Apr 20,  · Seawater intrusion in coastal aquifers. The exploitation of coastal aquifers always produces a lowering of the water table levels which are protected by the effects in the coastal strip of the sea level. When the extracted volumes are greater than the recharge, even on a local basis, a salinisation process begins in the aquifer as the. Saltwater intrusion occurs naturally to some degree in most coastal aquifers, owing to the hydraulic connection between groundwater and seawater. Because saline water has a higher mineral content than freshwater, it is denser and has a higher water pressure. As a result, saltwater can push inland beneath the freshwater. Seawater Intrusion in Coastal Aquifers Concepts, Methods and Practices Editors J. Bear A. H.-D. Cheng S. Sorek D. Ouazar I. Herrera Kluwer Academic Publishers.

Rising of Sea Water Level. ►Caused by global warming, resulting in increase in the quantity of salt water putting pressure on fresh water aquifers. Change in Precipitation. ►Slower recharge rate to replenish the amount of fresh water in the aquifer, making it more susceptible to the inland movement of salt water.
