暴雨重现期的估算，是依据历史洪水顺位或重现期，做该流域内均匀雨量点不考虑重现期的点雨量理论频率计算，求出各雨量点的均值及ＣＶ值和流域平均值，以流域暴雨均值除暴雨量，即得各雨量点暴雨的Ｋ值，利用数值逼近法，反求该Ｋ值的重现期，将各点的重现期加权平均直至逼近与同次洪水重现期为止，暴雨中心点雨量的重现期即为所求的暴雨重现期。文中并以实例加以说明。
The estimation of heavy rainfall recurrence period is based on the history flood recurrence or recurrence period, and calculates the theoretical point frequency of point rainfall without considering the recurrence period of the average rainfall point in the basin, and calculates the mean and CV values of each rainfall point and the mean Value, in order to deduct rainstorm from the rainfall mean value of the basin, that is, the K value of rainstorm rainstorm, the numerical approximation method is used to reverse the reappearance period of this K value, and the weighted average of the recurrence times of each point is approached until the same flood Reproductive period, the heavy rainfall at the center of the recurrence of the storm that is required for the heavy rain period. In the article and examples to illustrate.
