainty sources. To improve model-driven forecasting, data assimilation methods are used for updating model (e.g., water levels) according to measurements. Widespread data assimilation methods (EnKF, Particle Filter) often increase computational time, which creates difficulties in everyday application of these methods in hydraulic modelling. This paper presents novel approach based on indirect model update adding correction flows at observation locations. This novel, tailor-made, assimilation approach uses proportional-integrative-derivative controller’s theory as algorithm for correction flow calculation. Using indirect approach for model update has justification in models where multiple inflows, including lateral inflows, a...re bad estimated or even neglected. This novel approach is tested on 170km long section of Danube model in Serbia, showing good performance.

Based on the characteristics of large flow rate, low head, short annual operation time, and high reliability of the city flood-control pumping stations, a new-type shaft tubular pumping system featuring a shaft suction box and a siphon-type discharge passage with a vacuum breaker as the cutoff device was developed, which possesses such advantages as simple structure, reliable cutoff, and high energy performance. Taking some pumping stations as the case studies, in the light of the specified operation conditions, the hydraulic optimal design of the shaft-type tubular pumping system was determined and the optimized shape of the system was recommended. The performance prediction based on the computational fluid dynamics methodology was determined and the model test verification was conducted. The results show that the predicted data agree with the experimental head and efficiency so that both methods can be used to determine the performance of a real pumping station. Finally, the in-situ measurements of a pumping station during the commissioning period further verified that the shaft-type tubular pumping station with a siphon discharge passage is of higher efficiency, more reliable and stable.

The Uzbek government plans to construct new hydroelectric power plants and to modernize existing ones under the hydropower engineering development program for 2016-2020.
The construction and modernization of HPPs in the system of Uzbekenergo JSC and the Agriculture and Water Resources Ministry in 2016-2020 will allow to save hydrocarbon resources through the further diversification of fuel balance of the country.
In addition, it will also ensure technical and technological re-equipment for HPPs and create new generation capacity in hydropower with the use of modern energy-efficient technologies, adopting the latest achievements of world practice.
The program envisages building of nine new hydropower plants and upgrading 15 existing hydropower plants with a total capacity of 1,014 MW and preliminary cost of nearly $890 million.
Uzbekenergo JSC will implement 15 projects with a preliminary cost of over $576 million and a design capacity of 943 megawatts within the program in 2016-2020.
Among the projects, the company will implement four projects for the construction of new HPPs worth $69.5 million and a capacity of 23.5 megawatts and eleven projects worth $507.11 million, which are directed to modernize the capacity of the existing plants.
The implementation of projects will increase the capacity of the hydroelectric power plants by 919.9 megawatts.
Uzbekistan’s Ministry of Agriculture and Water Resources will implement nine new hydropower plants with the preliminary total cost of $312.8 million in the coming five years.
The ministry will construct new hydro power plants with design capacity of 70.9 megawatts as part of five projects. The preliminary total cost of these projects is $174.1 million.
Uzbekistan Prime Minister Shavkat Mirziyayev signed a decree on the hydropower engineering development program in 2016-2020 on November 16, 2015.
The program will be financed through the funds of the Ministry of Agriculture and Water Resources and Uzbekenergo JSC in amount of $478.16 million and borrowings worth $411.25 million.
Currently, 45 power plants with the capacity of nearly 13,000 megawatts, including 16 power plants of Uzbekenergo with the total capacity of 12,040 megawatts, operate in Uzbekistan’s power supply system.
Up to 90 percent of electricity is produced by 10 thermal power plants of Uzbekenergo with the total installed capacity of 11.6 million kilowatts. The company’s 29 hydropower plants with the installed capacity of 1.4 million kilowatts are mostly united within hydropower plant cascades.
The rest of the electricity is generated by autonomous thermal power stations of the industrial enterprises and small hydroelectric power stations belonging to the Ministry of Agriculture and Water Resources.
In 2014, electricity production in Uzbekistan increased by 2.3 percent - up to 55 billion kilowatt-hours.

Rainwater harvesting for new surgery in Sutton Ashfield
Aquaco Water Recycling will be supplying rainwater harvesting equipment to the New Street Doctors’ Surgery in Sutton Ashfield to allow rainwater to be collected from the 330m2 roof and used for lavatory flushing.
The rainwater harvesting system supplied consists of an underground rainwater collection tank with internal filters and pump sets which will be controlled by float switches and a control panel. There is also a mains water top up for dry spell periods. The top up is set to replenish the water supply when the tank reaches a pre-determined low water level during dry spells.


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.

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.

Large Cooling Water Pump Upgrade for Increased Capacity And Reduced Impeller Cavitation
This case study discusses the hydraulic upgrade of two sets of four (25 percent) large vertical cooling water pumps. To increase the electrical output of subject power station, the cooling water pumps of block 1 and 2 had to be upgraded in capacity minimally thirteen percent, thereby also attempting to minimize the occurrence of impeller cavitation. The upgrade consisted of replacing the existing impeller and diffuser plus casing, and installing new electric motors. To corroborate anticipated hydraulic performance the replacement impeller and diffuser were model tested on a 1:4 scale. The model test further served to determine final sizing dimension of the upgrade.

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.

The Maintal flood channel system
The plan for the extension of the Maintal flood channel system includes the existing channels. The flood channels are deepened and connected to an outflow-effective flood system. The terrain modelling of the Maintal flood system tray offsets the reductions in the retention area following the construction of the new line and offers enough storage space for the anticipated water quantities in the event of flooding.
Comprehensive conservation-related compensatory measures are planned in order to compensate for the impact the projects will have on nature in the Maintal region. These include in addition to terrain modelling of the channels, the cultivation of natural, ecologically high-value pasture vegetation, grass seeding for soil stabilization, succession areas that will be left for nature to encroach upon, and plantations with native tree and shrub species.

PANCHTHAR, Nov 29: Construction work of Hewa ‘A’ Hydropower Project (15 MW) has been completed.
According to Pushpa Jyoti Dhungana, chief of the project, 10 MW of hydropower generated by the project will be connected to the central grid within this week.
“The project will be connected to the 33 kVA transmission line now as the 133 kVA Kabeli Corridor Transmission Line is yet to be ready. Power generated by the project will be connected to the central grid through the Kabeli Corridor once the transmission line project is completed,” added Dhungana.
Project officials released water into the project’s 3,936-meter tunnel on Monday.
Dhungana said that the project will start generation after trial run of the powerhouse is completed. The project will be officially inaugurated in mid-December, according to Dhungana.
The project went into the floor in April 2013.
Dhungana told Republica that the project was delayed a bit due the 2015 earthquakes and the Indian blockade. “The delay escalated the project cost to Rs 2.25 billion from the initially estimated Rs 2.16 billion,” Dhungana said, claiming that the Hewa ‘A’ project completed comparatively faster than other hydroelectricity projects in the country.
Panchthar Power Company owns 25 percent stake in the company. Similarly, a consortium of banks led by Sanima Bank Ltd has financed 75 percent of the project cost.

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).

Leirfossene power plant is located on the lower part of the Neavassdraget watercourse (Nidelva River) in Trondheim Municipality in Sør-Trøndelag County.
Ownership: 100 %
Production: 150 GWh
Power: 45 MW
The power plant has an installed capacity of 49 MW and an annual average production of 150 GWh. The power plant is equipped with two Francis turbines with a capacity of 29 and 16 MW.
The power plant uses a gross height of fall of 61 metres. The water is transferred by shaft and tunnel from the intake reservoir Lake Øvre Leirfoss and down to the power plant. From there the water goes through an approximately 1.5 km-long outlet tunnel that discharges downstream in Lake Nedre Leirfoss.
Leirfossene power plant was commissioned in October 2008 after two years of construction. It is built inside the mountain under the Sjetnemarka district of the municipality and replaced the Øvre Leirfoss and Nedre Leirfoss power plants from 1901 and 1910 respectively.
The two old plants were not demolished, but converted into small power plants that utilize the minimum water discharge that flows in the Nidelva riverbed parallel to the tunnel system for the new Leirfossene plant.

The Dickow SC Series are single or multistage self-priming, horizontal, side-channel pumps with end suction and vertical discharge flanges. The side-channel pump with its high differential head (achieved at low speed) has the advantage of operating more economically than standard centrifugal pumps for low capacities and high heads. The SC Series pumps are heavy duty pumps suitable for handling clean liquids without solids in chemical and petrochemical industries. The pumps are also able to prime empty suction lines after initial filling with liquid.
The maximum operating temperature for standard designs is 180°C. Special designs for higher temperatures (up to 240°C) are available on request. The maximum operating pressure is 40 bar.
To achieve low NPSH-conditions, the impeller on the suction side has an enlarged eye area. The rotating star-shaped side-channel impellers are fitted in a chamber between the suction and pressure disk and keyed to the pump shaft in floating position. No hydraulic thrust load exists.
To achieve the self-priming capability, high efficiency and rated differential pressure, there are tight clearances between the rotating impeller and the stationary disks. During priming, a stable fluid film between the impellers and the disks centres the impeller in the chamber. In applications where prolonged dry-running can be a problem, or when handling volatile liquids with low viscosities, the pumps can be fitted with additional SiC-rings to avoid contact between the rotating and stationary parts.
The suction and pressure disks are sealed to the atmosphere by confined O-rings with metal to metal fit, to prevent blow outs. In the shaft area, floating graphite impregnated PTFE-inserts are located to reduce shaft deflection and wear. The differential head is built up in the side-channel of the pressure disk.
When coupled with Ex-drive motors, the pumps can be applied in hazardous area Group II, Category 2. The pumps meet the basic safety and health requirements of Explosionproof Directive 94/9 EC and are suitable for plants with increased safety requirements.

The Grand Ethiopian Renaissance Dam project is expected to be completed by July 2017. The people and Government of Ethiopia are funding the project, which will not only serve Ethiopia, but Sudan and Egypt as well. The latter two countries depend on the Nile River for their water although 85% of the river flows in Ethiopia. The dam’s construction is expected to create up to 12,000 jobs. Approximately 20,000 people will be resettled during the course of the project.
The reservoir and dam will offer major benefits to Ethiopia, Egypt and Sudan. Egypt has for a long time held the major ownership of the water from the Nile River and prevented Ethiopia from constructing a dam. Egypt depends on the Nile for 90% of its water needs.
Aimed primarily at generating power, with an expected capacity of 6,000MW, the main and saddle dams will also create reservoirs with an impounding capacity of 74 billion cubic metres.
The dam will be capable of handling a flood of 19,370 cubic metres per second, will reduce alluvium in Sudan by 100 million cubic metres and also facilitate irrigation of around 500,000ha of new agricultural lands. It will also reduce approximately 40km of flooding in Sudan, upon its completion.
The regulated flow of water from the Renaissance dam will improve agriculture and the impact from evaporation of water from the dam will be minimal compared with other dams in Ethiopia, which will help in water conservation. Water evaporation from Aswan High Dam, as well as other dams in Ethiopia, equates to around 19 billion cubic metres. Grand Ethiopian Renaissance Dam will reduce the capacity of the Aswan High Dam, therefore saving about six billion cubic metres of water. The dam will also serve as a bridge across the Blue Nile, which features a small number of bridges and few pedestrian bridges.
The site of the dam was identified when the US Bureau of Reclamation first made a survey of the Blue Nile river between 1956 to 1964. Two site surveys were also carried out in October 2009 and between July-August 2010, with the design being submitted in November 2010.
The Government of Ethiopia kept the design phase of the project secret until one month prior to the laying of the foundation stone for the Renaissance dam project. The planning phase of the project was carried out under a name called Project X, which was later changed to Millennium Dam and finally to its present name [Grand Ethiopian Renaissance Dam].
The Grand Renaissance dam will be a roller-compacted concrete (RCC) gravity-type, comprising of two power stations, three spillways and a saddle dam. The main dam will be 145m high and 1,780m long. The reservoir, with a surface area of 1,680m2 at full supply level (FSL), will be formed in the middle section of the dam, between the left and right banks. Gated spillways fitted with six radial gates will be located on the left-side of the main dam. Each gate will have a capacity to discharge 2,450m3/s of water at probable maximum flood occurrence.
The saddle dam supporting the main dam will be 4,800m long and 45m high. It will have an emergency side spillway to discharge water directly into the Roseires reservoir. The two outdoor power stations, with installed capacities of 3,750MW and 2,250MW, will be located on either banks of the river. The power houses include 16 generating units of 375MW each. A 500kV switchyard will also be constructed to transmit power from the power stations to the grid. Approximately half of construction work was completed by December 2014. The 700MW first stage of the dam is scheduled to be operational by 2015.
Alstom signed a €250m contract with Metals & Engineering Corporation (METEC) to supply turbines, generators and all electromechanical equipment for the hydropower plant of the Grand Renaissance Dam.
Now, with the GERD operational, Ethiopia might fully electrify itself by the 2030s, without much fossil fuel in its energy mix. There’s even talk of selling power to neighboring countries—though the dam is located hundreds of kilometers from any major city, and it’s not clear if Ethiopia’s grid can handle GERD’s peak power, let alone transmit current to Sudan or Kenya.
Before any of that, the 50-billion-cubic-meter reservoir in GERD’s wake needs to fill up. Filling began in 2020, but the glass is still half full. The reservoir will need several more years before it reaches full size. As the reservoir level rises, it could eventually choke off some of the Blue Nile’s flow, shutting off the flow that joins the Nile at the Sudanese capital of Khartoum.
The third round filling of Grand Ethiopian Renaissance Dam in currently ongoing and will be finished in near few days.

Shaft power characteristics of centrifugal pumps attract extensive attentions in order to improve the operating reliability of pumps. TS-50-32-250 type low specific speed centrifugal pumps are selected as the research subjects. Three parameters of impeller including blade outlet angle β2, outlet width b2 and wrapping angle of blade θ are selected for the impeller shape optimization. Maximum flow design method and non-overload design method are adopted to design 7 impellers. Numerical simulation with CFX 12.1 is used to reduce the cost and shorten the design period. The time-averaged Navier-Stokes equations of 3D steady flow in the pump are calculated by CFX 12.1 based on the standard k-ε turbulence model together with standard wall function. The structured grids of different qualities are used in unmodified impeller for comparison to confirm that the results are not influenced by the quality of mesh.
The optimal impeller is obtained when β2, b2, θ are 18°, 7mm, 175°, respectively. The performances of NCPs at other working conditions satisfy the requirements of heads and efficiencies obtained from China National Standard. The shaft power reaches to 15 kW which is the power rating of the matched motor, at 1.45QR (35m3/h), showing that the non-overload performance of the pump is also significantly improved after modifying impeller geometries. Impeller 6 is considered as the optimal one and produced for experiments. Experiment results prove that it is effective and reliable to improve a non-overload pump’s performance by maximum flow design method and non-overload pump design method. The results provide a reference for increasing the efficiencies and heads of non-overload pumps at multiple operating conditions.


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.

An operation to retake Iraq's largest dam from Islamic State (IS) militants was launched yesterday morning, with reports suggesting that Kurdish forces are now in near complete control of the facility.
Kurdish ground forces, supported by the US through air strikes, launched the operation to seize back control of Mosul Dam on the Tigris River, which is a strategically important facility. The multi-purpose dam supplies water and electricity to northern Iraq, and there had been widely reported fears that IS militants could use the dam to flood areas downstream of the structure.
There has been confirmation that the dam has been retaken yet, but Kurdish troops are reportedly painstakingly work to clear mines from the dam area.
The Mosul earthfill dam, which was completed in 1984, is 3.4km long, 113m high and has a volume of 37.7Mm3. There is a concrete-lined gated spillway with a maximum discharge capacity of 12,400m3/sec, and a 400m long fuse-plug secondary spillway on the left abutment with a discharge capacity of 4000m3/s with levels reaching within 2m of the dam crest. The power intake structure includes four 7.0m by 10.5m hydraulically operated wheel gates.
The dam's reservoir has a total storage volume of 11.1B m3 while active storage is 8.1B m3. The hydroelectric element of the scheme includes four 187.5 MW turbines.

Technical specifications and norms for the design of hydraulic tunnels for hydroelectric power stations
The construction plans for hydraulic tunnels and underground structures for hydroelectric stations require designing on the basis of scientific investigations of the physicomechanical characteristics of rocks, carried out during excavation.
For hydraulic tunnels and underground structures of all classes the calculation of rock pressure must be carried out on the basis of scientific investigations. However, when carrying out calculations in stages of the project development rock pressure can be calculated also by well-founded equations and analogies.
When determining the wall pressure and elastic characteristics of the rock it is necessary widely to introduce contemporary leading geophysical methods of surveying, including seismic surveying.
The value of the rock pressure for spalling rocks depends on the fracturing and the dip of the strata and not on the coefficient of stability.
It is necessary to refine the coefficient a for significantly fractured rocks.

Owing to their low specific speed, regenerative pumps allow high heads with small flow rates and have performance curves with very stable features. This kind of pump is also smaller and simpler to construct than the other equivalent volumetric pumps, although it has fairly low efficiency. Over the past few years, regenerative pumps have been subject to more interest in various industrial applications. Previous mathematical models do not describe the flow characteristics very well as they are based on simplified assumptions. An improved model is proposed in this paper for the pump performance. The model can handle one inlet angle and two exit angles for the impeller blades and it can be used for the design of twisted blades that would increase the pump head and efficiency. A new feature of the pump characteristics based on the proposed model is discussed. It is shown that the proposed model yield results that are in good agreements with the experimental results. The new model also shows that the side-blade exit angle has a major effect on the performance of regenerative pump, which has not been accounted for in the previous theory.

Karwar, July 27, 2021: With the water level in Supa Dam nearing the maximum level, the people living downstream have been asked to shift to safer places and not to venture into the river.
Due to heavy rain in the catchment areas, the water level in the Kali river has been increasing in the last few days. While the maximum level of the dam is 564 meters, as on July 27 morning it had reached 550.75 meters.
If the inflow continues in the same manner, the dam is likely to reach the maximum level.
Keeping in the safety of the dam, the excess water may be let out anytime. “We request the people living downstream not to venture into the river and also shift themselves and take their cattle to safer places,” an announcement by KPCL Executive Engineer stated.
