英文摘要：

The common problems and the programming disposal of the key processes of the sequence for the rainstorm data based- flood calculation in various regions are summarized herein, especially, the methods for the chart fitting, formula derivation, construction of the parameter grid database for rainstorm statistic, etc. are pertinently put forward herein, for which the mathe- matical fitting and derivation and the digital elevation model are introduced, so as to provide references for the programming of the procedure for the rainstorm data based-flood calculation in varius regins. This technolgy is applied to develope the procedure for the calculation of storm-flood in Jiangxi Province, and then the on-line calculation on the web page of the rainstorm data based-flood calculation is realized with reliable accuracy and convenient calculation in advance in China.
