摘要
为了解决潮汐河段的水流演算问题以及现有的河道水流演算模型只能模拟某一特定变量的问题,对双变量耦合模型进行参数概化,并选取全国范围内来源于不同水系的19个河段汛期作为洪水资料进行验证,将计算结果与马斯京根法进行比较,双变量耦合模型的确定性系数更高,模拟过程与实际水流过程的拟合程度更好,模拟精度较高.应用于实际流域后表明该方法可有效提高洪水预报精度.
In order to solve the problem of flow calculation in tidal reach and the problem that the existing river flow calculation model can only simulate a specific variable,a two-variable coupling model is presented and the parameters are generalized.19 river sections from different river systems in the whole country are selected as flood data to verify the flood data.Compared with the Muskingum method,the certainty coefficient of the two-variable coupling model is higher,the fitting degree between the simulation process and the actual flow process is better,and the simulation accuracy is higher.The application of this method to the actual watershed shows that this method can effectively improve the accuracy of flood forecasting.
