O článku:
The paper deals with the issue of T-year maximum discharge for basins with a relatively short gauging or ungauged basins by the method of regional frequency – index-flood analysis. Identification of physical regional types is carried out by the method of hierarchic and non-hierarchic cluster analysis and application of logical principles. Setting of an optimum number of physical regional types for the purpose of regional frequency analysis leans on the test of heterogeneity inter se regarding the regional coefficient values of L-variation by means of pair comparison. Division of Slovakia’s territory into four physical regional types identified by application of logical principles seems to be the optimal solution. Regional distribution functions were established by the method of L-moment ratio diagram. Values of maximum annual Q100 discharges estimated by the index flood method for the set of 34 basins within the selected regional type are 2-3 times lower than estimates obtained by application of the empirical regional formula
