Time Scale for Scour Downstream of Hydraulic Jump
Scour downstream a hydraulic structure takes time to develop. Therefore, for a river in which peak flows are of short duration, the time history of scour development is of major importance. The paper briefly describes the work of Breusers on the time scale of local scour downstream of estuary closure structures and then extends it by reference to a program of experiments to the case of local scour downstream a hydraulic jump. The paper includes an example calculation of the determination of the time scale between a model and prototype overflow weir with plunge-type dissipator, subject to scour downstream.
