考虑海岸植被影响的水沙动力数学模型研究进展

Review on Hydrodynamic and Sediment Transport Numerical Models Considering Effects of Coastal Vegetation

摘要:

介绍了植被模型的不同考虑方式，分别从水流阻力、床面阻力、植被消长等方面展开讨论。基于工程尺度和实验室尺度水沙动力数学模型的研究，综述了植被影响下的流速、紊动能、拟序结构，不同波浪形态的传播特征以及悬沙浓度、地形演变等相关的研究进展。结合大量数学模型研究，提出了未来的研究趋势。

Abstract:

Different consideration methods of vegetation model are introduced， which are discussed from water flow resistance， bed resistance， vegetation growth and so on. Based on hydrodynamic and sediment transport numerical models of engineering scale and laboratory scale， the research progresses in flow velocity， turbulent energy， coherent structure， wave propagation characteristics of different incident wave shapes， suspended sediment concentration， and morphological evolution influenced by vegetation are reviewed. Combined with a lot of numerical model study， the future research prospects are proposed.
