Abstract: The characteristics of cut‐throat flow measuring flumes are examined with special attention to scale effects and the transition submergence at which the flow regime changes from undrowned to drowned. Three flumes were ...

Abstract: A hydraulic model study of an existing sloping crest Crump weir is described. Two models of scales 1:10 and 1:3 were tested. At relatively large heads, the structure behaves as one half of a flat‐V Crump weir with the same ...

Abstract: The trapezoidal free overfall is analyzed by the one‐dimensional momentum equation, including an assumed pressure distribution at the brink. The pressure distribution is based on previous measurements in rectangular and ...
