Abstract

 This paper presents a snow-fall, load and melt model based on snow depth, precipitation, and meteorological data from the Hokuriku region of Japan, which is known worldwide as a heavy snow region. The model includes sub-models for the determination of snow-fall and snow melting, and for calculation of the densities of fresh snow and the snow layer. Daily snow depth was calculated in comparison to observed depths. Air temperature and humidity data were selected as factors related to snow-fall. In the snow loading sub-model, fresh snow density and average density of the snow layer were calculated separately. Snow melt was caluculated using a simple equatuion incorporating air temperature, net radiation, and soil heat flux. Calculated results showed good agreement with observed snow depth data and obseved snow density. Assessment of the importance of model parameters and factors revealed that some had negligible effects on practical calculations.
