The Motril-Salobreña aquifer is located in the Southern Andalusian coast, about 60 kilometres to the South of Granada. It is connected with the Mediterranean Sea in its south side, but also, it is located near Sierra Nevada, a very high mountain range with more than 3000 meters of altitude above sea level. A distance of only 30 Kilometres separates Mulhacen peak (3482 meters above sea level) from the coastline. The Guadalfeo River collects most of its water from the south face of this range, and conducts it to the Motril-Salobreña aquifer. The catchment of Guadalfeo River has an extension of more than 1200 km2.
