Estimating Velocity and Scour in River Bendsby D. C. Baird, Bureau of Reclamation, United States,

Abstract: A one-dimensional, steady-state, stream tube model was used to simulate hydraulic characteristics at a cross section. This enabled computation of higher velocities on the outside and lower velocities on the inside of a bend that compared favorably with measurements. The model was then used to compute channel velocities in cross sections for the design discharge. From these simulations, scour was computed and a new cross section predicted.
