[ES] El objetivo del presente trabajo es la prospección de recursos hídricos subterráneos en el extremo sureste del territorio saharaui, para paliar las necesidades básicas de la población nómada de la región, y a la vez evaluar la posibilidad de creación de nuevos asentamientos en el área. El trabajo es el primero de carácter geológico, estratigráfico, geofísico e hidrogeológico que se lleva a cabo en la zona. Mediante los trabajos de geofísica se ha podido detectar que en algunos lugares los valores de resistividad eléctrica aparente disminuyen hasta profundidades superiores a los 50 metros, abriendo una puerta a la posibilidad de encontrar agua en cantidad suficiente especialmente en zonas de fracturas profundas. Los lugares preferentes para emplazar captaciones son los abanicos aluviales, las sabkhas y fondos de valle sometidos a fracturación. Queda por delante un amplio campo de investigación cuando se den las condiciones políticas estables que permitan una investigación con mayor detalle.
[EN] The aim of this work is the exploration of groundwater resources in the southeastern corner of the Sahara territory to alleviate the basic needs of the nomadic population of the region, and also assess the possibility of building new settlements in the area. It is the first time a geological, hydrogeological and geophysical work in this particular area of the Sahara is performed. Electrical Resistivity profiles show low values of apparent resistivity deeper than 50 meters, opening the door to the possibility of finding sufficient water, especially in areas of deep fractures. Preferred areas where located boreholes are alluvial fans, sabkhas and alluvial valley with fracturing. It remains a vast field of research when political conditions allow proper investigation.
