SE Español T1 Characterisation of the hydrogeologic domains individualized in the Sistema Mancha Oriental. SE Spain A1 Sanz Mangas, David A1 Martínez Alfaro, P.E. A1 Castaño Fernández, Santiago A1 Gómez Alday, Juan José AB Since 1969, hydrological studies have been focused on the evaluation of the water resources in the ManchaOriental aquifer. According to the water level records, some of them divide the system in several zones,which differ in number and extension. This fact leads to confuse calculations in the water balance. In thiswork, limits, geological structure, and water table evolution are described in the six hydrogeologic domains,which are identified taking into account not only the water level evolution but the geological features aswell. Their characterisation contributes to a better understanding of the hydrogeologic behaviour of asystem, which supports a high environmental pressure due to the development extensive irrigation cultures PB Sociedad Geológica de España YR 2005 FD 2005 LK http://hdl.handle.net/10272/8697 UL http://hdl.handle.net/10272/8697 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
