Abstract

Increasing demand of energy and limited conventional energy sources (coal, petroleum, natural gas, etc.) initiated the alternative thinking of hydropower projects. Due to easy and high head availability in mountainous regions, India has immense potential of hydropower. Spillways are the one of the important elements of hydropower projects. Spillways are generally used in the hydropower to spill the excess amount of water. Piano Key Weir is the ungated spillway structure generally used to get high discharge intensity under limited width. This study formulates the empirical relationship between the head and discharge over Piano Key Weir. This study also evaluates the weir coefficient values of Piano Key Weir through HEC-RAS modeling.
