Mangrove forests exist in intertidal areas of tropical zones and most are characterized by their complex root systems, which attenuates flow energy. Among the mangrove species, Rhizophora species is the most common one, representing approximately 90% of the world mangrove distribution (Ohira et al., 2013). In addition, this species is used in the majority of restoration projects. Rhizophora plants are characterized by their aerial roots, which form a network above the substrate. Although several studies have been performed in the last decade to characterize flow interaction with mangrove trees (e.g.: Zhang et al., 2015), there is still a lack of knowledge of the forces exerted on the trees and the attenuation produced under waves, currents and waves and currents flowing simultaneously action.
