RT Journal Article T1 Contribución del contenido en tritio a la identificación del origen del agua subterránea: Sierra de Gádor (Almería) T1 Contribution of tritium content to identify the origin of groundwater: Sierra de Gádor (Almería) A1 Vallejos, Ángela A1 Pulido Bosch, Antonio A1 Molina, Luis A1 Sánchez Martos, Francisco A1 Gisbert, Josep A1 Martín Rosales, Wenceslao AB Tritium content of rainwater in Sierra de Gador has been higher than at. 10 TU during the last forty years.Groundwater samples apparently indicate the absence of recent contributions from the precipitation. The mixture with older waters stored inside the aquifer frequently hides the presence of modem recharge.From the content in tritium one can recognize two areas of preferential flow and recharge. One coincides with vulnerable basins to the generation of surface runoff and the other one is bound to a process of marine intrusion PB Sociedad Geológica de España YR 2001 FD 2001 LK http://hdl.handle.net/10272/9462 UL http://hdl.handle.net/10272/9462 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
