基于河网水动力学模型的珠江三角洲排涝调度设计

Design of The Pearl River Delta Drainage Regulation Based on Hydrodynamics Model for River Network

基于一维非恒定流的圣维南方程组,在节点水量严格平衡的基础上,结合防洪防潮排涝调度设计,对河网水动力学模型的闸泵入出流计算和河网节点设计进行优化。针对广州市番禺区蕉东联围排涝区的外江水闸和河道整治项目,探讨了河网概化方法、边界条件的确定和模型的输出。

Based on the Saint-Venant equations of one-dimensional unsteady flow, on the basis of node- flux strict balanced, and combing with flood and moist control and drainage regulation design, it optimizes pump works in-out flow calculation and node design of hydrodynamics model for river networks. It discuss- es the river network simplified method, boundary conditions and the output of the model in view of the outer river brake and channel improvement project of jiaodong lianwei drainage area in Panyu district of Guangzhou city.
