摘要
从以物理模型实验及理论解析为代表的植物消波研究手段与宏观和微观尺度下植物消波分析方法两个方面总结了国内外的研究现状和最新研究进展。对物理模型实验中的植物因子、水动力因子、植物模型制作和实验布置等要素以及理论解析模型进行归纳,分别阐述了以波高衰减和波能耗散为主要分析对象的植物消波分析方法,指出现有物理模型实验中植物几何比尺与波要素比尺难以统一和理论解析研究局限于二维情况等问题。综合考虑季节更替、植物摆动、波浪破碎、波浪随机性及非线性、潮流等因素是今后植物消波研究的重点突破方向。
Wave attenuation by coastal vegetation has attracted coastal engineers＇ wide attention. This study reviews present investigations and latest advances in typical approaches in laboratory experiments as well as theoretical analysis,as well as the analytical methods on micro and macro scales. Firstly,the governing parameters in vegetation modeling and theoretical models are summarized,such as those of vegetation,hydrodynamics and experiment setup in a laboratory experiment. It is revealed that the analytical methods can be classified into method of reduction in wave height and method of dissipation of wave energy,respectively. Finally,this paper points out that the scale effect in vegetation size and wave parameters is the main reason that limits the universal applications of analytical solutions,only applicable in 2-D flows. The further problems,coupling of multiple factors such as seasonality,motion of vegetation,wave breaking,the randomness and nonlinearity of waves,tidal currents,are desirable to be addressed.
