Recently, a heavy rainfall in a short period of time occurs often and causes severe damage from a flood in various regions. The heavy rainfall due to the Baiu front gave severe damage to the southern region of Kyushu Island from July 19 to 23 in 2006. In this paper, an outline of flood disasters for the Sendai river basin in Kagoshima Prefecture from this heavy rainfall was reported. Furthermore, an improvement of the flood control operation of Tsuruda Dam in Kagoshima Prefecture was considered. By introducing the improved operation technique, it is expected that the flood control of Tsuruda Dam works well not only under usual flood conditions but also under unexpected heavy flood conditions.
