摘要：

Unsteady depth-varying open-channel flows are really found in rivers in flood. Owing to the highly accurate laser Doppler anemometers (LDA) a valuable database of unsteady open-channel flows is now available. Almost all researches have been conducted not by numerical simulations but by laboratory experiments with LDA. These LDA measurements of unsteady flows are, however, sometimes very difficult to be conducted. Therefore, in this study, numerical simulation of unsteady open-channel flows on a smooth bed was carried out by using the RANS model and VOF method.
