Discharge Characteristics of Rectangular Profiled Weirs

by Mathini Streetharan, Dewberry & Davis, United States,

Document Type: Proceeding Paper

Part of: Hydraulic Engineering


This paper contains the results of a detailed experimental program carried out to define the discharge characteristics of rectangular profiled weirs. The flow region where the discharge coefficient is constant is derived and a 2nd degree polynomial of h/P and h/L is proposed for deriving the discharge coefficient in other flow regions. In addition the profiles under various flow conditions are also studied.
