简介：把土壤的侵蚀基于降雨并且在暴风雨事件推迟了沉积运输，一个方法被建议预言山峰推迟了沉积集中并且在山峰降雨以前基于降雨特征在分水岭推迟了沉积产量紧张。统治的降雨特征因素达到顶点推迟的沉积集中Cp是降雨侵蚀因素裁判员，区域一般水准降雨ip1的第一山峰降雨紧张和先前的降水索引Iap；在暴风雨事件统治推迟的沉积收益Yss的降雨特征因素是全部的降雨P，推迟的沉积收益因素Rsf和前身降水索引Iap。这研究作为研究目标在南部的台湾沿着Lao-Nung河在Liau-Kwei观察车站集中于分水岭，并且采用PSED模型为分析在11个暴风雨事件模仿分泌物自记水位计，推迟的沉积集中自记水位计和推迟的沉积产量。分析结果证明在之间有好关联上述象被使用表情(13)并且(要预言的Yss，这样创新的Cp和Yss一样的降雨特征因素和Cp14)。这二表情被利用在2009预言台风Morakot的Cp和Yss，并且结果与从由使用PSED模型的模拟的那些相比。在那里的比较表演的结果是在预言的一个好能力。为为水资源设备的有效操作的利益预言一个暴风雨事件的Cp和Yss是必要的分水岭，上述的降雨特征因素能被利用为预言建立适用的模型。
