Seawater Intrusion in Coastal Aquifers

Kumar CP

Coastal regions are highly populated areas where more than two third of the world’s population lives. However, due to growing freshwater needs in these coastal areas, there has been indiscriminate and unplanned groundwater withdrawal. Due to over-exploitation of groundwater in these areas seawater has intruded into the freshwater aquifers. This phenomenon of seawater intrusion has become a widespread environmental problem of coastal aquifers.
