摘要

Observations on the 2004 tsunami showed that coastal forest vegetation could reduce the impacts of a tsunami or a storm surge in two ways: (ⅰ) the well-known wave attenuation and (ⅱ) the protection of coastal areas from storm damage by stabilizing coastal sediments. In this paper, the wave damping performance of mangrove forest of different forest widths is systematically tested in Twin Wave Flumes (without and with the forest model in 1- and 2-m-wide wave flumes, respectively) for both regular and irregular waves. Results reveal that the dissipation coefficient increases with increasing forest width and is strongly related to the transmission coefficient as the contribution of the forest itself to wave reflection is negligibly small. The results also show that an increasing incident wave height causes the transmission coefficient to decrease due to stronger wave breaking. The wave energy dissipation through mangrove forest is also investigated theoretically and demonstrates a good agreement with the experimental results.
