RT Journal Article T1 Consideraciones hidrogeoquímicas sobre el acuífero detrítico costero de Bou Ahmed (Marruecos) T1 Hydrogeochemical aspects about the detritic coastal aquifer of Bou Ahmed (Morocco) A1 El Attar, Aida A1 El Morabiti, Karim A1 Molina, Luis A1 Sánchez Martos, Francisco A1 El Kharim, Younes AB The salinity of the waters of the detritic aquifer of Bou Ahmed (Morocco) is very diverse. Based ontheir hydrogeochemistry, two types of water have been differentiated. The less saline group of waters(electrical conductivity less than 1.500 μS/cm) is directly related to the surface waters of the two riversthat feed the aquifer. The more saline group (1.000 μS/cm - 3.900 μS/cm) corresponds to sampling pointsalong the valley sides. Their greater salinity is a consequence of the longer contact time with the marlysandstones, which has allowed ion exchange processes to develop. In addition, waters have an elevatedHCO3- content as a result of the influence of a deep source of CO2 YR 2009 FD 2009 LK http://hdl.handle.net/10272/8026 UL http://hdl.handle.net/10272/8026 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
