Hydrodynamic model for complex flow in open-channel networks
摘要
Abstract
A hydrodynamic model for open-channel networks is established using the newly proposed junction-point water stage prediction and correction (JPWSPC) method, which treats backwater effects at the junctions. In the model, the Saint-Venant equations are discretized using the Preissmann scheme. The resulting equations are solved using the Newton-Raphson method. The model needs neither specific node-numbering nor setting up and solving branch equations. Thus the model is applicable to both dentritic and looped channel networks, and more robust and efficient.关键词
