| Description | The SCS-CN method is a globally used approach to simulations of surface runoff for its simplicity and applicability. Nevertheless, relevant simulations require the proper setting of the model’s components. This work focuses on optimization of initial abstraction ratio lambda in the Husí Potok catchment, the Czech Republic, and its sub-catchments. Due to favorable morphology, the watershed is prone to flash floods and accurate modeling of surface runoff is of high interest. The analysis was conducted using pairs of discharge and rainfall measurements. The results outline that the traditional value lambda 0.2 is too high in this watershed and should be reduced. |
