Flow patterns in a mountain stream

Lisa C. Hubbard, Colin Reginald Thorne

Open publisher page 2 citations

Abstract

This paper deals with the occurrence of subcritical and supercritical flow, and their related flow patterns. A flow pattern theory was presented by Bathurst et al., (1979), that considers the relation between relative submergence, Froude number and the appearance of hydraulic jumps. This theory does not seem to represent what is found in the field, as the patterns are not dependant on the Froude number and velocity. It may be that this relationship is masked by more dominant variables, but the importance of the relative submergence and depth of flow is demonstrated.
