MEDINA, Rubén Alberto  and  CODIGNOTTO, Jorge Osvaldo. Evolución del delta del río Paraná y su posible vinculación con el calentamiento global. Rev. Mus. Argent. Cienc. Nat. [online]. 2013, vol.15, n.2, pp.191-200. ISSN 1853-0400.

This paper discusses the recent geomorphological evolution of the Paraná River Delta on the basis of cadastral information, old topographic and nautical charts and satellite images. This evolution is linked to the consequences of global warming in the region of the Río de la Plata, particularly to the erosive processes. These processes are very active in areas close to the delta, especially in the Samborombón Bay. However, in the Paraná Delta not there was a decrease in their rhythm of progradation, on the contrary, it has remained constant or even has quickened. This is probably due to increased sedimentary load by the Paraná River in response to the increase of precipitation recorded since the 1970s in the region center and north of Argentina. As this is a direct consequence of global warming, or local climate variability, it may be said that the climate factor is also responsible for the aforementioned progradational dynamics.

Keywords : Paraná Delta; Evolution; Global warming; Río de la Plata; Samborombón Bay.
