Supercritical flow over a rectangular side weir

Masoud Ghodsian

Open publisher page 66 citations

Abstract

Side weirs are flow-diversion devices widely used in irrigation, land drainage, and urban sewage systems. Hydraulic characteristics of a sharp-crested rectangular side weir under supercritical flow have been studied in this paper. The concept of elementary discharge coefficient for supercritical flow is introduced. The elementary discharge coefficient has been related to head weir height ratio and local Froude number. Suitable equations for the elementary discharge coefficient are introduced.Key words: supercritical flow, sharp crested, rectangular side weir, elementary discharge coefficient.
