| 对近年来国内外浅水流动及输运三维数学模型的发展作了较全面的回顾，重点论述了数学模型研究中的若干基本问题，包括垂向坐标的σ变换、悬沙输移的近底边界条件、自由水面的计算、紊流的封闭问题以及有效的数值计算方法。讨论了浅水流动及输运三维数学模型有待于进一步研究的方向和发展趋势。 |
| 英文摘要: |
| A comprehensive review on the development in 3-D mathematical model of shallow water flow and sediment transportation is presented.The basic issues such as the σ-coordinate transformation,the near-bed conditions for suspended sediment transport,the computation of water surface,the turbulence closure model and some efficient numerical methods involved in developing a 3-D mathematical model of shallow water flow and sediment transport are discussed.The problems pending for solution and the trend of development are introduced. |
