Abstract: The paper presents the results of an application of 3 models, adapted for the Służewiecki Stream catchment, to forecast flows with probability of exceedance 1, 2 and 10% caused by heavy rains. Flows were forecasted in 4 cross-sections of the Służewiecki Stream, located on the section from km 0+000 to 6+576. Potential flows (surface runoff) calculated using the conceptual OTTHYMO model were taken as an input data to the hydraulic HEC-RAS model, which enabled transformation of the flows in the watercourse and determining flows in the individual cross-sections (reduced flows). Independent calculations of potential and reduced flows was performed using the SWMM model, which is a dynamic model with distributed parameters. Calculated using HEC-RAS and SWMM models reduced flows with probability of exceedance of 1, 2 and 10% are similar in the computational cross-sections II, III and IV – in 7 out of 9 cases the differences in the flows do not exceed 25%. The highest values of reduced flows with a certain probability of exceedance were calculated in the cross-section II, using both models. The results of calculations indicate the possibility of use in an urban catchments of both the HEC-RAS model and the SWMM model.
