复杂河网非恒定流水动力模型研究
Research on Unsteady Flow Dynamics Model of Complex River Network
摘要
Abstract
Holly Preissmann format is used to discretize the Saint Venant equation system,and the Newton Raphson iteration is used to solve the river section matrix.By utilizing the connection conditions at different types of bifurcation points,supplementary equations are constructed to simulate the flood evolution process of complex river networks such as tree like and ring like structures.The connection and control conditions of hydraulic structures such as weirs,gates,holes,culverts,and pumps are set,and the hydraulic structures are coupled with the river network to simulate the operation process of hydraulic structures.This paper uses a flood process in the Panlong River Basin to validate the model,which can accurately simulate the complex river network flood routing process and can be integrated into a digital twin water conservancy platform.关键词
