The increased demographic and economic pressure on coastal areas has raised the demand for freshwater, causing over extraction in many areas and saltwater intrusion is a global problem affecting coastal aquifers. These pressures are increasing and may further be aggravated from the impact of climate change. It is required to establish a sustainable water extraction regime from coastal aquifers that do not exceed the natural (and artificial) recharge. One key to controlling saltwater intrusion is to maintain the proper balance between water being pumped from an aquifer and the amount of water recharging it. Constant monitoring of the salt-water interface is necessary in determining the proper management technique.
