Hidrogeología de las barreras medanosas de la Provincia de Buenos Aires: vulnerabilidad al aumento del nivel del mar

Abstract

Las barreras medanosas de Buenos Aires han tenido un desarrollo urbano explosivo una vez que las dunas fijas fueron convertidas en dunas forestadas desde 1931. Las urbanizaciones balnearias originales de Villa Gesell, Pinamar y Partido de La Costa están sien-do imitadas por municipios en los que la disponibilidad del recurso es limitada y los condicionamientos geomorfológicos diferentes. Algunos acuíferos han sido explotados con diferentes resultados. Se presentan las experiencias bien conocidas de la Barrera Me-danosa Oriental (BMO) y se informan algunas diferencias reconocidas en la Barrera Medanosa Austral (BMA). La barrera medanosa de Patagones (BMP) es solo mencionada ya que no se conoce explotación significativa. La interfase entre el agua salada y dulce es oblicua en la BMO y se trasladará hacia el continente con el avance del mar. En cambio, la interfase de la BMA es horizontal y condicionada por la naturaleza salina de las rocas que la infrayacen. De acuerdo a las tendencias en los cambios de uso del suelo (crecimiento urbano) se pronostican los efectos del aumento previsto del nivel del mar.

The sandy barriers of Buenos Aires have had an explosive urban growth once the dunes were afforested since 1931. The original bathing villages of Villa Gesell, Pinamar and Partido de La Costa are today being copied by counties where the water resources are limited and the Geomorphology conditions different. Several aquifers have been exploited with different successes. The well-known documented experiences from the Eastern Sandy Barrier (BMO) are considered, while some different experiences from the Southern Barrier (BMA) are also reported. The Patagones Barrier (BMP) is only mentioned that there is no significant exploitation known. The interface between the marine salt water and the fresh water is oblique at the BMO and is expected to migrate with the sea level rise. Instead, the interface between salt and fresh water is horizontal and conditioned to the nature of the rocks beneath. According to these trends in the land-use changes (urban sprawl), the effects of the sea-level rise are forecasted.
