Title

THE FREE OVERFALL IN CIRCULAR SECTIONS WITH DIFFERENT FLAT BASE IN SUPERCRITICAL AND SUBCRITICAL FLOW REGIMES

Pages

  1105-1116

Abstract

 Introduction: A free overfall offers a simple device for flow discharge measuring by a single measurement of depth at the end of the channel yb which is known as the end depth or brink depth. When the bottom of a channel drops suddenly, the flow separates from sharp edge of the brink and the pressure distribution is not hydrostatic because of the curvature of the flow. In channels with subcritical flow regime, control section occurs at the upstream with a critical depth (yc). Although pressure distribution at the critical depth is hydrostatic, the location of the critical depth can vary with respect to the discharge value. So, the end depth at brink is offered to estimate the discharge. …
