Snowdepth model during snowmelt season in the Taki dam basin

Abstract

An evaluation method of total precipitation (snow and rain) volume in the Taki dam basin from a few meteorological points is discussed. This method is based on comparison of snow depth data at observation points with the snow survey conducted once a year. 1) Evapotranspiration and groundwater balance are evaluated by Thornthwaite method and by simple model respectively. 2) Water balance in the basin is studied in snowmelt season. 3) Taking account of the relationship between snow moisture volume and snow area from NOAA-AVHRR data, snow depth distributions is estimated.
