Abstracts This paper is concerned with a study on monsoon wave transmission at bamboo fences protecting newly-planted mangroves in the Lower Mekong Delta (LMD) of Vietnam. For this, new field experiments were carried out in combination with the use of an existing field dataset by Albers et al. (2013). In support of the analysis of the field data, influences of governing parameters on wave transmission are systematically examined using a numerical wave tank (i.e. a RANS-VOF model). It follows that the fence height is relatively more influential than the fence width. Also, high-frequency waves are generally more effectively dissipated by the fences than long-frequency waves. Importantly, the fence porosity is found to affect attenuation of both high- and low-frequency waves drastically, indicating its important role in the quantitative understanding of wave transmission as well as in the fence functional design. An empirical formulation of wave transmission at bamboo fences, needed for the fence functional design, was eventually derived from all the field data. As hinted at by the numerical analysis, the fence freeboard, the fence width and especially the fence porosity are found the major governing parameters.

湄公河下游三角洲保护红树林竹篱笆的季风波传输

摘要 本文研究了在保护越南湄公河下游三角洲 (LMD) 新种植红树林的竹篱笆上的季风波传播。为此，Albers 等人结合使用现有的现场数据集进行了新的现场实验。(2013)。为了支持现场数据的分析，使用数值波浪水池（即 RANS-VOF 模型）系统地检查了控制参数对波浪传输的影响。因此，围栏高度比围栏宽度影响更大。此外，高频波通常比长频波更有效地被围栏消散。重要的是，发现围栏孔隙度会极大地影响高频和低频波的衰减，表明其在波传输的定量理解以及围栏功能设计中的重要作用。围栏功能设计所需的竹围栏波浪传输的经验公式最终是从所有现场数据中得出的。正如数值分析所暗示的，围栏干舷、围栏宽度，尤其是围栏孔隙率是主要的控制参数。
