降雨雨型和强度对SWMM模型参数局部灵敏度的影响分析
|
摘要
运用修正的Morris筛选法对暴雨雨洪管理模型中水文水动力模块部分参数进行局部灵敏度分析,并研究降雨雨型和降雨强度对参数灵敏度的影响。研究结果表明,汇水单元不透水面积百分率(pct-imperv)对总径流量和峰值流量的灵敏度最高;对于总径流量,单峰降雨条件下的汇水单元面积(area)的灵敏度明显高于多峰条件下的灵敏度值;雨型相同时,增加降雨强度,下垫面参数的灵敏度增加。
The local sensitivity of parameters of hydrological and hydrodynamics modules in storm water management model(SWMM),was evaluated based on Morris screening method. Results showed that the most sensitive parameter to total runoff volume and peak flow was pct-imperv. Sensitivity of area to total runoff volume with unimodal rainfall was higher than it with multimodal rainfall. And sensitivity of underlying surface parameters increased when rainfall intensity increased.
