Abstract

Along the Usui River in central Japan, three well-developed terrace levels are observed. To clarify the response of fluvial systems to climatic change, terrace sediments were interpreted from the viewpoint of paleohydraulics. Using the grain diameter of terrace sediments, paleo-tractive forces were evaluated based on the correlations between tractive force and grain diameter of the sediment on the present river bed. The valley filling was caused by the diminution in tractive force related to the decrease in heavy rain produced by typhoons during the glacial ages. During the interglacial ages, the reverse responses occurred due to the increased incidence of typhoons
