“…Faure et al (2002) have argued that as sea level dropped, exposing large areas of the continental shelf, the exit of groundwater from underground aquifers would have greatly increased because of the increased hydrostatic head and the removal of the overlying mass of seawater, which would otherwise tend to inhibit stream flow. Even today some water escapes from these underground sources onto the continental shelf in the form of underwater freshwater springs, and these are well known to local fishermen.…”

“…Even today some water escapes from these underground sources onto the continental shelf in the form of underwater freshwater springs, and these are well known to local fishermen. At lower sea levels, so Faure et al (2002) argue, the landscape of the emerged coastal plain would have been transformed into coastal wetlands. Hence, plant and animal distributions undergoing contraction in the hinterland because of increased aridity would have found new and more favorable territory into which to expand.…”

“…Forest clearance since about 5,000 years ago is likely to have resulted in increased recharge rates and enhanced the rate of Chalk permeability development (Hiscock and Lloyd 1992). Falling global sea levels during the last five glacial periods of the Pleistocene Ice Ages likely resulted in increased hydraulic heads in inland aquifers relative to those in the continental shelf, enhancing groundwater flow toward the coast (Faure et al 2002). Faure et al (2002) suggested that the "coastal oases" that formed from the groundwater discharge as springs along the exposed continental shelf had profound effects on biodiversity and carbon storage during periods of severe climatic stress.…”

Integrated Groundwater Management

Projected global change includes groundwater systems, which are linked with changes in climate over space and time. Consequently, global change affects key aspects of subsurface hydrology (including soil water, deeper vadose zone water, and unconfined and confined aquifer waters), surface-groundwater interactions, and water quality. Research and publications addressing projected climate effects on subsurface water are catching up with surface water studies. Even so, technological advances, new insights and understanding are needed regarding terrestrial-subsurface systems, biophysical process interactions, and feedbacks to atmospheric processes. Importantly, groundwater resources need to be assessed in the context of atmospheric CO 2 enrichment, warming trends and associated changes in intensities and frequencies of wet and dry periods, even though projections in space and time are uncertain. Potential feedbacks of groundwater on the global climate system are largely unknown, but may be stronger than previously assumed. Groundwater has been depleted in many regions, but management of subsurface storage remains an important option to meet the combined demands of agriculture, industry (particularly the energy sector), municipal and domestic water supply, and ecosystems. In many regions, groundwater is central to the water-food-energy-climate nexus. Strategic adaptation to global change must include flexible, integrated groundwater management over many decades. Adaptation itself must be adaptive over time. Further research is needed to improve our understanding of climate and groundwater interactions and to guide integrated groundwater management.

“…When the sea level falls, continental groundwater and surface runoff tend to adapt to the new base level, and water fluxes are deeply modified (Faure et al 2002, Faure andFaure 2004). The fall in sea level is accompanied by a retreat of the shoreline and, consequently, by a change in the location of existing springs; in addition, it leads to the location of new springs along the shoreline (Fig.…”

The increasing water demand is a concern affecting many regions in the Mediterranean Basin. To overcome this situation rim countries resorted during the last decades to a massive mobilization of their water resources, often resulting in excessive water exploitation. In such a context, understanding the effects of present recharge and aquifer salinization is crucial for correct water management. Understanding the present hydrogeological situation of coastal plains requires the knowledge of both their past morphologic conditions and their recent geological evolution. Within this framework, this paper presents a review of water related problems in the Mediterranean Basin. It suggests a conceptual model for groundwater resources in Mediterranean coastal plains, deriving from the present and past recharge processes. Special attention is paid to providing a better understanding of climate change impacts on water quantity and quality, and conservation of ecological diversity.Key words Mediterranean Basin; precipitation; present recharge; palaeoenvironment; palaeohydrology Influence des précipitations et des eaux salines profondes sur les systèmes hydrologiques des plaines côtières Méditerranéennes: un aperçu général Résumé La demande croissante en eau est un problème qui intéresse de nombreuses régions dans le bassin méditer-ranéen. Pour remédier à cette situation, les pays riverains ont fait appel à une mobilisation massive des ressources en eau, ce qui a souvent entraîné sa surexploitation. Dans cette situation, la compréhension de la recharge actuelle et de la salinisation des aquifères est cruciale pour une gestion correcte des ressources. Comprendre la situation hydrogéologique actuelle des plaines côtières nécessite la connaissance de leurs conditions morphologiques anciennes et de leurs évolutions géologiques récentes. Dans ce cadre, cette note présente une revue des problèmes liés à l'eau dans le bassin méditerranéen. Il est proposé un modèle conceptuel pour les eaux souterraines dans les plaines côtières de la Méditerranée, modèle s'appuyant sur les processus actuels et anciens de recharge de ces aquifères. Une attention particulière est accordée à une meilleure compréhension des impacts du changement climatique sur la quantité, la qualité des eaux, et la préservation de la diversité écologique.
