Erosion and coastal planning in Las Toninas, Partido de la costa, province of Buenos Aires

Many coastal communities experienced dramatic growth by the end of 1970s, with the construction of high-rise condominiums, buildings, roads and related features on the ocean front. The purpose of this paper is to supply a new methodology of analysis for environmental impact evaluation in coastal are...
