The pipeline pump is a kind of single-suction single-stage or multi-stage centrifugal pump. It is a vertical structure. Because the inlet and outlet are on the same straight line, and the inlet and outlet are the same diameter, it looks like a section of pipeline, which can be installed at any position of the pipeline. It is called a pipeline pump (also known as a booster pump). Structural features: Single-stage single-stage centrifugal pump, the inlet and outlet are the same and on the same line, and the shaft center line is orthogonal, which is a vertical pump.
1. Test work: Check if the connecting piece is loose; use the hand to move the coupling to make the rotor turn several times, see if the unit rotates flexibly, whether there is any sound and unevenness, to determine whether there is any foreign object or shaft in the pump. Bending, the seal is not installed correctly; check whether the clean No. 20 lubricating oil in the sealed chamber is filled with 1/2 cavity space; whether the pump unit surface is clean; the unit turns to no-load test.
2, manual start: pump (first time), slightly open the outlet valve, start the motor, the pressure rises and confirms that the pump group runs smoothly when the pump valve is opened to the working condition.
3. Operation check: When the pipeline pump is in normal operation frequency, it should regularly check and record the meter readings of the pump set ammeter, voltmeter, inlet and outlet vacuum gauge, pressure gauge and flow meter, vibration, noise, temperature rise, etc. Whether it is normal or not, there should be no obvious oil leakage at the shaft seal.
4, normal parking: close the discharge valve, so that the pump light load, stop the motor.
All or part of the flow can be split from the discharge line of the pipeline pump and led to the suction port of the pump or other suitable point through the bypass pipe. One or more flow orifice plates and suitable control valves can be installed in the bypass. Metering bypass is often used to reduce the flow of boiler feed pumps, primarily to prevent overheating. If the excess flow of the bypass propeller pump is used to replace the outlet throttling, considerable power can be saved.


Blue Ridge Low Level Outlet
In 2002, the Tennessee Valley Authority awarded Atkinson a $14.8 million design-build contract for work on the Blue Ridge Dam in north Georgia. Originally constructed in 1925, this hydroelectric dam—standing 167 feet high and spanning 1,000 feet—was designed to generate electricity and reduce flood damage on the Toccoa River.
In an effort to provide the Blue Ridge Reservoir with an alternative means for regulating water elevations, Atkinson built a low-level inlet/outlet structure in the dam, which included the design and construction of a 975-foot-by-12-foot-diameter tunnel, 105-foot sheet pile cofferdam, flow control devices, and hydraulic energy dissipation systems.
During the excavation process, the team used traditional drill and blast techniques. The dam’s intake structure included the installation of a 16-foot-diameter by 50-foot steel intake liner and trashracks in the reservoir—in addition to a nine-foot-diameter by 1,000-foot steel pipe to accommodate flows of 1,800 cubic feet per second at an opening head of 130 feet. The finished steel pipe was encased in cellular concrete.
Atkinson built the intake using marine equipment. Following the completion of the intake structure, tunneling crews connected the tunnel to the intake structure.


RASUWA, April 14: The construction of civil infrastructure of the Upper Mailung Hydroelectricity Project is set to begin in a month.
Road construction work for the hydropower which is to be established in Uttargata Rural Municipality-1, has reached the final stage. Project engineer Kishor Gautam stated that the road work would finish by May 13 this year. Of the total seven kilometers of the road section to be constructed leading to the construction site, five kilometers have already been built.
For smooth completion of works, supplies are to be transported before the advent of monsoon. Contractors have already been selected for the construction process. A tunnel of 1,855-km length is to be constructed for the hydro-power plant. Civil infrastructure is set to be completed within the Nepali year 2077, and electricity will be generated within a year after that, according to the project plan. The project will have a capacity of 14.3 MW.
After the completion of the project, 79.67 gigawatt-hour electricity will be produced annually. An estimated budget of Rs 2.50 billion has been finalized for the project.
Monaliya Power Limited had initially taken responsibility of the construction. Now, however, Sanima Hydro Group is in-charge of the project. A power purchase agreement was made on September 8, 2010.
The construction company had begun work with a set target for completion on July 17, 2015. However, as construction work did not begin on the planned date, Sanima Hydro Group was handed over the responsibility.

Basic concepts for the linear model of ground water level recession
Basic concepts are illustrated for the display of ground water level recession as a linear plot on a semilog graph, as first described by Rorabaugh. This exponential decay function can be achieved if there is a definable outflow boundary such as a lake or river and if water levels are expressed relative to the altitude of the boundary. The model can be used to estimate aquifer hydraulic diffusivity. Concepts are illustrated using three finite-difference simulations. One represents the ideal case as described by Rorabaugh, in which the altitude of the outflow boundary is uniform along its length. Another simulation includes a sloping boundary with simple geometry and demonstrates that the model can be used accurately. Based on this simulation, it appears that the ground water level must be expressed relative to the closest point on the outflow boundary. The third simulation includes a sloping boundary and complex boundary shape, and demonstrates departures from the linear model of recession and errors in the estimate of hydraulic diffusivity. Another cause of nonlinearity is the instability of the ground water head profile soon after a recharge event. The nature of these early-time departures will vary depending on the location of the water level observation site relative to the outflow boundary and the hydrologic divide of the ground water flow system. ?? 2006 National Ground Water Association.

BC Hydro crews have drained Kootenay Canal in order to upgrade the canal lining at the 572.2-MW Kootenay Canal hydroelectric project in British Columbia.
The Canadian utility also reported it finished a five-year project to replace switchgear at the 1,085-MW Mica hydroelectric project on the Columbia River.
Utility crews are to line 16,500-foot-long Kootenay Canal with an extremely durable and specialized geotextile material designed for water storage in canals and reservoirs. The material is expected to extend the lifespan of the canal by about 50 years at a total cost of C$10 million (US$8.86 million).
Meanwhile, BC Hydro said it is taking steps to meet operational requirements while the project is under way. Crews are rerouting water through 51-MW Corra Linn Dam, owned by utility FortisBC, along the Kootenay River. Some water also is being stored in Kootenay Lake until it can be used when the Kootenay Canal project returns to service.
The Kootenay Canal project was built on the Lower Kootenay River in 1976 to take advantage of flow regulation by other hydro projects on the river.
BC Hydro also said it completed a project to install replacement switchgear at the 1,085-MW Mica project in British Columbia. The 500-kilovolt switchgear delivers electricity from Mica’s underground turbine-generators to above-ground transmission lines.
The project replaced 37-year-old equipment in use since Mica was built in the 1970s. New switchgear equipment also was installed to accommodate two new generating units being added as part of the 1,000-MW Mica project expansion.
In addition to ensuring reliable power, the new equipment is to improve safety and reduce greenhouse gas emissions at the facility. The work created nearly 1.5 million person-hours of employment during construction from 2009 to 2014.
BC Hydro took bids in June to replace low-voltage circuit breakers and related equipment at Mica and four other hydroelectric projects in British Columbia.

The Federal Energy Regulatory Commission on Sept. 11 said it is seeking comments – and any more permit applications – related to a Mississippi River hydro project that drew competing preliminary permit applications.
On July 23, Western Minnesota Municipal Power Agency and Lock+TM Hydro Friends Fund III LLC filed preliminary permit applications to study the feasibility of a hydropower project at the existing U.S. Army Corps of Engineers Melvin Price Lock and Dam. This dam is located on the Mississippi River near the city of Alton, Ill., in Madison County, Ill., and St. Charles County, Mo.
The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term.
Western Minnesota’s proposed Melvin Price Lock and Dam Hydroelectric Project would include: arrays of micro-turbines; a 150-foot by 150-foot substation located next to the dam on the Missouri side of the river that would step-up the project voltage from 13.8 kV to 138 kV; and a 138-kV, 1.07-miles-long transmission line connecting the project substation to an existing substation on the Illinois side of the river.
Western Minnesota has not decided on a micro-turbine supplier but states that the capacity of the project would be based on an established flow and head condition. At a mean water head of 14.7 feet and a flow of 72,600 cubic feet per second (cfs) flowing through the project, each steel structure assembly would produce 15.5 MW resulting in a project rated capacity of 93 MW. At a maximum operating head of 20.0 feet, the anticipated flow through the project would be 85,800 cfs producing 24.9 MW per steel structure assembly or 149.4 MW for the project. The estimated average annual generation would be 445.4 gigawatt-hours.
Hydro Friends’ competing Melvin Price Locks and Dam Hydroelectric Project would include: a 750-foot-long, 22-foot-wide, 66-foot-high Large Frame Module (LFM) enclosed in a powerhouse and containing 50 turbines each having a diameter of 8 feet and a nameplate capacity of 1.5 MW for a total system capacity of 75 MW; and a 69 kV or 115 kV, 4.8-miles-long transmission line connecting the project power to an existing substation. The estimated average annual generation would be 427,050 gigawatt-hours.


Abstract It is very difficult to calculate the large scale reservoir storage rapidly and accurately by the traditional calculating method of reservoir storage, and the result can't meet the request of the reservoir regulation. On the basis of the spatial information technology, this paper presents a new method of calculation of reservoir storage by gathering the precise terrain data of the reservoir and establishing reservoir watercourse DEM. From the method, the software system of reservoir storage calculation has been developed and used to calculate the static reservoir storage and dynamic reservoir storage of the Three Gorge Reservoir. The calculation results are quite accurate, which indicates that the method is feasible and can be used for the other large scale reservoirs that have the terrain DEM data.

The Minister for Housing has confirmed that €90 million is to be made available for two projects that will improve the water supply in the Greater Dublin area.
Fianna Fail's Darragh O'Brien has welcomed the funding made available for the Saggart Resevoir Project and Ballycoolen Trunk Watermain Project - both will commence in 2021.
The Saggart Resevoir Project includes the design and construction of a new 100 million litres covered treated water reservoir at the existing Saggart Waterworks to store water supplied from Ballymore Eustace Water Treatment Plant.
The Ballycoolen Trunk Watermain Project involves the design and construction of a new 9km trunk watermain providing additional pipeline capacity between the strategic storage capacity at Ballycoolen Reservoir (which stores treated water sourced from the Leixlip Water Treatment Plant) and Swords.
Minister O’Brien said: “Both of these Irish Water projects will improve the security and resilience of treated water supply to the Greater Dublin Area (GDA). Irish Water will now be able to proceed with works for both projects early in 2021 with construction expected to take over two years to complete. These projects will also contribute towards increasing the capacity to cater for residential and commercial development across the Dublin region.
"This project will improve security of supply and provide greater network resilience in the GDA. It will mean an increase in the capacity of the existing strategic network to cater for existing and future residential and commercial development and enable long term social and economic development of the wider Fingal area where I am acutely aware of the challenges which exist."

Neelum Jhelum Hydropower project inauguration planned
ISLAMABAD: As many as 96 per cent physical work on strategically important 969 MW Neelum Jhelum Hydropower Project (NJHP) has already been completed and its first unit would start supplying 242.25 MW to the national grid by February 2018.
Sources told here Sunday that the first unit would be followed by second unit in March while third and fourth units would be ready by April.
All the civil works including tunnel boring, installations of generators and turbines have been completed, they said.
The sources said completed with a cost of Rs. 404.321 billion (as per revised PC.1), 5.5 billion units of electricity annually with a cost of approximatelyRs.7 per unit and 15 years income would be spent on repayment of loans acquired to meet the cost of the project.
The project located in the vicinity of Muzaffarabad, the capital of Azad Jammu and Kashmir, is unique in its type in the country and was a difficult one as its all infrastructure including dam, water channels and power house is under ground and the river Neelum has been diverted 19.6 kilometers long underground tunnels.
The River Neelum has been diverted at Nauseri, 41 kilometers of here while the power house has been constructed at Chatter Kalas, 22 kilometers south of the city and after passing through turbines, water has been released in the river 4 kilometers further away from the site through another tunnel.
The composite gravity dam, 160 meters long, and 60 meter high, has been constructed underground at intake point Nauseri having the capacity to store 10 million cubic feet water with peaking reservoir of 3.8 million cubic feet to meet daily peaking requirements.
They said that water filling has been started in last week in the reservoir subsequent to the substantial completion of the dam.
Total storage of the dam is 8,207 acre feet upto design reservoir operating level of 1015 meter above mean sea level. After successful filling of the reservoir, the water would be diverted into the water way system by the end of 2017.
On completion, the project would contribute about five billion units of electricity to the national grid annually and annual revenue of the project was estimated to be Rs 50 billion, they said.
The project is an engineering marvel with 90 percent of the project being underground in the high mountain areas. The project consists of four units with installed capacity of 242.25 MW each.

Steel Bayou Channel Repair Progresses
The U. S. Army Corps of Engineers Vicksburg District’s work on the Steel Bayou Drainage Structure Outlet Channel Repair Project near the Mississippi Highway 465 bridge is approximately 88 percent complete.
Work was delayed because the contractor was unable to move upstream of Highway 465 to complete rock work due to high stages on the Mississippi River. Remaining efforts include stone placement upstream of the bridge and around top bank of the bridge and additional bank paving downstream.
Approximately 200,000 tons of rock have been placed to date with 25,000 tons remaining to be placed. Work resumed on November 1, 2014.
The work was necessary to repair a scour hole that developed downstream of the bridge. The project is expected to be completed by the end of November 2014.
During the construction of the project, there will be no boating or fishing along the channel from the Steel Bayou Control Structure to the Yazoo River.

Sarawak Energy Berhad (SEB) is studying a plan to reroute a 275 kV transmission line, currently being built to channel electricity generated by the RM3 Billion Murum Hydro Dam to the Sarawak Coridor of Renewable Energy (SCORE), to facilate the construction of another dam in Balepeh.
The letter, located in the upper reaches of the Balui River where the 944 MW Murum Dam is being built, can generate 110 MW. The RM100 Million transmission line, originally scheduled for completion in the third quarter of 2012 - a year ahead of the first power to be commercially produced by the Murum Dam, would connect the latter to the transmission system near Bakun.
The Murum Dam Project, which was 44 % completed, is located about 60 km upstream of the Bakun Dam. SEB also identified other hydro dam projects upsream of the Balui River, namely Linau (290 MW) and Danun (200 MW). Undertaken by Three Gorges Development Corp (M) under a single contract with SEB, the Murum Dam comprises several key components namely, a 145m high roller-compacted concrete dam, intake and 2.7 km long tunnels supplying water to a 944 MW power house.
The Murum Dam is a key part of the SCOPE project and would be the next major hydro generation project to be commissioned after the Bakun Dam. Murum electricity power is slated to come in time to take up power demand from SCORE industries which the Bakun Dam is unable to meet.

Bakun expected to be operational by 2010 will start transmitting electricity too Peninsular Malaysia by 2013
The Bakun hydro-electricity dam project, about 180km from here, will start to transmit power to Peninsular Malaysia by 2013, said Deputy Minister of Energy, Water and Communications Datuk Joseph Salang Gandum.
Salang, who visited the project over the weekend, told reporters here the RM3.2 billion project was expected to be operational by 2010.
About 100 megawatt (MW) to the state grid through the Similajau HVDC (high voltage direct current) lines which would be ready by next year.
By 2013 it is expected to begin transmitting 1,600MW to Peninsular Malaysia via the 676-km submarine cables across the South China Sea. The project would initially operate with three of its eight turbine generators, each with 300MW capacity, and would use the rest as more water was available in the reservoir area. The 695 sq km reservoir is almost as big as Singapore. It provided sustainable energy source. The 205-metre Bakun dam would be the second highest rockfill dam in the world after the Shibuya dam in China.
Civil works for its wall, spillway (to flush out excess water), power intake, power tunnels and powerhouse were expected to be completed by June 2010.
The process of draining water into the dam is expected to begin on Nov 21 this year. The dam will be filled in 18 months
Bakun will be the most beautiful dam. It will have six islands and will offer immense eco-tourism potentials.


BOISE, Idaho — The Boise River is running dangerously high, swift and cold and starting Tuesday, it will be even higher. The U.S. Army Corps of Engineers announced it will be increasing river flows through the City of Boise beginning Tuesday, in order to help reduce the risk of flooding later in the spring.
There are signs around the river reminding the public that dangerous river conditions are currently in effect, and that anyone who gets into the water and has to be rescued will be fined the cost of the rescue efforts, under city code.

The speeding up of the project approval is imperative for work to be completed before NE monsoon next year
The project to build a channel to divert a portion of surplus water from Somangalam-Adyar confluence point to downstream stretch of the river awaits the State government’s nod. This is set to alleviate flooding in some southern suburbs.
This northeast monsoon, the Adyar carried a peak flow of 20,000 cusecs in its upper reaches. As the maximum flood level of the river is higher by a minimum of four feet, it led to issues in draining floodwater into the waterway.
The project had been submitted to the government through Commisionerate of Revenue Administration and Disaster Management. The speeding up of the project approval is imperative for the work to be completed before the northeast monsoon next year, the officials say.
Moreover, the river is only about 20 metres wide at some points due to urbanisation. The Water Resources Department (WRD) had chalked out a ₹70.05-crore project to mitigate inundation in areas such as Ashtalakshmi Nagar, Mudichur and Mahalakshmi Nagar. This is one of the many solutions proposed to prevent floods in these suburbs.
The officials said surplus water of tanks upstream such as Manimangalam and Orathur tributary drain nearly 15,000 cusecs into the Adyar river near Vandalur Wallajahbad Road. Another 5,000 cusecs of water joins the river downstream at Somangalam tributary confluence point. As the culvert capacity is insufficient near Outer Ring Road, surplus water spills over to the neighbouring areas, including Mudichur.
“We have planned to build a channel from the confluence point of Somangalam tributary-Adyar river to convey excess water for two km and linked to the river again after the outer ring road where there is more width available. The channel will carry about 850 cusecs of water. There is no land acquisition required for the project,” said an official.
A major share of the project cost is proposed to be spent on constructing flood protection walls in vulnerable stretches between Adanur and Tiruneermalai. The retaining wall with lining would prevent breaches in the river and reduce waterlogging in the neighbourhood.

Flood release structures of high-head dams generate high-velocity plunging jets. These may scour the downstream rocky riverbed and even damage the dam foundation. Assessment of the scour evolution is essential to ensure the safety of the dam and appurtenant structures, as well as to guarantee the stability of its abutments.In the framework of a research project, near-prototype scaled experimental installation generating high-velocity jet impact in a plunge pool has been equipped with an artificial rock block. Pressure fluctuations over and under the block as well corresponding block movements are recorded for a jet impacting at the block upper face. The jet impact is situated along one of the block side faces, resulting in asymmetrical jet impact conditions. The analysis focuses on the reponse of the block due to the water pressures acting above the block and inside the fissures surrounding for both core and developed jets.

Until recently the measurements on the dam Jez Podselo were made only on the upper water level. With the new approach of water energy management is to attain complete overview of the movement of the water level flowing into the lake with the lake tributaries.
With the new system the upper and the lower water level on the dam Jez Podselo are measured, as well as of the two tributaries on the measuring points Most na Soči and Bača pri Modreju.
V-elin manufactured hydrostatic probes are used on all measuring points. The probes on the upper and lower water level are wire connected with the computational unit through the unit for galvanic isolation.
The probes are connected to the central computational unit that enables local display of measured values (levels and water temperature), which is connected to the central SCADA power plant system through the RS485 Modbus communication. This connection is established with the optical communication. Central computational unit is manufactured by V-elin, and SCADA power plant system is manufactured by SIEMENS.
Central computational unit is equipped with GSM/GPRS communication modem with which it can collect data measured on the remote measuring points at Most na Soči and Bača pri Modreju.
Measuring points at Most na Soči and Bača pri Modreju have their own power supply through PV modules, batteries for periods without sun and a computational unit that ensures the operating of the whole system as well as the continued transfer of measuring signal to the central computational unit.


The basic structure of the self-priming pump is composed of six parts: the impeller, the pump body, the pump shaft, the bearing, the sealing ring and the stuffing box. They act as different roles.
1. The impeller is the center of the centrifugal pump. It has a relatively high rotational speed and a large output. The blade on the impeller plays the primary role. The impeller is subjected to static balance test before the device. The surface of the impeller is lubricated to reduce the conflict of water flow.
2. The pump body is also called the pump casing, which is the main body of the self-priming centrifugal pump. It supports the fixing effect and is connected to the bracket of the device bearing.
3. The effect of the pump shaft is that the coupling is connected to the motor and the torque of the motor is transmitted to the impeller, so it is the primary component for transmitting mechanical energy.
4. The bearing is a member that supports the pump shaft on the pump shaft, and has two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant to refuel properly. Usually 2/3~3/4 of the volume will heat too much, too little and there will be noise and heat! The sliding bearing uses the bright oil as the lubricant, refueling to the oil level line.
5. the seal ring is also known as the leak reduction ring. The empty space between the impeller inlet and the pump casing is too large to form the water in the high pressure zone of the pump flowing to the low pressure zone through the empty space, affecting the water output of the pump, and the power is reduced! If the empty space is too small, the impeller and the pump casing will collide and wear. In order to reduce the leakage resistance by adding the backflow resistance, the service life of the impeller and the pump casing is postponed. The sealing ring is installed at the inner edge of the pump casing and the external contact of the impeller, and the sealed open space is preferably between 0.25 and 1.10 mm.
6. The stuffing box is mainly composed of packing, water sealing ring, packing tube, packing gland and water sealing tube. The effect of the stuffing box is primarily to close the open space between the pump casing and the pump shaft, so that the water flow in the pump does not flow to the outside and the outside air does not enter the pump.
Self-priming pump selection principle:
1. Note that the type and performance of the selected pump meet the requirements of process parameters such as flow, head, pressure, temperature, cavitation flow, and suction.
2. must meet the requirements of the media characteristics.
For pumps that transport flammable, explosive, toxic or valuable media, shaft seals are required to be reliable or leak-free pumps, such as magnetic drive pumps, diaphragm pumps, and shield pumps; for pumps that transport corrosive media, corrosion resistance is required for convection components. Materials, such as AFB stainless steel corrosion-resistant pumps, CQF engineering plastic magnetic drive pumps; for the transport of pumps containing solid particulate media, the convection components are required to use wear-resistant materials, if necessary, the shaft seals are washed with a clean liquid.
3. High mechanical reliability, low noise and low vibration.
4. The overall cost of equipment, operating, maintenance and management fees should be considered economically.
5. The centrifugal pump has the characteristics of high speed, small volume, light weight, high efficiency, large flow, simple structure, no pulsation of infusion, stable performance, easy operation and convenient maintenance.

Large scale infrastructure global construction and engineering group, Webuild, has commenced pouring concrete for the core of the world’s tallest and highest dam.
Formerly known as Salini Impreglio and still headquartered in Italy, Webuild is responsible for the main civil works in the construction of the Rogun dam in the upper reaches of the Bakhsh River in the Pamir Mountains west of the Himalayas in Tajikistan.
The structure, which is expected to be complete by 2028, is located 90 km from the country’s capital, Dushanbe. It will be the highest dam in the world, at 1300 metres above sea level, breaking the record held by Nurek Dam, which is up-river. Rogun will be rock filled with a loam core.
Not only will it be the highest dam on the planet, it will be the tallest, at 335 metres above the canyon floor, with a crest length of 660 metres. It forms part of the 3.6GW Rogun hydropower project which includes tunnel works and construction of the powerhouse and electromechanical works and has 2000 people working on it.
Webuild revealed the Rogun dam already has two turbines producing electricity, each with a capacity of 600MW, allowing Tajikistan to reduce power shortages and export electricity. Once all six turbines are installed, the dam will have a total capacity of three nuclear power plants, making it the most power hydroelectric station in Central Asia, the company said.
Webuild started work on the project as Salini Impreglio in 2016. The company is very active in Australia and is working on Australia’s Snowy 2.0 project and has projects country-wide such as Melbourne’s North East Link, Perth’s Forrestfield-Airport Link, and Inland Rail.

Another world-class hydroelectric power station, second in size only to the mammoth Three Gorges Power Project, will be built on the middle reaches of the Lancang River.
Construction of the Xiaowan Hydroelectric Power Station will start this year, Yunnan Provincial Governor Li Jiating announced recently.
The new power plant will be the third large power project on the Lancang River, after the 1.5-million-kw one at Manwan and the 1.35-million-kw one at Dachaoshan.
It will have six generating units with a designed capacity of 4.2 million kilowatts.
The major feature of the station will be a 292-meter-high concrete hyperbolic arch dam, which is equivalent to the height of a 100-story skyscraper.
The dam, believed to be the highest dam in the world, will be able to hold 15 billion cubic meters of water, the combined amount of all reservoirs in Yunnan, said Kou Wei, general manager of the Lancang River Water Resources Development Co., Ltd.
Lancang River, which rises in the Tanggula Mountains on the Qinghai-Tibet Plateau, flows for a total of 4,500 kilometers from Tibet to Xishuang Banna in Yunnan Province, joins the Mekong River, and then flows into Laos, Myanmar, Thailand, Vietnam and other countries.
Six hydroelectric power stations will be built on the middle and lower reaches of the Lancang River this year. The installed capacity of the eight power stations will be 15.55 million kilowatts.
The cost of the Xiaowan power station is estimated at 32 billion yuan (US$3.85 billion), the largest sum spent on a project of this kind in Yunnan in the past 50 years.
Tens of thousands of workers will be needed to build roads, bridges and other auxiliary projects to support the project, Xinhua said.


Dredging Under Way at Shark River Inlet
Army Corps project will deepen channel, address shoaling
The Army Corps of Engineers is performing routine dredging at the mouth of the Shark River Inlet, a project manager confirmed.
Edward Wrocenski, who is managing the dredging project, explained that due to shoaling issues between the jetties separating Avon-by-the-Sea and Belmar, pumping is required to keep the inlet open to marine traffic.
"The sand gets trapped there," Wrocenski explained, noting that the channel will eventually be deepened to 18 feet.
The dredge ship Currituck, which has previously been doing similar work on the Manasquan Inlet, arrived Saturday night. The project is expected to last 10 or 11 days.

It is an accepted fact that quite a number of problems faced in a pumping station are related to the design of sump or intake rather than pump design. Head-capacity curves provided by the pump manufacturer are obtained on the condition of no vortices flowing into the pump intake. The efficiency and performance of pumping stations depend not only on the performance of the selected pumps but also on the proper design of the intake sumps. A faulty design of pump sump can lead to the occurrence of swirl and vortices, which reduce the pump performance and induce vibration and additional noise. Therefore, sump model test is necessary to check the flow condition around intake structure. Numerical simulation is a good facility for reducing the time and cost involved throughout the design process. In this study, the commercial software ANSYS CFX-13.0 has been used for the CFD analysis of the sump models.
In a scaled sump model for air entrainment simulation, numerical analysis of single phase and two-phase with SST turbulence model was carried out to predict vortex (both free surface vortex and submerged vortex) occurrence and location. The effectiveness of curtain walls and square bars to eliminate the free surface vortex is evaluated. Meanwhile, the experiment including PIV system was performed in KMOU to investigate the flow conditions around pump intake structure.
In a full size sump model, overall numerical analysis for the sump model with a mixed flow pump installed was carried out. Hydraulic performances of the mixed flow pump for head rise, shaft power, pump efficiencies versus flow rate changed from 50% to 140% of the design flow rate were studied by the performance curves. A trident shaped anti vortex device (AVD) composed of three wall fillets and one center splitter was installed under the pump intake. The effectiveness of the AVD for the suppression of submerged vortex was evaluated. In addition, numerical simulation of cavitation phenomenon in the mixed flow pump has been performed by calculating the full cavitation model with k-ε turbulence model.
According to the results, details of the location, size and strength of vortices were predicted in the numerical simulation. For the scaled sump model, although there is a little difference between the single phase and two-phase simulation, all the results predict the free surface vortex and submerged vortex formation and location. The CFD simulations of flow condition show good agreement with the PIV results. The effectiveness of curtain walls installed to inhibit the free surface vortex is confirmed in the CFD results while the square bars installed in the channel failed to suppress the free surface vortex. For the mixed flow pump with sump, the best efficiency point (BEP) is at the design flow rate with the corresponding efficiency of 89.6%. The effectiveness of AVDs installed for the submerged vortex is confirmed by comparisons of the sump model with and without AVD results.
Cavitation phenomenon analysis shows the pump operating at the BEP condition has a considerable extent over the requirement of cavitation performance. With numerical simulation, the inception of cavitation in the blade passage is observed on the suction surface where the leading edges meet the tips, and then as the inlet total pressure decrease, the cavitation zone is spread out over the suction surface as well as the leading edge of the impeller blade.
