Abstract

Abstract: Numerical simulation is an effective method to study the law of flood evolution. Adopting a one-dimensional two-dimensional coupling approach, the river flood evolution uses a one-dimensional model and the flood protection areas on both sides of the river adopt a tow-dimensional model. The two-dimensional model is laterally connected to the one-dimensional model, which can simulate the flood evolution process in the two-dimensional flood protection area after the flood of one-dimensional river overtopping the dam. A one-dimensional and two-dimensional coupled overtopping dam flood model in Wuyij River basin is established. The model calculation accuracy is relatively high and the results are overall reasonable.
