Abstract

According to Miwa’s paper (2012) of the traditional ways of irrigation system, weirs used to be constructed as their intake points being along the hill sides so that water supply for the paddy fields could be secured. It was conceivable that such relationships between the weirs and the riparian landforms were formed through pioneers’ routines concerning with rivers. This paper made it clear that these relationships still existed in 116 cases among 891 cases of weirs in Asahi river system. Therefore, it was possible for visitors of these weirs to see how the pioneers had concerned with the rivers before modern times even though there might be only modern facilities right in front of them. These weirs were even distributed over the main stream, the main first tributaries and tributaries they accompanied. The distribution was limited to the areas of riparian landforms of either side erosion or downward erosion of the mountain region. They rarely existed in the areas of alluvial plains and buried valleys. The factors that many other weirs were not in such relations with the adjacent landforms remained unclear. It was necessary to look for the origins and the transitions of those weirs.
