Snowmelt Runoff Analysis Based On The Distribution Of Snow Water Equivalent

Abstract

The objective of this paper is to apply the distributed snowmelt runoff model to a basin with no information on snow covered area (SCA). At first, we estimate the spatial distribution of snow water equivalent (SWE) using the snowmelt distribution model on the snow-line already obtained. The changes of SCA during snowmelt season are simulated successfully using the topographical distribution of SWE. The result of application of the distributed snowmelt runoff model including the simulated SCA is in good agreement with observed hydrograph.
