The characteristics of flow behavior and bed variation in a diversion of a river were investigated experimentally. The experiment was conducted on the fixed bed as well as mobile bed to examine flow mechanism and bed morphology development in a diversion of a river. Through the experiments, it was found that the characteristics of flow and bed variation in a diversion were classified into several patterns by the channel shape and relationship of water surface profile on upstream and downstream of a diversion. Numerical simulations of flows in diversion of a river were also performed by quasi-3D free-surface flow model. It shows that the model can reproduce the complex behavior of the flows with reasonable accuracy.
