THE APPLICATION OF SNOWCOVER AREA EVALUATION FROM REMOTE SENSING DATA TO SNOWMELT RUNOFF TANK ANALYSIS

Abstract

Combined snowmelt and rainfall runoff during active snowmelt season is predicted by using tank model and the model parameters are optimized by applying Powell's conjugate direction method. The parameters optimization is conducted for the data of water year 1988. The obtained set of optimized model parameters is used to predict the runoff of water year 1989. The input data for the model are snowcover area evaluated from remote sensing data, daily precipitation, daily mean air temperature and daily observed runoff.
