Abstract: The flow features over the broad‐crested weir with vertical upstream wall and sharp‐crested corner are analyzed experimentally. Only the long‐crested weir is considered, for which the discharge coefficient remains practically ...

Abstract: The possibility of shock‐wave reduction by a wedge‐shaped bottom drop is considered. The results are shown to depend on the so‐called shock number S. Optimum wall deflection is defined as the configuration with horizontal ...
