Abstract

Detailed topographic and hydraulic measurements were obtained in a bend of the Colorado River in Rocky Mountain National Park, Colorado, to characterize flow through the reach with a two-dimensional model. The distribution of excess shear stress is examined and how this distribution is affected by flow stage and channel curvature is explored. The results suggest that small regions of the channel contribute disproportionately to the overall sediment flux at high flows, that the size of these regions increases with stage, and that this effect amplifies with channel curvature
