Abstract

This study analyses morphological and geobotanical units along the Amapá coast, over the short term (~ 20 years), based on processing and interpreting optical and synthetic aperture radar (SAR) images, combined with data on water salinity, maximum flood height, sedimentary facies data, rainfall and river discharge. It is shown that the decrease in rainfall index during the drier period (1987-1997) is well-correlated with the reduction of the Calçoene River discharge and jointly with increasing tidal amplitude favored the increase of migration rate of the mud bank and erosion profile along the littoral. This was followed by the increase of the Calçoene River discharge and jointly with decreasing tidal amplitude during the wetter period (1997-2008), favoring the development of mangroves on muddy substrates near the coastline
