Description :
This study examines the rate of recession of Shomyo Falls, which consists of Pleistocene welded pyroclastic flows deposits in Toyama Prefecture. The discrepancy between the geology-based and equation-based recession rates indicates that some factors, not taken account of in the equation, significantly influence the recession rate. The AA. suggest that a factor in the rapid erosion of the waterfall is a large amount of transported sediment acting as abrasive material, which is supplied from high mountains in the watershed above the waterfall.
