In order to design and construct many of the hydraulic structures such as dams, there is a need to determine the amount of river discharge. In rivers without gauging stations, it is necessary to calculate their inflows by using the hydrological models. SWAT is one of the numerical models that are widely used for this
purpose.
For calculating the basin discharge, the model requires effective metrological data such as precipitation,temperature, wind speed, solar radiation and relative humidity on the one hand, and the data related to the basin surface such as curve number and roughness coefficient on the other hand.
In this research, Kasillian River discharge has been calculated as a case study and has been verified using data from Valikben hydrometric station, which is placed at the basin outlet. Furthermore, the impact of each input data on the calculation of water flow has also been studied.
