Abstract
The purpose of this study was to obtain and prove the methods of catchment regionalization in case of annual maximum floods. Identification of Polish rivers was hold on the basis of regional frequency analyses including recognition of homogenous regions in their physical properties and river flow parameters. Results indicate the division on two regional groups: mountain and lowland catchments. Statistical tests prove the obtained regionalization and allow calculating the regional probability curves for these two catchment groups. Obtained results may be helpful in the analysis of floods in ungauged catchments and these where hydrological observations were held in a short period especially when dependency of the maximum probable flows in analysed catchments from their physico-geographical features was proved
