Description: Miscellaneous Paper
Abstract: A case is made for providing for or preforming a scour hole in which flow from a hydraulic structure can expand and dissipate its excess energy in turbulence rather than in a direct attack on the channel boundaries. Examples are given which demonstrate that riprap schemes providing for flow expansions make it feasible to stabilize the channels with rock of an economical size and provide factors of safety against riprap failure and costly maintenance.
