土石流の現地調査について

Abstract

Among various methods of scientific study on rocky mudfiow, the field survey plays animportant role in order to clarify the complex phenomena and real damage occurrence.For the synthetic investigation, physical measurement, geomorphological and geological surveyhave been carried out concurrently by small groups, and the methods and results of each groupswere discussed by all group members.This paper describes the physical measurement on the moving state of rocky mudflow at theeastern slope of Mt. Vake, geomorphological and geological survey on erosion and depositionregions around Mt. Vake and Mt. Nagiso, and some considerations were taken into about therelation between land utilization and mudflow damage at mountainous regions (Mt. Yake andMt. Nagiso) and urban area (Shugakuin district, Kyoto City).
