摘要
应用甘南县实测降水数据,采用伽玛分布函数模拟了该县长系列降水数据,利用模拟出的数据推求了该县多个月份指定频率的设计降水量。研究成果表明,应用随机模拟的方法确定设计降水是可行的,与配线法相比,本文方法更加直观,且推求出的设计降水与配线法所得的结果基本一致,为推求设计降水提供了一种新方法。
Using rainfall data of Ganan County, daily rainfall process was simulated with Gamma Distribution Function, and the designed rainfall with specified frequency in several months was calculated, using data simulated for this county. Research results show that this method can be used to d termine designed rainfall, it is more intuitive compared with the Fitting Curve Method and gets the same results, and it provides a new method to determine designed rainfall.
