Salt water intrusion is the migration of saltwater into freshwater aquifers under the influence of groundwater development (Freeze and Cherry, 1979). The most detrimental effect of ground water depletion is the lowering of the water table. Saltwater intrusion also has an adverse impact on thee saltwater-freshwater interface. Methods for controlling intrusion vary widely depending on the source of the saline water, the extent of intrusion, local geology, water use and economic factors.
The proposed methodology of this study was to control saltwater intrusion through (ADR) Abstraction, Desalination and Recharge. The proposed methodology takes into account the interactions between the major parameters of an ADR system to control saltwater intrusion. These parameters include: soil/aquifer properties, well locations, well depths, and abstraction and recharge rates. An additional major parameter is the relation between abstraction and recharge rates. However, this depends on the recovery rate (the rate at which freshwater is rising in a bore) and salinity (the concentration of dissolved salts in seawater) of the abstracted water.
An ADR system is capable of completely preventing saltwater intrusion because it increases the volume of fresh groundwater and decreases the volume of saltwater, while considering economical aspects, environmental impact and sustainable development of water resources.
