Abstract

A regional frequency analysis procedure is applied to identify a climatologically and hydrologically homogeneous catchment. A complete data sets of precipitation and discharge representing 30 meteorological stations and 8 of hydrornetric stations were used for various statistical analyses. Variability of the coeficient of variation (Cv) and the coeficient of skewness (Cs) and the mean annual recipitation (MAP) and geographical locations has been explained to identify three ciimatological homogeneous regions (CHR). Also the analysis of Cv and Cs of anual maximum of daily mean discharge were examined to identify hydrologically homogeneous catchments (HHC) and application of procedure Gumbel test of homogeneity. Based on results of both identifications a climatologically and hydrologically homogeneous catchment has been specified.

Finally some remarks are presented concerning the usual statistics analysis method and some conclusions are drown for these particular example work.
