Abstract

The overflow discharges, under the overflow as well as submerged overflow conditions, from a river with or without retarding plantations into a flood plain are investigated experimentally and numerically. The analysis is directed toward the examination of the overflow discharges by the overflow discharge formula as well as the numerical analysis, simultaneously solving flows in a channel and inundation flows in a flood plain. The dynamic inundation analysis model used in the analysis comprises the finite volume method on unstructured grid using fluxdifference splitting (FDS) technique. We found that the model is much superior to the formula in predicting the overflow discharges with or without retarding plantations.
