چکیده

Enhanced deposition is common near river mouths where large amounts of sediment available. Our study focuses on the effects a mangrove forest in Mekong delta, Vietnam. At this site, fringe characterized by Sonneratia spp. and both mud sand are present. High rates bury roots pneumatophores, causing dieback. Field measurements indicate that dead trees ghost have buried about 1.20 m sediments, while surviving typical root depth 0.6 m. Saplings revegetating dieback area around 0.2 Root further related to basal number pneumatophores per square meter. Sediment burial covers smothering mangroves decreasing health forest. Remote sensing images occurred 2014, with sharp drop Normalized Difference Vegetation Index (NDVI). The partly recovered following 5 years reaching NDVI value 2013. adding new understanding coupling between evolution transport tropical deltas.
