Performance of lateral velocity distribution models for compound channel sections

摘要

In this paper, the scope of 2D-Horizontal and 1D-Lateral models for lateral velocity distribution is addressed, and their relative and absolute performances are tested by making comparisons between their predictions, on the one side, and experimental and field velocity data, on the other side. The models considered are: the Divided Channel Method (DCM), the Lateral Distribution Method (LDM) and a 2D Horizontal hydrodynamic finite-element model (RMA2).
