二変数ガンマ分布とその適用に関する研究(4) ―短時間降雨の模擬発生―

Abstract

In this paper, a statistical technique is developed to generate short-time intense rainfall data forlong-term at a point, in which the record period is only few years, on the basis of the long-termdata observed at an adjacent observatory. The technique is based on the theory of two-variateexponential distribution. In this generation, the numerical table of conditional probabilityprepared for the standardized two-variate exponential distribution is utilized. Moreover, as anapplied example of the data generated, the design flood discharge is estimated for an assigned returnperiod.
