Evaluación de los procesos antrópicos y naturales que inducen la removilización de un campo de dunas sobre la ruta provincial 11, provincia de Buenos Aires, Argentina

Abstract

On the Atlantic coast of the Buenos Aires province (Argentina), the development of coastal cities and infrastructures oriented to tourist activity presents different environmental problems that affects its natural dynamics. In this study, the anthropic and natural processes that originated the remobilization and intrusion of a dune field on Provincial Route 11 connecting the cities of Mar del Plata and Miramar were evaluated. Historical analysis of the degradation of coastal dunes were carried out with satellite images and GIS programs to quantitatively evaluate this process over time. In addition, geomorphological studies, plant censuses and grain size analysis of the remobilized sediments were carried out. It was found that the main factors of modification in the landscape have anthropogenic origin, requiring human intervention to mitigate the effects of the impact of the dune body on the route. A management plan that includes the fixation with vegetation of the front of the dune, as well as protecting and controlling the uses of the area covered by the dune system is proposed.
