Taking Yanhe as an example, the distinct transition point of flood season runoff time series by the impacts of human activities has been detected by way of mathematical statistics analysis. And meanwhile, based on the datum before distinct transition point, the forecast model is set up only with the data series before the distinct transition point. The difference between the value derived from the equation and the observed value is right the influence on flood season runoff induced by human activities.

以延河流域为例，采用数理统计方法推估获取人类活动影响下汛期径流时序的显著转折点，以显著转折点前的数据建立预测模型，对比分析汛期径流量的实测值与预测值，其差值即为人类活动对汛期径流的影响程度。

The model adopts continuity equation, diffuse wave model, and the Mannings equation for surface runoff routing, while uses the Green and Ampt infiltration theory and Darcys Law for subsurface runoff treatment. Uncertainty analysis incorporating Monte Carlo simulation and a Maximum Likelihood Estimation and Efficiency Coefficient is used to retrieve optimal parameter values and to estimate the confidence interval for the simulation results.
