Observed results are indicated as follows: 1) the ground surface soil at the hillslopes was always freezing, 2) there was rarely frozen soil near the" stream channel because snowpack serves as a good thermal insulator, 3) the diurnal change of snowmelt runoff was rarely recognized except in the maximum snowmelt season and 4) the swell of long wavelength of hydrograph occurred in the early snowmelt season. To make clear the cause of above runoff characteristics, this study focuses on the overland flow over the hillslope surface and subsurface flow infiltrated in soil layers. By applying a 4X3 zoned tank model, it shows that the effects of frozen soil on the snowmelt runoff are estimated by the value of model parameters., application/pdf}, pages = {127--132}, title = {凍土層を有する少雪寒冷地の融雪流出特性に関する研究}, volume = {42}, year = {1998} }
