RT Journal Article T1 Deterioró de la calidad de las aguas subterráneas en el acuífero del Río Vélez en el período 1985-1994 (Málaga, España) T1 Groundwater quality deterioration in the River Vélez aquifer from 1985 to 1994 (Málaga, España) A1 García Aróstegui, José Luis A1 Cruz Sanjulián, J. J. A1 Hidalgo Estévez, Mari Carmen A1 Carrasco Cantos, Francisco AB The River Vélez alluvial and delta deposits constitute one of the most important detrital aquifers on the south bàsìh o f Spain, given that its development provides water for Urban comsuption and productive agriculture. The setting up of Vihuela reservoir in the higher basin has caused a decrease Of the aquifer recharge. In addition, the persistent drought and the increasing exploitation of aquifer resources have produced a fall in piezometric levels accompanied by groundwater quality deterioration. A rise on nitrate concentration and a progression o f saline intrusion are the main consequences o f this 1985-1994 evolution PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12872 UL http://hdl.handle.net/10272/12872 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
