基于LH-OAT的推理公式法参数敏感性分析
Parameter Sensitivity Analysis of Reasoning Formula Method Based on LH-OAT Sensitivity Analysis
摘要
Abstract
In order to analyze the influences of confluence parameter m and average gradient J at different flood frequency on runoff simulation in regions without data,the LH-OAT sensitivity analysis is used to analyze the parameter sensitivity of reasoning formula method.Taking two different small basins in Gedong Ditch,Fangshan County,Shanxi Province and Xiabao River,Xiaoyi County,Shanxi Province as examples,the parameter sensitivity of reasoning formula method at different flood frequency are analyzed and the level of parameter sensitivity and change rule are determined to offer numerical reference for parameter rating of model.The analysis shows that the rank order of parameter sensitivity to flood peak value in reasoning formula method is m ＞ J,the sensitivities of m and J have a weak trend with the reduction of flood frequency,and the velocity change of two parameters with flood frequency is Vm ＞ VJ.关键词
