Abstract
en
For comprehensive water management and water environmental planning in large river catchment areas, the longterm hydrologic cycle need to be understood. In cold, snowy regions, the snow process (falling, accumulation, and melting) plays an important role on the hydrologic cycle. An understanding of snow cover volume and snowmelt volume is essential. Analysis of the water balance of the catchment area also requires accurate estimation of evapotranspiration, which is affected by soil and vegetation. This report applies a two-layer model toward estimating the evapotranspiration, snow cover volume, and snowmelt volume of 1-km meshes. The model incorporates heat balance between the air, the vegetation layer, and the ground surface. Observed values for evapotranspiration, snow cover volume, and snowmelt volume were compared with estimates generated by the model. These estimates were used to reproduce long-term runoff, in order to examine the validity of the estimates. The estimates were found to accurately reproduce the measurements. This has enabled the quantification of long-term hydrologic factors for cold, snowy regions.
