基于导向标准断面法的受冲淤影响洪峰水位预报模型

为有效解决受冲淤影响洪峰水位预报问题,以巴水流域主要控制站马家潭水文站为例,在分析水文站水位-流量关系特性的基础上,采用导向标准断面法建立了受冲淤影响的洪峰水位预报模型。实例验证结果表明,模型水位预报精度较高,能满足马家潭水文站预报精度要求,可以较好解决受冲淤影响洪峰水位预报的难题。

Forecasting model of flood peak water level affected by scour and silt based on guide standard section method

In order to effectively solve the problem of flood peak water level forecasting under the influence of scour and silt, taking Majiatan Hydrological Station as an example, the main control station of Bashui River Basin, based on the analysis of the characteristics of water level-discharge relationship of the hydrological station, a forecasting model of flood peak water level affected by scour and silt was established by using the guided standard section method. The results of case study show that the prediction accuracy of water level is high, which can meet the prediction accuracy requirement of Majiatan Hydrological Station and solve the problem of flood peak water level forecasting affected by scour and silt.
