Laboratory experiments on the effectiveness of mangroves to reduce tsunami energy were performed. A complex tree structure Rhizophora sp. was parameterized using stiff assumption (root system and trunk) for different submerged root volume ratios frontal areas. The hydraulic resistance prototype models under steady flow conditions compared most appropriate model in terms both equivalent practical feasibility selected further investigation. damping performance mangrove forest determined from laboratory tests performed synchronously a twin-wave flumes (with without 1 2 m-wide wave flumes, respectively) varying incident height solitary wave, water depth width. role types evolution modes is discussed based measurements forces exerted single along entire new approach transmission coefficient, which ratio trees placed last first row, proposed. In paper, important results parameterization procedure flume are discussed.
