摘要
Abstract
To solve the issues of low forecast accuracy in downstream river sites during flood simulation and forecasting,as well as the excessive amount of data required when using hydrodynamic model methods,a hydrological-hydrodynamic integrated model was established.This model was based on the distributed architecture model theory of different hydrological characteris-tics of underlying surfaces.By decomposing and simulating the runoff generation and confluence processes at various stages in the hilly and plain areas of the basin,the model achieved mutual feedback coupling through momentum and flux exchange at the interface.Using the Sanjiang Basin as the study area,a coupled model incorporating upstream hilly area hydrological mod-el,plain area hydrological-hydraulic model,and downstream Yangtze River hydraulic model was constructed.Calibration and validation of the integrated model for the entire basin were conducted using representative stations.Analysis of rainfall from 2016 to 2022 in the basin and validation of multiple floods with rainfall exceeding 100 mm demonstrate good accuracy in flood simulation with the coupled model.The results indicated that the hydro-hydraulic coupled model effectively improves the pre-diction accuracy in the plain river network area and enhances the flood dispatching capability of the entire basin without re-quiring extensive data.This model had strong reference value and can provide insights for flood simulation and prediction re-search in other similar basins.关键词
