Part of: Sediment Transport Modeling


The behavior of the energy flow gradient as function of depth and velocity is analyzed for three flow resistance methods. In the paper, the necessary modifications introduced to the methods in order to get physically justified continuous solutions for the friction slope to be used in mathematical models are discussed. The methods discussed are those of F. Engelund, H.A. Einstern, and C. Cruickshank-V.A. Maya.
