Flood control facilities are located in the upper reache to improve the safety level of flood control for the lower reache of rivers. Therefore. it is important to grasp the mechanism of flood propagation in valley for effective use of flood control facilities. But even mechanism of flood propagation in valley which has simple cross-section have not yet been well known. Furthermore, there are a lot of electric power dams in valley to make the best use of the difference of water elevation and volume of water. In spite of that, the effect of electric power dam operation on flood propagation has not been also studied. In this paper. we investigate the effect of valley characteristics on flood propagation based on observed data of the Go river valley.
