基于不同河道汇流方法的新安江模型研究
Research on the Xin'anjiang Model Based on Different Channel Flood Routing Methods
摘要
Abstract
In order to improve the accuracy of flood forecasting of Wuqiangxi Basin hydrological model the local inertial wave method is added to the Xin'anjiang hydrological model.The local inertial wave method is suitable for flood calculation in reservoir area without considering the inertia term of migration.In this study the characteristics of reservoir channel in Wuqiangxi basin are considered and the channel flood routing scheme based on segmented Muskingum method and the local inertial wave is established.The flood processes of Wuqiangxi Basin from 2020 to 2022 are selected for simulation and the results are compared with the traditional Xin'anjiang model.The results show that the segmented Muskingum method is still the simplest accurate and stable channel flood routing calculation method.However the confluence scheme based on the combination of the segmented Muskingum method and the local inertial wave method is innovative for the reservoir-type channel and has higher simulation accuracy which provides a new research scheme and route for the real-time flood forecast.关键词
