珠江三角洲潮汐河网水环境数学模型评述

对珠江三角洲潮汐河网水环境数学模型研究进行了系统的总结。结果表明：该河网地区一、二、三维水动力与不质数学模型在稳定性、收敛性及模拟精度方面已取得重大进展,而且提出了解决非线性项影响、河断面概化、潮汐动边界、自由表面非恒定运动以及不同维度模型之间的相互连接等难题的有效方法,但同时存在计算机耗时较多的缺点;在潮汐河网随机水质模型、污染物总量优化分配模型和区域水污染控制优化规划模型等方面也开展了探索性的

Evaluation of mathematical modeling techniques for tidal river networks on Pearl River Delta

In recent years, prompted by the urgent need of water pollution control, scientists and engineers on the Pearl River Delta have developed a series of flexible, accurate, and easy to use mathematical models especially suitable for tidal river networks; at the same time many new concepts and new techniques with academic as well as practical values have been advanced. Publications and international on line search demonstrates that the successful modeling of the Pearl River Delta has set an example for the simulation of complex tidal river networks. The purpose of this paper is to summarize these achievemens.
