RT Journal Article T1 Geometría, piezometría y parámetros hidráulicos de los acuíferos de la cuenca baja del río Loukkos (Marruecos) T1 Geometry, piezometry and hydraulic parameters ofthe aquifers ofthe Iower part ofthe Loukkos river basin (Morocco) A1 Bouhmadi, B. A1 Benavente Herrera, José A1 Cruz Sanjulián, J. J. AB The alluvial materials of the Loukkos river (Morocco) downstream from Ksar-El-Kebir present transmissivity values in the 10-3 - 10-2 m2/s range and storativity values of 10-4-10-3 . The adjacent Oulad-Ogbane conglomerate formation drains towards the alluvium and is characterized by Iower T and higher S values. The morphology of the potentiometric surface (April, 1992) shows a general downstream hydraulic gradient ofnear 0.2 0/00 and a well-marked conoid —extending over TO km2 and with its apex slightly below the sea level— induced by the Ksar-El-Kebir supply pumping. The geometry of the substratum indicates a depression —elongated in the NW-SE direction— in the OuIad-Ogbane zone where depths of50 m below the sea leve/ are encountered PB Sociedad Geológica de España YR 1994 FD 1994 LK http://hdl.handle.net/10272/18115 UL http://hdl.handle.net/10272/18115 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
