The Forms of Flow on the Angular Broad-Crested Weir

Abstract

This report explains by experiment and theoretical analysis that the qualitatively different forms of flow appear on the angular broad-crested weir by quantitative variation of depth of overflow and of length of weir-crest.
It makes clear the next:
1) The hydraulic meaning of Mostkow's indices classifying the flow, and correction of those.
2) The range of flow in which the minimum depth equal to one half depth of overflow, founded by Doeringsfeld and Barker, occurs.
