Abstract: Two of the authors have reported previously on the hazard that a conventional hydraulic jump with a uniform reverse surface roller presents to white water boaters. The intent is to create a hydraulic jump that is safe for boaters. This is accomplished by maintaining a horizontal supercritical discharge at the surface, thus eliminating dangerous reverse (or upstream) surface currents. Because numerous flow conditions are typically considered, the analysis technique has been computerized. Two projects of McLaughlin Water Engineers, Ltd. , have involved modeling efforts that were very useful, both in academic terms to confirm theory, and to refine the design to achieve good initial prototype performance. Results of a modeling effort for the design of a white water bypass at a grade control structure on the Arkansas River in Pueblo, Colorado are presented herein.
