Abstract
The concept of risk based only on the estimate of probability is referred to as a single scale conception. The paper deals with estimates of maximum discharge with different exceedance probability for small basins with relatively short gauging or for ungauged basins by the method of regional frequency analysis - index flood. Such a quantification of flood risk analysis is an indispensable prerequisite for flood risk mapping. Estimation of flood risk by application of regional frequency analysis involves solutions to three key problems: 1) division of the study territory into regional classes, 2) selection of regional distribution functions and estimate of their parameters, and 3) regression estimate of mean annual maximum discharges.
