Market Weighton flood defence scheme under way
A multi-million pound scheme to improve flood defences in an East Yorkshire town has begun.
The Environment Agency said the £3m project would reinforce safety at Mill Beck, upstream of Market Weighton town centre, protecting properties.
The beck flows into the town through an area known as Monkey Run where a disused railway embankment helps contain water after heavy rain.
Agency officials said the project would help ensure the embankment's stability.
A new concrete spillway is being built to convey water from behind the embankment, returning it in a controlled flow to the beck further downstream.
The work is expected to take seven months to complete.

China to build hydropower plant on Brahmaputra river: Neighbouring countries enragedtext_fields
Chinese government's plan to build a hydropower plant on the Brahmaputra river has enraged its neighbouring countries, Bangladesh and India.
The proposal has been put forward in its 14th five-year plan, which will be implemented by next year. The official media on Sunday quoted the head of a Chinese company tasked to build the dam. The plan is expected to be officially approved by the ruling Communist Party of China (CPC) by next year.
China has already built small dams in the river. The new project will be built in the Medog region. This region lays close to India's Arunachal Pradesh. China claims that the dam will be effective for its border security.
The proposed dam is expected to generate power three times more than the three famous dams in the country. This new move of the Chinese government has evoked concerns in India and Bangladesh.

Farmers of Mahe, Seychelles’ main island, will benefit from the increased water supply from a proposed water reservoir in Bon Espoir. Once the agriculture department finalizes the project farmers are expected to improve their agri-business.
As part of the project, a gabion will be erected to collect and store 1,000 cubic metres of water. A gabion is usually a cage filled with rocks, used to construct walls to contain soil and water. When used to seize water, gabions also serve as filtering dams. Additionally, gabions not only increase water storage capacity but also harness the resource.
Also Read: Seychelles: Grand Anse Mahe dam feasibility study & design enters final stage
Instead of letting the water flow down to the sea, the new water reservoir in Bon Espoir will provide an alternative water catchment facility. The gabion is becoming a popular system for harvesting water. It is a long-term project that is strong and durable.
Benefits of gabions in the construction of the new water reservoir in Bon Espoir
Before work on the project begins, farmers who are already getting their water in the area will have to relocate. Additionally, the new relocating area has been identified by the agriculture department. This will avert the water supply from having a high content of the soil. Importantly, failure to relocate the local farmers and remain connected to the wetland during construction, water supply will be contaminated.
The construction of the new water reservoir in Bon Espoir will take 6 months to complete. A similar project is to be undertaken on Praslin to handle water supply hitches on the second-largest island of Seychelles. Using gabion for water harvesting in national projects piloted in 2018 at the Bougainville.
Following the project in the wetland in the district of Takamaka in the south of Mahe, two more such reservoirs were built at Val D’en Dor and Baie Lazare. Such reservoirs increase resilience to climate change and benefit the water supply for human consumption, food security and livelihood. Such projects provide an alternative to desalination for potable water invention and the sustainability of the environment.

The construction work at the Montafon Rellswerk in Vorarlberg has already been completed. © Nägele Structural and Civil Engineering
After extensive planning work, construction work on the Rellswerk 2014 was able to begin by Vorarlberger Illwerke AG. The aim is to generate electricity exclusively from hydropower and other renewable energies. The gradient of the upper Rellsbach can now be optimally used for the Lünerseewerk.
The main function of the Rellswerk is to supply water from the inlets of the upper Rellsbach stream to the drive water system of the Lünerseewerk.
This is intended to increase the water resources of the Lünerseewerk. The water from the inlets is temporarily stored in an equalizing reservoir, pumped via a pressure pipe into the Lünersee-Latschau water channel and pumped further into the Lünersee. Around 17 million cubic metres are pumped into the lake every year.
A reservoir was built for the new Rellswerk. ARGE Rellswerk Vandans, which includes the PORR subsidiary Nägele Hoch- und Tiefbau GmbH, was commissioned with the construction work on this compensating reservoir. The compensating reservoir has a utilisation volume of 44,000 m3 . The shaping of the basin and the design of the bank areas were implemented very close to nature.
In the course of the construction work, the Rellsbach was diverted and now runs along the foot of the dam. The maximum static dam height is about 14 m.
The construction of the nacelle, which was to be integrated into the upper section of the artificial dam, was even more complex than the construction of the equalizing reservoir. After completion of the building, only the access portal is visible from the outside. According to the wishes of the operators, the entire plant should remain as undetectable as possible. The majority of the hydropower technology is located underground.
The plant is not accessible in winter and therefore runs completely without any maintenance.

The Mashel River project originated with a long term vision and watershed restoration plan in the early 2000’s. The project is primarily based on the Nisqually River Chinook recovery planning efforts and outlines priority restoration reaches within the river corridor for large wood placement. The plan later was adapted to benefit multiple species.
The first construction project was completed in 2005 and subsequent reaches were completed over the next 13 years. In total, over 60 log jams were constructed.
The purpose of the jams is to improve spawning, flood refuge, channel roughness, and to re-connect side channels for salmonid rearing in the watershed. The Mashel River also has extremely low summer flows and these jams help create deeper cool pools.
SPSSEG has been involved in this project since 2002 and implemented many of the projects identified in the watershed restoration plan.

Duke Energy Carolinas LLC said it plans to build a new powerhouse to replace 18-MW Bridgewater powerhouse as part of a seismic remediation project planned for Linville Dam in North Carolina and South Carolina.
Remediation of Linville Dam requires removal of Bridgewater powerhouse and construction of a 26.4-MW replacement powerhouse before dam remediation can begin. Linville is one of three large earth dams in the Bridgewater development of the 814-MW Catawba-Wateree hydroelectric project (No. 2232).
Remediation calls for a compacted earthfill stability berm to be constructed on the downstream portion of the 160-foot-tall, 1,325-foot-long embankment dam. The new powerhouse would be built outside the footprint of the dam remediation project, about 200 feet downstream of the existing powerhouse at the toe of the dam.
Duke announced the signing of a relicensing agreement for the Catawba-Wateree project in August 2006. (HNN 8/17/06) Modifications to allow the flow releases to meet relicensing requirements were discussed over a three-year period among participants in the relicensing process.
Duke settled on building a new powerhouse after considering whether to replace the existing 18-MW powerhouse with a new powerhouse or to install a valve system as a means of releasing flows from the reservoir.
Duke’s request to replace the powerhouse is pending before the Federal Energy Regulatory Commission. If the new powerhouse proves infeasible, Duke would implement the system of large valves at the same location as an alternative means of releasing flows.

Computational fluid dynamics (CFD) is widely used to simulate fluid flows in turbomachinery. A detailed CFD study was performed to enhance the design of an electrical submersible pump (ESP) manufactured by Baker Hughes. The pump has a special patented impeller design enabling it to handle up to 70% gas volume fraction (GVF).
A CFD-based design study was performed on the ESP diffuser (for the first time) to improve the pump’s performance and reduce losses. The CFD model was initially validated using experimental results. Different designs were simulated to reach the optimum design. Many factors affect pump performance, including flow separation losses in the stator (such as the number of blades, the meridional profile of the pump and the shape of the stator blades). In addition, a non-uniform flow while exiting one stage affects the rotor performance of the next stage. Therefore, improving the diffuser design improves the current stage performance as well as the performance of the next rotor. In this study, improved designs show that optimizing the stator design can increase the static pressure of the pump by 4% for single-phase flow, and 23% for two-phase flow in the simulated cases.

Wafer butterfly check valve,(also known as wafer check valve, or butterfly check valve), is one kind of check valve, which is composed of valve body, valve disc, valve stem, spring and other parts.
The wafer check valve adopts wafer connection type and has a compact structure. Due to the short closing stroke of the disc, and the forcing of the spring, the closing speed is fast, which can significantly reduce the water hammering phenomenon. This kind of wafer butterfly check valve has the characteristics of small size, light weight, sensitive action, reliable sealing and convenient installation. The butterfly type check valve can be installed horizontally or vertically, and can be applied to various mediums, such as water, steam, oils, nitric acid, acetic acid, and strong oxidizing medias.
1. How many types of wafer butterfly check valve has?
The plate of the wafer butterfly check valve is in the shape of a disc, and rotates around the shaft of the valve seat channel. Because the channel in the valve is streamlined, the flow resistance is smaller than that of the lift check valve. It is suitable for pipelines with low flow rates and infrequent changes in flow. However, it is not suitable for pulsating flow, and its sealing performance is not as good as that of the lift type check valve. Wafer butterfly type check valve can be divided into three types: single door wafer check valve(or single disc wafer check valve), double door wafer check valve(or double disc wafer check valve), multi disc wafer check valve( or multi door wafer check valve). This three types of wafer butterfly check valve are mainly divided according to the valve diameter, their purpose is to reduce the hydraulic shock when the medium stops flowing or flows back.
2. The advantages of wafer butterfly check valve:
Wafer dual plate butterfly check valve has the advantages of short face to face length, small volume, light weight, fast disc closing, low water hammering pressure, easy installation, small fluid resistance, sensitive action, good sealing performance, short disc closing stroke, small closing impact, simple and compact overall structure, long service life, high reliability, etc.

Pump Pressure Control in Hydraulic Systems - Modeling and Simulation of Dynamic Behavior 2000-01-2631
The main objective of this paper is to present the development of simulation models for use in the design of hydraulic pumps with pressure control. This includes both new compensator valve development as well as modification of existing pump design features. The discussion areas include a simulation model for two kinds of pressure regulating pumps, constant pressure and load sensing designs. The primary benefits of these models include a preview of performance in the early design phases of pump controls development, and the ability to reliably predict dynamic behavior and stability characteristics for pumps. The simulation models have been developed especially for investigation of how different geometric features of the components affect the dynamics of the system. This software tool will also facilitate the process of parameter sensitivity design studies.

RAWALPINDI: Work on Daducha Dam worth Rs6.429 billion will start in two or three weeks as Punjab government has released Rs150 million to the Frontier Works Organisation (FWO).
A senior official of the district administration told Dawn that land acquisition was underway. Payment has been started to private owners and the process will be completed soon.
However, some owners have approached Lahore High Court’s Rawalpindi bench, seeking an increase in the compensation amount.
The official said the contractor will start work on the diversion (flow pipe) and spillway in the first phase.
The dam will be constructed on upstream of Soan River. Rainwater from Murree and Kahuta hills will be stored in a lake at Daducha village near Sihala on Kahuta Road.
As many as 10 villages, seven in Rawalpindi and three in Kahuta, will come under the dam. The project will affect 218 houses, seven industrial and commercial units and other areas.
The total storage capacity of the dam would be 60,000 acre feet, dead level storage capacity 15,000 acre feet and the live storage capacity 45,000 acre feet.
The water inflow to the dam would be 77,000 cusecs and the outflow is estimated at 42,000 cusecs.
The total cost of the construction of the dam is estimated at Rs6 billion and the project will be completed in three years.
Wasa will construct a treatment plant along its main line to provide drinking water to the Rawalpindi city from the dam.
When contacted, Commissioner retired Capt Mohammad Mehmood said the Punjab government has directed to start work on the project as soon as possible to overcome the water shortage in the city and cantonment areas.

The working principle of centrifugal pump and structure
a centrifugal pump, 离心泵) On centrifugal force generated by the impeller rotates to transport liquid pump. Foreign names: Chinese name: Centrifugal water pump Centrifugal pump Chinese pinyin: li xin beng related industries: machinery manufacturing material: cast iron. Stainless steel plastic FRP. Alloy centrifugal pump: the working principle of the centrifugal pump is the use of a centrifugal impeller rotation and make the water has come to work. before the start, it is necessary to make the pump casing and suction tube filled with water, and then start the motor, make and water pump shaft to drive the impeller for high speed rotation, water centrifugal motion, be left to the impeller outer edge and the volute pump shell of the water flow into the pump pressure. Centrifugal pump model parameters and structure: the basic construction of centrifugal pump is composed of six parts, respectively, impeller, pump body, pump shaft, bearing, seal ring, stuffing box.
1, is the core part of a centrifugal pump impeller, strength higher than that of its speed, on the impeller blades and play a major role, the impeller through static balancing experiments before assembly. Impeller on the inside and outside for smooth surface to reduce friction loss of water. 2, the pump body also calls the pump shell, it is the body of the pump. Support fixed effect, and connected to install bearing bracket. 3, the role of pump shaft is connected by coupling and motor, the torque of the motor to the impeller, so it is a major part of the mechanical energy transfer. 4, sliding bearing is using a transparent oil as lubricant, fuel oil level to the line. Too much oil to the pump shaft seepage, too little bearing overheating and burn out cause an accident! Bearing in the process of pump working in 85 degrees, the highest temperature is generally run around 60 degrees Fahrenheit. 5, sealing ring, also known as minus leakage ring. 6, stuffing box is mainly composed of filler, seal ring, filler tube, packing gland, water tubes. The role of the stuffing box is mainly in order to close the gap between pump casing and pump shaft, don't let the pump in the flow outside to not let outside air into the pump. Always keeping the vacuum inside the pump! When the pump shaft and be about to rely on water seal packing friction heat to hold water to the water seal circle packing cooling! Keep the pump running. So in the process of pump run Tours of inspection to check the stuffing box is paying special attention to! Running about 600 hours will be carried out on the packing replacement. Product analysis basic structure about the basic structure of the centrifugal pump is composed of eight parts, respectively is: impeller, pump body, pump cover, hydrosphere, pump shaft, bearing, seal ring, stuffing box, the axial force balance device. 1, is the core part of a centrifugal pump impeller, its output power high speed. 2, the pump body also calls the pump shell, it is the body of the pump. Support fixed effect, and connected to install bearing bracket. 3, the role of pump shaft is connected by coupling and motor, the torque of the motor to the impeller, so it is a major part of the mechanical energy transfer 4, sealing ring, also known as minus leakage ring. 5, stuffing box is mainly composed of packing, don't let the flow within the pump outside also not let outside air into the pump. Always keeping the vacuum inside the pump! When the pump shaft and be about to rely on water seal packing friction heat pipe water injection to the water seal circle packing cooling! 6, the axial force balance device, in the process of centrifugal pump operation, because the liquid is in low pressure into the impeller, and under the high pressure flow, the impeller pressure on both sides, the pointing in the direction the entrance of the axial thrust, will cause the rotor axial channeling, wear and vibration of the axial thrust bearing, and therefore should be set in order to balance the axial force.
