SQRT-Exponential Type Distribution of Maximum
The authors present the square-root exponential type distribution of the maximum, or SQRT-ET-max distribution, as the distribution to be applied to the annual maximum series of the total amount (or depth) of a single rainstorm. The presented distribution is theortically derived, and is as simple in expression as conventional ones. It as two parameters and, thus esimates them more stably than distributions with three or more parameters. Futhermore, it is an good as or superior to conventional 3-parameter distributions in overall fitness to frequency distribution of annual maximum depths of a single rainstorms and rainfalls of about 24 hours.
