Abstract

RAINFALL FREQUENCY ANALYSIS is a major task for water resources planners and hydrologists. Because of wide and different rainfall temporal and spatial distribution over IRAN, at site frequency analysis is not sufficient for this purpose. It is very important to regionalize rainfall frequency over homogeneous rainfall spatial groups. A hierarchical CLUSTER ANALYSIS and L-MOMENTs regional frequency analysis were used in this study to find homogeneous rainfall groups and regional RAINFALL FREQUENCY ANALYSIS. The study showed that there are eight homogeneous rainfall subregions over IRAN, which can present geographic and climate variability of IRAN, but no single parent distribution was found for each subregion. Although regional homogeneity measure, H1, showed that a 3-parameter log normal distribution performs regional distribution of IRAN, but three LN2, P-III and GEV distributions perform better than other distributions for subregions derived from CLUSTER ANALYSIS.
