Abstract: The paper presents an analysis of suitability of the conceptual rainfall-runoff model by Nash for simulation maximum flows in the Służewiecki Stream catchment to the profile “Rosoła”, located in Warsaw. The range of the analyzes included determining the parameters of the Nash model (N, K) for 13 rainfall-runoff events and an assessment of the compatibility between measured and simulated flows. The analysis was conducted for two different sizes of the catchment area (14.7 and 31.2 km2), two time steps of calculations (10 and 30 minutes) and two locations of the end point of the direct runoff hydrograph, in order to determine their impact on the flow simulation error and the parameters of the Nash model. The calculations were performed using a owned computer program. Admission to the calculations of two different sizes of the catchment area has little impact on the compatibility between measured and simulated maximum flows. The compatibility between these flows is much greater in the simulations with the time step of calculations of 10 minutes than with the time step of 30 minutes. The analysis showed that the choice of the end point of the direct runoff hydrograph has a big impact on the flow simulation error and the values of parameters of the Nash model.
