Coastal protection is critical for managing shoreline issues caused by the coast's continuous population growth. Coastal wetland ecosystems, such as mangrove forests, have been recognized for their ability to stabilize shorelines and protect coastal communities. Mangroves' high ability to store carbon, in addition to providing significant coastal protection, is currently receiving a lot of attention in the context of climate change. In this study, we’re interested to investigate the wave-damping phenomenon caused by mangroves, in general, using a modification of linear Shallow Water Equations. The model will be solved analytically using the separation of variables approach to obtain the wave transmission coefficient. Furthermore, the model is numerically solved using a finite volume on a staggered grid. We discovered that comparing the analytical and numerical results yielded similar results, implying that the numerical scheme can closely approximate the analytical solution. In addition to that, an allometric equation will be used to estimate the aboveground biomass of different mangrove species. Later, biomass estimates for mangroves can subsequently be converted to estimates of aboveground carbon using a standard multiplier. According to the simulation conducted in this study, the wave reduction is amplified as the friction coefficient and mangrove length increase. Meanwhile, among the different mangrove species, Rhizophora apiculata was found to store relatively more above-ground biomass and carbon as a consequence of its greater DBH, which is the standard for measuring trees. This suggested that Rhizophora apiculata can store a sizable volume of carbon and therefore can be the species to prioritize in mangrove preservation to mitigate climate change.
