Abstract
A space-time study of the coastline of the island of Tierrabomba was performed by analyzing satellite images, aerial photographs and orthophotos for the period 1954-2013 provided by the Center for Oceanographic and Hydrographic Research Caribbean - CIOH. This tool was used as a System of Geographic Information Systems (GIS) for Georeferencing images and digitized shorelines, making a division of the island into five sectors to identify areas of erosion and accretion rate with their respective Annual change by End Point Method (EPR) and identification of flood zones by the projection of the increase in mean sea level with an increasing trend of 5.3mm+0.3mm yr-1 using a digital elevation model into the tool GIS data with LIDAR (Ligth Detection and Ranging). It was observed that the general trend of the shoreline is eroding with accretion areas generated by anthropogenic craft works developed by the natives, the maximum erosion rate was 2.22mts yr-1 in the sector "Charlie" (northern Island) and the maximum accretion was 1.31mts yr-1 in the sector "Delta" (east side of the island) industry for a total of 52.5 and 10.1 Ha eroded accretion during 1954-2013. The areas identified as flood zones by increasing the mean sea level coincided with marshes and coastal lagoons that the natives of the region called "Salinas". each proposed scenario. The dynamic regionalization of the island of Santo Domingo allowed to identify surface mesoscale oceanographic structures as eddies and filaments for the month of February 2005.
