Studies on Numerical Modeling of Water Environment in the Yangtze Estuary-Numerical Simulation of Hydrodynamic Flows

本文基于沿水深积分的平面二维非定常流动数学模型对长江口拦门沙水深水航道工程对长江口水域流场的影响作了细致的数值模拟。模型率定和验证表明本模型稳定性好 ,可应用于工程计算。数值模拟结果表明长江口拦门沙深水航道工程对长江口水域的流场有明显的影响。

Based on the depth integrated 2 dimensional mathematical model, the numerical simulation of the effect of a deep water navigation channel project on the hydrodynamic flows is presented in this paper. The calibration and validation showed that the model is fairly stable and applicable for studying regulation projects in the Yangtze estuary. The computed results show that the flow field in the estuary changes significantly due to the project.
