Farm ponds, reservoirs and in-stream weirs exist in most lowland UK river catchments often dominate over natural features such as lakes, wetlands, floodplains debris dams. Artificial structures have served multiple purposes, including provision of power for historic flour milling iron ore crushing water medieval fishponds, canals, crop irrigation potable supply. Although unintentional, they can...

Sediment delivery to reservoirs causes a reduction in storage capacity, leading emergency water conditions and difficulties managing resources dams, especially on dry land. This paper presents methodology for calculating the time period of sedimentation-induced operational failures supply dam, based reservoir’s daily balance equation. The method applies shot noise stochastic model generate stre...

The travelling population is increasing globally year on year. International tourist arrival figures reached 1087 million in 2013 and 1133 million in 2014; of which 53% and 54% respectively accounted for air transport. The water on board aircraft is sourced from surface or ground water; piped to a central filling point and distributed to each aircraft by water service vehicles at the home base ...

Abstract Displacement monitoring method of reservoir dam is a key research topic at present. In order to better display the overall efficiency horizontal displacement and vertical monitoring, numerical simulation analysis ecological small based on maximum entropy algorithm proposed. The virtual value calculated by algorithm, probability distribution function random variables obtained. comprehen...

Sediment flushing of reservoirs is an operational technique, whereby previously accumulated sediments in the reservoirs are hydraulically removed by accelerated flow when the bottom desiltingoutlets of the dam are opened. In this research, the process of sediment flushing is simulated by a three dimensional numerical model in which sediment and flow interaction are reflected in the reservoirs. ...

Optimal operation of water resources in multiple and multipurpose reservoirs is very complicated. This is because of the number of dams, each dam's location (Series and parallel), conflict in objectives and the stochastic nature of the inflow of water in the system. In this paper, performance optimization of the system of Karun and Dez reservoir dams have been studied and investigated with the ...

The growing scarcity of potable water supplies is among the most important issues facing many cities, in particular those using single sources of water that are climate dependent. Consequently, urban centers are looking to alternative sources of water supply that can supplement variable rainfall and meet the demands of population growth. A diversified portfolio of water sources is required to e...

This paper describes research undertaken to develop an approach for facilitating an initial hazard assessment and risk characterisation for a proposed indirect potable reuse scheme, as part of the water safety plan recommended by the World Health Organization. The process involved a description and evaluation of the catchment, which was the sewerage system supplying the sewage treatment works t...
