摘要：
In snowy cold regions, snowmelt water serves as an important water resource. Therefore, it is necessary to estimate snow water equivalent in a dam basin and dam inflow during snowmelt season as exactly as possible. Given that snow distributions differ between inside of forest versus outside of forests, we developed a snowmelt runoff model that is able to correct the snow distribution by using observation data from snow survey. This paper reports the results obtained when the model was applied to three dams in Hokkaido, northernmost island of Japan. The accuracy of dam inflow calculation during snowmelt season was higher when proposed method is employed than when no correction is made.
