Hydrological Modeling of Murray River Basin Using The Hydrological Simulation Program-FORTRAN Model

Abstract

Snow Water Equivalent can be a field for modeling runoff in mountainous catchments. In this regard, the use of satellite data and distributed hydrological models has grown dramatically to simulate runoff from snow water. Accordingly, the HSPF (Hydrological Simulation Program - FORTRAN) model has been used for a mountainous catchment area in Australia to show that it can overcome the lack of conventional snow data such as depth and density of snow using a combination of index-snow temperature and precipitation-runoff models. This model is based on a physical and semi-distributed model for simulating hydrological processes in the catchment area. Therefore, the satellite data and images in UTM image system for inference of land cover and land use, DEM (Digital Elevation Model) and SCA (Snow Cover Area) are used. The model was able to simulate the amount of runoff in the catchment as well as the annual changes in water equivalent to snow reasonably. Hence, The parameter of snow water can be applied on multi resolution analysis using wavelets (WNF) approach to increase the forecast accuracy. The results showed that reliable estimation of the snow water equivalent and simulation of runoff from snow water can be done using distributed hydrological models and satellite data of snow cover area.
