英文摘要	The aim of this study was to assess the runoff amount from a catchment characterized by diverse land uses by using the Soil Conservation Service Curve Number (SCS-CN) method based on Curve Number (CN) defined for dominant homogeneous elementary sub-regions. The calculations employed the SCS-CN method, involving the division of the catchment in two homogeneous parts and determining the runoff amount. The obtained results were compared with the results provided by three other CN determination methods, i.e. the Hawkins function, the kinetics equation, and a complementary error function peak. The catchment is located in a mountain dominated by forest land cover. Empirical CN-Precipitation (CNemp-P) data pairs were analyzed using the mentioned methods, and the highest quality score was achieved from model 1. The results suggest that dividing a catchment into two homogeneous areas and determining their separate CN parameters, used later on to calculate the runoff by means of the presented approach, could be an alternative to the standard methods. The described method is relatively easy, and as it does not require an adoption of numerous parameters, and it can be employed for designing hydraulic facilities.
