Research Abstract

Considering recent increase in heavy rainfall and sediment disasters in Japan, we investigated sediment production, transportation, and deposition in mountainous areas due to heavy rainfall and their social impacts from the viewpoints of geomorphology, climatology and human geography. For various study areas in East Asia and New Zealand, We assessed 1) landslide susceptibility, 2) effects of geology on landslides, 3) factors affecting alluvial-fan formation, 4) characteristics of rainfall, and 5) efforts of local people for disaster mitigation.
