Description
Summary:Alteration of hydrological regime due to diversion-type hydropower station has significant impacts on the fish habitat in the de-watered river channel.This paper evaluate the alteration of hydrological regime by using the Indicators of Hydrologic Alteration (IHA) and the Range of Variability Analysis (RVA),analysis the impact on the fish habitat.The IHA&RVA analysis suggests that the construction of diversion-type hydropower hydrological seriously effectshydrological alterations of downstream and damages the fish habitat. Instream flow and hydrogragh study should be developed urgently.
