Physical-based model of fish movement in fish extraction facilities
Fish collection or diversion facilities are structures designed to remove fish from a channel where they may be endangered from pumps, power plants, or irrigation systems. The Tracy Fish Collection Facility in the Central Valley of California (USA) collects endangered and economically important species before they can enter the Delta Mendota Canal. We describe the structure, sensitivity, and pr...
متن کاملTotal mercury and methylmercury levels in fish from hydroelectric reservoirs in Tanzania.
Total mercury (THg) and methylmercury (MeHg) levels have been determined in fish species representing various tropic levels in four major hydroelectric reservoirs (Mtera, Kidatu, Hale-Pangani, Nyumba ya Mungu) located in two distinct geographical areas in Tanzania. The Mtera and Kidatu reservoirs are located along the Great Ruaha River drainage basin in the southern central part of the country ...
متن کاملFish population genetic structure shaped by hydroelectric power plants in the upper Rhine catchment
The Rhine catchment in Switzerland has been transformed by a chain of hydroelectric power stations. We addressed the impact of fragmentation on the genetic structure of fish populations by focusing on the European chub (Squalius cephalus). This fish species is not stocked and copes well with altered habitats, enabling an assessment of the effects of fragmentation per se. Using microsatellites, ...
متن کاملHydroelectric pumped storage
Hydroelectric Pumped Storage (PHS) is the most widely utilised form of large-scale electrical energy storage (EES). The energy is stored as the potential energy of water raised against gravity. Water is pumped from a lower reservoir (1) to a higher reservoir (2), using the energy provided by the pumping unit (3), storing it as potential energy in the water. Figure 1 is a simple scheme of a PHS ...
متن کاملThe Effects of Run-of-River Hydroelectric Power Schemes on Fish Community Composition in Temperate Streams and Rivers
The potential environmental impacts of large-scale storage hydroelectric power (HEP) schemes have been well-documented in the literature. In Europe, awareness of these potential impacts and limited opportunities for politically-acceptable medium- to large-scale schemes, have caused attention to focus on smaller-scale HEP schemes, particularly run-of-river (ROR) schemes, to contribute to meeting...
