ABSTRACT: Simulation and modeling the stream flow provide major data while it is a
challenge in mountainous basins with regard to the important role of snowmelt
runoff as well as the data scarcity in these places. The main purpose of this
paper is to examine the capability of an integrated application of remote
sensing data and Snowmelt Runoff Model (SRM) to simulate scheme of daily stream
flow in the snow-dominated catchment, located in the North-East region of Iran.
The main parameters of the model are Snow Cover Area (SCA), temperature and
participation. Regarding to the lack of measured data, the input variable and
parameters of the model are extracted or estimated based on accessible maps,
satellite data and available meteorological and hydrological stations. The
changes of snow-cover, as spatial-temporal data, which are the most effective
variable in performance of SRM, are obtained from the Moderate Resolution
Imaging Spectroradiometer (MODIS) eight-day composite snow cover images. The
evaluation of the model application efficiency was tested by the coefficient of
determination and the volume difference, which are 0.85% and -4.6%
respectively. The result depicts the relative capability of SRM though it is
evident that the more accurate the estimation of model parameters, the more
efficient simulation results can be obtained.
