Research Abstract

Initial barrier was generally formed the alluvium in the Niigata plain about 8000 ago. It has been proven that the delta system advances in the Agano River watershed. In Numazawa volcano in the Tadami River middle class area in Fukushima Prefecture, there was the pyroclastic flow eruption about 4700 ago. The pyroclastic flow temporarily stopped Tadami River. The large-scale floodflow by a collapse of the dam over about 100km flowed Tadami River and Agano River. The enormous pyroclast which this flood brought about in the plain rapidly advanced of the Agano River watershed of the plain of the delta system. The whole barrier column advanced by this.
