Abstract

Generally in flood studies, two types of information will be offered which are namely as peak instantaneous discharge and flood hydrograph with different return periods. The main purpose of the present research is determination of regional coefficient Diken’s equation for calculation of peak flood with any return period. In this study, because of lacking measurement data in Sheyvand basin, the peak instantaneous discharge data of existing hydrometric stations in outline basins has been used. The outline rivers peak flow data was collected, controlled, validated and accomplished.The long set of peak flow data was analyzed by different statistical distributions. According to the results of statistical tests, the best distributions for each hydrometric station was selected and the floot peak values with different return periods was estimated by the selected distributions. By creating correlation terms between area parameters and flood data with any return period, one area discharge equation was achieved according to Diken’s equation. By correlating between C & N parameters that are equation coefficients and return period, two equations for calculating both of the considered parameters were obtained. Replacing these equations instead of C & N in Diken’s equation, final equation in order to estimating flood amount in study region was achieved. Finally, flood values were estimated flood amounts with different return period for Sheyvand basin by this method.
