Research Abstract
An implicit flood envelope curve (FEC) equation was derived as a solution to a system of a 6-parameter depth-area-duration (DAD) equation, a time of concentration formula and the rational formula. The FEC equation was respectively applied to present and future probabilistic specific discharge in six river basins in Japan. The comparison of present and future FECs shows different characteristics of change in probabilistic flood discharge especially by basin area. In addition, flood envelope curves were derived from DAD relations in record maximum areal rainfall data for each of 15 regions in Japan, and the estimated peak specific discharge from the DAD relation exceeded the estimated by conventional flood envelope curves as Creager’s and Kadoya’s in some of the regions including the South Hokkaido area.
