摘要：
The aim of this work is to identify sediment deposition and erosion in coastal zones and to quantify the sedimentary budget in a beach-dune system of the Atlantic coast of Buenos Aires Province (Argentina) by a methodological framework based on GIS. Seven topographic survey campaigns were carried out from March 2016 to March 2017. The total volume of mobilized sand fluctuated between 31079 and 77680 m(3). A 488 m(2) area of permanent erosion was quantified, close to the coastline, and also an area of 2468 m(2) of permanent accumulation, mostly coinciding with the dune ridges. The identification of priority areas (3.7%) for remediation practices was performed. We recommended the installation of sand accumulation devices as possible alternatives for the remediation of the frontal dunes, mainly between March and June, since during these months the highest sediment volumes are present in the system.
