Flow-Measurement Flumes of Rectangular Compound Cross Section

Abstract

A series of laboratory experiments were carried out in a flow-measurement flume of a rectangular compound cross section to investigate the effect of the throat width and step height on the values of discharge coefficient, approach-velocity coefficient, and modular limit. For this reason, nine different models made of Plexiglas were tested in a horizontal laboratory flume for a large range of discharges. In each test, the head,
