琵琶湖北部域及び全流域の積雪・融雪・流出モデル解析

Abstract

The aim of this study is to apply the snow accumulation, melting and runoff modelsproposed in the previous papers to the Ohura and the Takatoki Rivers located at the northernpart of Lake Biwa watershed, in the year 1985 and to improve their models. Those models aremainly improved in the melting process by the radiation and the temperature factors and theset up of liquid water holding capacity. Their results applied to both river basins wave goodagreement between the calculated and observed time series of the snowpack depth and the riverdischarge. And then the simplified form into the daily lump of those models is applied to thewhole area of Lake Biwa watershed. The result shows good reproduction in the water level ofLake Biwa.
