Abstract	The paper presents an assessment of the applicability of HEC-HMS programme to simulate a precipitation flood event in an ungauged basin. The programme has been developed by the Department of the Army Corps of Engineers and enables conducting hydrological calculations for basins with different characteristics and including a number of meteorological factors. The application of this model in Polish conditions was verified in the basin of the Stobnica River – a right tributary of the Wislok River. The calculations were carried out for the flood event caused by a continuous rain, which occurred in April 1998. Four hydrological models were compared: geomorpho-climatic instantaneous unit hydrograph by Nash – GcIUH_Nash, Snyder's synthetic unit hydrograph with the determination of parameters by regression models – Snyder_reg and standard method – Snyder_stand and Clark's instantaneous unit hydrograph – IUH_Clark, where the model parameters were optimized in the programme. The calculations revealed that the best simulation results were obtained with the Snyder_stand and Snyder_reg models. Further research should be directed to verifying the applicability of HEC-HMS programme for hydrological analyses of much more extensive hydrometric material and basins with different characteristics.
