Archimedean screw as fish-friendly turbines for harnessing hydropower potential

Hydraulic energy is one of the most important sources renewable today. It also a complementary source to other sources, being only that offers an nonpolluting storage capacity (through pump facilities). Another essential quality hydraulic its ability regulate system allow integration in which process generating depends on factors cannot be controlled (sun, wind, etc.). However, hydropower plants can damage ecosystems, especially by affecting fish within their turbines. Usually, pass unharmed through The main exceptions generally include some low head (below 8 m) turbines, such as Very Low Head (VLH) turbine and screw turbine, but lately strategies have been developed for high as: passage facilities friendly turbines Alden Minimal Gap Runner (MGR). this article deals with screw-type low-head fish-friendly how implement them order obtain sustainable green energy.
