Abstract

Introduction In dam reservoirs whirlpools cause problems such as increased energy loss, decreased discharge coefficient, increased noise, and vibration at intakes (Knauss, 1987).Hecker (1981) divided vortices based on visual classification from weaker to stronger into 6 types. For a powerhouse tunnel intake it is assumed that in VORTEX type 5 debris and some air bubbles are entrained to the tunnel and in the strongest VORTEX (type 6) a stable air core from water surface is formed in the center of the VORTEX and air is entrained into the power tunnel steadily. By reducing the submergence depth in power intakes, the strength of vortices increase regarding to the unchanging discharge. However in ORIFICE SPILLWAYs, the discharge is a function of submergence depth and by decreasing it, the discharge will decrease.
