摘要:
【目的】红树林作为一种新型生态式的护岸工具,其消波效应已成为海岸工程研究热点。本文对红树林根、茎、叶不同组成部分进行定量研究,进一步探究红树林对波浪的消减效应。【方法】采取定量概化的根茎叶植物模型,通过波浪水槽试验探究了红树林植被区沿程波高衰减机制。将Kobayashi等提出的理论模型计算所得的植被区沿程波高理论值与试验值进行对比。【结果】研究发现,由Kobayashi等提出的理论模型计算所得的试验波高衰减系数的范围分别为0.02~ 0.47。当入射波波长与植被区沿流向长度之比趋于1时,消波强度最弱。同时波浪在植被区衰减过程中出现了边界效应及波浪跃增现象,波高增量比的范围为0~ 13...
摘要(英文):
Objective: Mangrove forest has become a research focus due to its functions as a newly ecological protector of shorelines. In order to quantify research the root, stem and leaf of mangrove forest, this study aims to experimentally investigate wave height decay along the quantitative generalized vegetation patch with root, stem and leaf. Method: The wave height calculated by the formula of Kobayashi was compared with experimental data. Result: The results showed that wave damping factors ranged from 0.02 to 0.47. The wave attenuation was lowest ...
