Abstract
Extreme precipitation is forecasted by global warming with GCM (Global circulation model). The water resource crisis and an increase in the disaster are feared with cause as extreme precipitation in the future. It is necessary to evaluate a high dangerous region by the spatial-temporal distribution to risk mitigation. The risk map is useful of counter measures planning. The situation of take a counter measure can be understood from the time change of the risk map.
We made the risk maps of the slope hazard in JAPAN by using forecast climate data (RCM20Ver.2: JMA) and digital geographic information data. I evaluated slope hazard risks about 1981-2000(Present climate), 2031-2050(Near-future climate), 2081-2100(Future climate). The risk indexes are slope failure probability.
