The purpose of the work was to analyse the possibility of using the conceptual EBA4SUB rainfall-runoff model to determine the design peak flows, with a specified probability of exceeding, in the catchments of the upper Vistula river basin. The basis for the study were observed series of maximum annual flows and daily rainfall for the years 1981–2014. An innovative aspect of the study was the use of a two-stage modelling process. We determined the flow hydrographs with the EBA4SUB model for various rainfall events in the first stage and then we calculated the flow quantiles based on the modeled peak flows using selected density function of probability distributions. Based on the calculations, it was found that the EBA4SUB model represents an alternative to more consolidated methods for calculating flood flows in ungauged catchments. Indeed the model gives relatively similar values to the observed flows, with percentage differences usually limited, and in average for all the investigated case studies in the range 15–25%.
