Las barreras hidrodinámicas negativas: un sistema efectivo para reducir la descarga de agua dulce al mar

Abstract

La necesidad de recursos hídricos para satisfacer las crecientes demandas es un problema generalizado, especialmente acuciante en las zonas áridas y semiáridas. Las zonas costeras son especialmente sensibles a este problema, si bien, en estas áreas se da la paradoja de que los acuíferos costeros, de forma natural, drenan grandes volúmenes de agua dulce al mar a través de la descarga submarina. En este trabajo se plantea, por primera vez, la utilización de barreras hidrodinámicas negativas como un sistema efectivo para reducir el volumen de estas descargas. Para ello, se ha estudiado el acuífero del delta del río Andarax, donde la presencia de una batería de sondeos que captan la cuña de agua salina que penetra en el acuífero, estaría actuando como una barrera hidrodinámica, que por un lado evita el avance de la cuña salina al continente, y por otro, la salida de agua dulce al mar. El problema que suscita este tipo de barreras es el coste económico ligado al consumo energético necesario para bombear continuamente agua salina, por lo que su uso sólo sería conveniente allí donde exista una planta desaladora que se abastezca de agua salina de la cuña que penetra en el acuífero.
