Experimental investigation of wave attenuation by mangrove forests with submerged canopies

Zhang, R. (author), Chen, Y. (author), Lei, Jiaxin (author), Zhou, Xin (author), Yao, P. (author), Stive, M.J.F. (author)

Mangroves can function as a ‘bio-shield’ to protect coastal communities from harsh environments because of their strong ability to attenuate wave energy. However, as mangroves are usually oversimplified as rigid cylinders in antecedent studies, the effects of complex mangrove morphology on wave attenuation have not been well researched....
