摘　　要：针对河口近海越来越多的环境水力学问题,列举其数值模拟的工作步骤、内容和选择数学模型的原则,介绍数值模拟技术和经验,强调采用设计流场的必要性和计算成果合理性分析的重要性。具体讨论浓度(温度)场计算、海域事故溢油模拟以及工程水域泥沙冲淤预测的若干问题。Due to increasing numbers of problems relating to environmental hydraulics in inshore estuaries, the work stages, content, and principle used to choose the mathematical model for numerical simulation of water environmental problems are described. Technology and experience of numerical simulation are presented. It is increasingly necessary and important to adopt the design flow field and to analyze the reasonabihty of calculation results. Some issues are discussed, such as the concentration/ temperature field, simulation of oil spill accidents at sea, and prediction of sediment scouring in engineering projects.
