[2G10] Hazard curve analysis for heavy snowfalls risk

*Risako Nakashima1, Akari Koike1, Takaaki Sakai1 (1. Tokai Univ.)

Keywords:heavy snowfalls , external hazard, global warming

As for the evaluation of snowfall hazard based on meteorological data, the hazard curves calculated on amounts of snowfall per day and the snow heights for the existing LWR sites. Based on the results, reference values of the snowfall hazard are compared for design extension conditions for each site. In addition, possibility on an increase of a short-term heavy snowfall was discussed caused of a progress of the global warming.
