Özet

Regional flood frequency analysis was performed using L-moments. The analysis uses annual maximum flood data observed at a desired project location or streamgaging station to estimate flood quantiles. Regional flood frequency analysis involves four stages: screening of the data, identification of homogeneous regions, choice of a regional frequency distribution, and estimation of the regional frequency distribution. Gauging sites of study basins were found to be homogeneous after redefinition of regions.
