Đặc điểm thủy động lực học và tác dụng của rừng ngập mặn trong công tác phòng chống xói lở bờ biển và biến đổi khí hậu khu vực đồng bằng sông Cửu Long

Abstract

In recent decades, the protective role of intertidal wetland areas in general and particularly mangrove forests for coastal regions has been increasingly recognized. Numerous studies on the stabilization of coasts and the sustainable development of mangrove forests have been published. The wave and flow attenuation through mangrove forests has been documented as the critical hydrodynamic processes, shaping the erosion, accretion of the coasts, and mangroves' growth or degradation. Nevertheless, the understanding of the necessary conditions that a mangrove forest needs to grow healthy is still in its infancy, especially in the context of the link between the degradation of mangroves, coastal erosion, and the absorption of the flow and wave energy inside the mangrove forest. This paper presents some new concepts and approaches clarifying the connection and influences of different hydrodynamic processes on the evolution of a mangrove forest: tide, flow, and waves. The possible relationship between human interventions, the degradation of mangroves, and their effect on the acceleration erosion of the coast in the context of sea-level rise was also discussed
