COURSE AIM
To give the foundations of open channel flow and design of dams and hydro power plants.

CONTENTS
Open channel flow: Uniform and gradually varied flow: the Manning equation, hydraulic jump, sub- and supercritical flow, etc. Hydraulic structures: Sharp-crested weirs, Contracted weirs, Vee weirs, control gates, Spillways (WES). Surge waves: positive and negative waves, propagation speed.
