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

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.
