We investigated the hydraulic design and flow field in a multi-stage pump to achieve high efficiency and low cavitation performance using computational fluid dynamics (CFD) and experimental approaches. The subject of the investigation is a four-stage centrifugal pump, which consists of a suction bend, impellers, stators, and a discharge volute. In designing a high performance multi-stage pump, it is important to investigate the interaction of flows between the stator and impeller, which were also investigated individually for minimizing hydraulic loss. The flow field in the suction bend, therefore, was simulated first using conventional CFD based on the Reynolds-Averaged Navier-Stokes (RANS) equations, and the calculated result of the flow field at the outlet of the suction bend was used to design the impeller inlet shape at the design-flow rate. To obtain a high-performance impeller shape, the effect of the meridional configuration of the impeller on hydraulic loss was examined using a parameter design based on conventional CFD results. The meridional shape was composed of several design parameters such as inlet, outlet diameter and so on, and a few parameters, which contribute to reducing hydraulic loss significantly, were extracted using the parameter design. Therefore, we obtained a highly efficient impeller shape by adjusting those important parameters. Finally, to evaluate and confirm the interaction of the flows between the stators and impeller, a numerical calculation of the four-stage pump was carried out using advanced large eddy simulation (LES). As a result, we obtained the predicted flow field in the four-stage pump. There was no significant flow separation at the inlet of each impeller and it was confirmed that the blade design was appropriate. The hydraulic performance of the four-stage pump was also confirmed using a model pump test. The inception of cavitation was observed and the cavitation coefficient estimated using experimental results was in good agreement with the CFD prediction. As a result of this development including the investigation described above, the hydraulic shape of a highly efficient and high-cavitation performing four-stage pump was obtained.

Landustrie model BSP
In practice, pumping solid parts with a small centrifugal pump usually leads to blockage. It is then soon opted for a too large inefficient pump. The engineering at Landustrie has thought about this and the cutting mechanism of the DSP submersible pump has been mounted together with the impeller and an e-motor. In this way it is possible to transport large components with relatively high pressures. This pumptype can be used as a normal centrifugal pump, with the the advantage to pump particals.

Improved flooded area/power ratio
The River Madeira has a flow of 4,000 m³ per second during the dry period and 45,000 m³ per second in the rainy period. For this reason, the kind of turbine for the operation is the bulb type which is more suitable to the conditions of this river, with large volumes and water speed and reduces the need for large reservoirs. The flooded areas will be practically the same size as those which occur during the annual flooding of the river.
The Santo Antônio HEP has the best ratio between the flooded area and the installed capacity of all the hydroelectric plants in the Amazon plain region. The plant´s reservoir will measure 271 km². When the area of the natural flood is dammed, the area of the reservoir comes to 110 km².

This master's thesis deals with an experimental research of the intake flow conditions on cooling towers pumping system in the Nuclear Power Plant in Krško. Formation of the free surface vortex type 6 in the pump sump was not acceptable for the operation of the CT1 pump and the cooling system in general. Detailed flow conditions in the intake structure were needed. Field measurements as well as a design of the physical hydraulic model with a scale factor 16 were conducted in the laboratory. Pumping systems, intake structures and centrifugal pumps are described in the theoretical part of this paper. This section provides a theoretical background in describing the flow through conservation laws pumping systems, free surface flow, dimensional analysis, with an emphasis on free surface flow and measurement uncertainty. The chapter is followed by an overview of research dealing with the issues of intake structures. The empirical approach and recommendations of Standard ANSI/HI for pump intake design and for designing a physical hydraulic model are introduced. At the end of the theoretical part, measurement techniques and measuring procedures are included as well. The following experimental sections presents an example of the analysis of a CT pumping station, providing field measurements and model tests in the laboratory. The model tests were made for different operational conditions of pumps. Comparison between the model and the prototype showed a good agreement with the formation of identical free surface vortex type 6 in the same area of the sump. In order to prevent the formations of an unfavorable free surface vortex, the geometry of intake structures with the additional elements and obstacles were modified. The model test which included an installation of an extended intermediate wall provided favorable flow conditions in the acceptable criteria of Standard ANSI/HI.

Optimal Control of Large Flood of Ankang Reservoir
Located in the upper stream of the Hanjiang River, the Ankang Reservoir is a large hydro-junction mainly for electric power generation as well as for flood prevention and shipping. Rainstorms in the Hanjiang River in summer have high occurrence with concentrated floods characterized by sudden surge and sudden fall. Considering staggering the Hanjiang River and the Yuehe River flood peaks, on the premise of ensuring the dam safety and meeting the flood prevention requirements of Ankang Town, this Thesis establishes the mathematical model for the Ankang Reservoir large flood multi-objective optimal deployment, adopts the progressive optimality algorithm (POA) to solve the model to work out the optimal control with the inconsistent objectives of flood prevention and power generation during large flood and gives examples. The result shows that the mathematical model is workable and practicable and the solution methods are rapid and accurate.

**MEDIA ADVISORY** Congressman Pallone to Visit Shark River Inlet Dredging Project
BELMAR, NJ – Today, Monday, June 25, Congressman Frank Pallone, Jr. (NJ-06) will visit the Shark River Inlet to highlight maintenance dredging that began there on June 20. The dredging is conducted by the Army Corps of Engineers to improve the safety and accessibility of the inlet. Funding for this project was included in the Fiscal Year 2012 budget at Congressman Pallone’s request.
Two areas of the Shark River Inlet are frequently affected by shoaling, which is when sediment builds up at the bottom of the river. During this dredging operation the Army Corps of Engineers will remove approximately 30,000 cubic yards of sand so it will be deep enough that boats will be able to safely utilize the inlet.
Congressman Pallone will be joined at the event by local officials, and representatives from the Army Corps of Engineers and the Recreational Fishing Alliance.

Home » Shop » 2008 – Risk assessment in spillway remedial works design and construction and monitoring at Googong Dam
James Willey, Malcolm Barker, Javad Tabatabaei
Abstract: During successive flood events from the end of construction of Googong Dam in 1978 through to the late 1980s, erosion of in excess of 5,000 m³ of rock occurred in the partially unlined section at the downstream end of the spillway channel. Remedial works were undertaken in stages during the 1980s to stabilise the eroded chute and limit further erosion. A project is currently underway as part of the Bulk Water Alliance to construct remedial works in the spillway to repair erosion damage and increase the spillway capacity to safely pass the current estimate of the Probable Maximum Flood. The design was undertaken by GHD Pty Ltd as part of a separate engagement prior to the formation of the Alliance.
The recent work involved a review of the historical performance and prediction of future performance of the structure. A process involving the development and comparison of options and ultimately the detailed design of the preferred arrangement followed, including refinement and validation using a physical hydraulic model study.
This paper presents risk assessment techniques used throughout the project on a range of tasks including prediction of future spillway erosion damage and comparison of spillway remedial works options, assessment of construction flood risk and definition of instrumentation requirements for the dam and associated structures.
Keywords: risk assessment, remedial works, spillway erosion, rock erosion, construction risk, instrumentation.

Model Studies of the Portugues and Bucana Rivers Channelization, Puerto Rico. Hydraulic Model Investigation.
Final rept. Mar-Nov 75,
ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MISS
Pagination or Media Count:
Two 130-scale physical hydraulic models of the Portugues and Bucana Rivers were used to determine the adequacy of the original designs for the flood control channelization project through the city of Ponce, Puerto Rico. The proposed channelization included trapezoidal to rectangular channel transitions, stilling basins, and drop structures in the high-velocity channels. A 3300-ft prototype channel length was used to study the transitions and stilling basins including riprap stability downstream from the stilling basins. A 1200-ft prototype channel length was used to study the drop structures and the adjacent riprap protection requirements. Test results indicated that the original design with certain modifications would effectively transmit all expected flood releases from the proposed Portugues and Cerrillos Dams. Modifications to transitions at entrances to the high-velocity channel reaches were streamlined within the original right-of-way to reduce surface turbulence and standing waves. Geometry of the original stilling basins was altered to prevent the oblique hydraulic jumps and the end-sill heights were lowered to reduce the water-surface drawdown, surface roller waves, and high bottom velocities downstream of each basin.

The Zimbabwe National Water Authority (ZINWA) is set to undertake an expansion project on key aspects of the Victoria Falls water supply system
The proposed project coincides with the forthcoming UNWTO conference, which is set to be held in August 2013.
As part of Zimbabwe's preparations to successfully co-host the UNWTO conference, the project is expected to offer long-term value to the Victoria Falls water supply system.
"As council, we discussed the issue of raising water capacity and a new water station was suggested,” said Victoria Falls mayor, Nkosilathi Jiyane.
According to a ZINWA planning manager, the expansion plans will include deepening the existing raw water abstraction channel in the banks of the Zambezi River.
Plans will also be underway for the construction of a new pump station at the Zambezi and booster pump-stations, while the pumping capacity will be upgraded from the current 900 cu/m per hour to 1,500 cu/m per hour.
"Council has since agreed to go-ahead with the project. We are confident that the project would be complete before the UNWTO meeting. But the pump station would be used long after the event is over," added Jiyane.
“Currently, we are planning on a population of 750,000 people and it might grow hence the need of a new pump station.”

1.Introduction to QDX Small Submersible Pumps:
The QDX small submersible pump consists of pump, seal and electric motor. The electric motor is located in the upper part of the electric pump and is a single-phase or three-phase asynchronous motor. The pump is located in the lower part of the electric pump and is a centrifugal impeller and volute structure，between the pump and electric motor. The double-end mechanical seal is adopted, and the “O”-shaped oil-resistant rubber seals are used as static seals at each fixed stop. The clear water submersible pump shaft is hard chrome-plated, which effectively improves the wear resistance and corrosion resistance of the shaft and facilitates the maintenance and disassembly of the impeller. The motor is equipped with a thermal protector, which can disconnect the power protection motor by itself in case of lack of phase, overload, and overheating of the motor.

It is very important to identify the reverse loss coefficient of BWR jet pump in the evaluation of core inlet flow at the beginning phase of BWR LBLOCA (Large Break Loss-of-Coolant Accident) analyses. Hence, the reverse flow property of jet pump was investigated in relation between the momentum equation, pressure loss coefficient and RELAP4 noding, and a new modeling has been proposed. In the proposed modeling, an equivalent pressure loss coefficient is used to take into account of the effect of accellerating pressure loss by the continuous flow area reduction from the tale pipe to the throat. The effectiveness of this model was studied by analyses for the LOFT 1/6 scale jet pump experiment and typical BWR LBLOCA. It has been, consequently, shown that this proposed model gives better jet pump property than a previous model which is used in the WREM sample problem and which gives very conservative result in core inlet flow and in the peak cladding temperature through whole transient.

Foot Valve X9121
DESCRIPTION: Foot Valve (Baffle Type Cartridge)
Concept of foot valve
The foot valve is also called a check valve. It is a low-pressure flat valve. Its function is to ensure the one-way flow of the liquid in the suction pipe and make the pump work normally. When the pump stops working intermittently for a short time, the liquid cannot return to the water source tank to ensure The suction pipe is filled with liquid to facilitate the start of the pump.
The foot valve is divided into:spring foot valve,pump foot valve,water pump foot valve：
The foot valve is equipped with multiple water inlets on the valve cover and equipped with a screen to reduce the inflow of debris and reduce the probability of clogging of the foot valve. Although the foot valve is equipped with an anti-clogging screen, the foot valve is generally suitable for cleaning media, and the foot valve is not suitable for media with excessive viscosity and particles.

2D River Modelling with Usace HEC_RAS 5.0.7: Simulation for Operation, Flood Events and Dam Breaks
12 November, 2020 | White paper
The practice of 2-dimensional river modelling has been conducted in the industry for almost 30 years. In the beginning, the application was very expensive and complicated due to technological limitations. Over the years, as both computer technologies and modelling theories have evolved, design engineers are able to create 2D river models using regular office computers with specialized software.
A 2D river model can be used in numerous applications such as infrastructure planning, dam safety study and flood scenario prediction. It has several advantages compared to the conventional 1D model in terms of accuracy and workability. Furthermore, georeferenced 2D models can produce better visual results, which makes it easier for designers to communicate with nontechnical stakeholders and integrate as part of emergency planning exercises.


A finite difference model that simulates freshwater and saltwater flow separated by a sharp interface has been applied to estimate the salinity intrusion in the lower part of the Walawe River basin to the southern coastal aquifer, Sri Lanka. The effect of hydrogeological factors on the dynamics of the freshwater-saltwater interface has been considered through storage coefficients, porosity and hydraulic conductivity. The paper concludes that hydraulic conductivity is the main hydrogeological factor affecting the movement of the freshwater-saltwater interface, and the saltwater intrusion is more sensitive to groundwater recharge than hydrogeological properties. Therefore, the model was calibrated by adjusting the hydraulic conductivity to match the observed salinity profile in the southern coastal aquifer. Simulation results compare well with the observed long-term salinity profile suggesting that the numerical model can be used to successfully simulate the salinity profile in the area.
