Abstract
Today, in order to plan and manage water resources in catchment basins, it is very important to know the parameters that play a role in modeling the process of converting precipitation into runoff. In this research, the effectiveness of HEC-GeoHMS model in estimating and simulating floods in the Tajen River catchment was investigated. In this regard, first, the maps and information needed for the aforementioned model were prepared and entered into the HEC-HMS model for flood simulation. The results show that there is a big difference between the observed and calculated values. On the other hand, in order to reduce the error, the CN parameter was selected as the most effective parameter. On the other hand, sensitivity analysis was done on the parameters of the model. Also, by changing the values of the CN parameter in the calibration, the difference between the calculated and observed values was reduced. The simulation results showed that the model with a relatively good approximation can be used in the rainfall-runoff simulation in the Tajen River catchment.
