Abstract: Watercourses of some rivers in Saga Plain have been rerouted in the Warring States period or early Edo period and they have unique shapes. As there have been many lowland areas in this plain, problems of water shortage and inundation occurred frequently. Therefore, sophisticated irrigation and drainage systems exist in this area and the rerouting of the watercourses may be considered inevitable. There are many flood damage prevention facilities in the river or near the river of the Saga Plain. It is significantly useful to find out and restore these remains and clarify their functions to consider a future flood control, including catchments basin operations. In this study, a traditional flood management technology in Kase River basin, Japan, is discussed, and its usefulness for the future is explained.
