Descrição

In this work the distribution and mean of transverse turbulent diffusion coefficient in straight alluvial rivers are determined using a vertical turbulent diffusion coefficient and a hydraulic geometry equation relating the depth to the lateral position in the section. The cross- section averaged transverse turbulent diffusion coefficient was found to be in good agreement with 138 sets of experimental data.
