Effects of ramp width variation on the hydraulic conditions of spillway that affect downstream migrating fish

Abstract An experimental investigation was conducted to elucidate the effects of a 45º upstream spillway ramp with varying spanwise width ratios (10%, 25%, 50%) on the turbulent flow characteristics used to guide fish downstream. A particle image velocimetry system was employed to acquire the veloci...
