Intensive groundwater development since the late nineteenth century and mostly after the 1950s has dramatically changed its hydrological functioning. Groundwater quality has suffered from salinity increase due to the potash mining area in the centre of the basin and seawater intrusion, as well as agriculture, waste disposal, sand and gravel pit backfilling and leakages. A stricter management is reversing and improving the situation and thus preserving the role of the LLAS as a crucial factor for the water supply to the Metropolitan Area of Barcelona. Besides model-based groundwater quantity management and stricter rules to protect water quality, additional actions include artificial recharge and installing a barrier to halt seawater intrusion by injecting highly treated reclaimed waste water. A groundwater user community was created and plays an important role in moving towards a sustainable use.

La planificación hidrológica debe considerar esas interferencias, hacerlas compatibles y, si es posible, complementarias, dentro del respeto razonable a los valores naturales. Para establecer las relaciones entre los humedales y las aguas subterráneas, además de las redes de observación generales, hacen falta redes específicas diseñadas para captar las variables que tienen una influencia determinante. Esas redes deben considerar el carácter tridimensional del flujo del agua subterránea en las proximidades del humedal. Lo mismo vale para los estudios que se deben realizar y su detalle. En cualquier caso, se requiere un modelo conceptual de funcionamiento bien contrastado con ayuda de métodos hidrodinámicos, hidrogeoquímicos e isotópicos ambientales. Para la planificación y gestión pueden hacer falta modelos numéricos de flujo y transporte de masa, pero, en muchos casos, con cálculos sencillos se puede llegar a una buena aproximación cuantitativa en tanto no se realicen caracterizaciones más detalladas.

Ramón Abstract: Spain is a country with a large hydrogeologic potential. As in other southern European countries the water resources, besides urban supply, are used mainly for irrigation and much of the groundwater abstraction is concentrated in a number of intensively exploited aquifers. Groundwater was declared a public domain resource in Spain in 1985, but the real implementation of such a declaration has encountered many difficulties in practice. Because groundwater was a private property before the 1985 Water Act, it was not considered a task for water management agencies and water authorities in Spain. As with aIl the European Union Member States, Spain is nowadays fuIly involved in the process of implementing the principies of the European Water Framework Directive (WFD) (European Commission, 2000). Such a process constitutes a unique opportunity to improve groundwater protection and knowledge, and achieve effective management of this resource. However, to adapt the WFD principies to the hydro-climatic and socio-economic context of a south European Mediterranean country is not an easy task. The current papel' provides an overview of the hydrogeologic context and groundwater management practices in Spain. The main groundwater "facts and figures" of Spain are introduced first, mainly concerning the hydrogeologic knowledge and groundwater use in the country, with a section on specific technical measures. A summary of the groundwater management context is described afterwards, introducing the institutional and legal framework as weIl as sorne basic concepts related to groundwater management, and also a section on groundwater cost issues. Next, a section of discussion about the ongoing process of the WFD implementation in Spain is offered. This paper finishes with a general summary and some conclusions.
