Evaluation of gsmap and gauge rainfall serging chnioues for stream flow modelling using swat model over the Lam river basin

The research combined satellite-based rainfall data with observed rain gauge data using bias-correction method to adjust satellite data coefficients, this approach takes advantage of spatial distribution of the satellite rainfall and the accuracy of the rain gauge observation. These rainfall products were employed as input in SWAT model and the simulated discharges were validated with the measured discharge at 3 gauges within the Lam River Basin. The results indicated that the combined products provide the better simulation comparing with using single product, ground or satellite observation, based on the different efficiency criteria which commonly used in hydrology. This research is significantly important for water resources management on river basin, especially for the river basins where ground observations are limited or not available.
