Abstract: Some traditional counter measures for flood disaster mitigation still work in Japan. One of the traditional measures is an open dyke system that is discussed in this paper. The open dyke system is still remaining along the Katsura River in Kameoka Basin, Kyoto, Japan. In this work, it is the objective to investigate how the open dyke works in the adjacent area to mitigate the damage of inundation. Calculated result shows that some part of village can be absolved from inundation. Difficulty of evacuation is also discussed in this paper by using the criteria of safe evacuation evaluated with flow depth and velocity.
