Abstract: 

Introduction Snow, as one of the basic factors of water supply, plays an important role in water resources management, especially in areas with cold winters and warm summers. The data obtained from snow gauges as well as temperature and precipitation time series data are generally being used to develop experimental models in order to estimate the spatial and temporal distribution of snow in watersheds. However, when reliable snow or other necessary climatic data records do not exist, using proper substitutes becomes essential. Hence, the snow cover area (SCA) derived from satellite images can be used as a representative of the amount of snow in a basin.
Moreover, Remote Sensing (RS) is a useful tool in identifying snow and calculating SCA in mountainous regions with low accessibility and deficiency of snow gauges. Accordingly, the SCA time series data can then be used as input dataset in flow forecasting by hydrologic models.
