Maintaining Fresh-Water Aquifers Over Saline Water in Coastal Aquifers

E.G. Youngs

Abstract


Seepage analysis is used to investigate the location dependence of fresh-water inputs and outputs in maintaining the depth of the fresh water over the saline water intruding from the sea in coastal aquifers in steady state conditions. Examples are given that show that maximum depths occur when the inputs are in the vicinity of the watershed and the outputs are near the coast.

 


Keywords


Saline water intrusion, coastal aquifers, steady state, Ghyben-Herzberg lens, groundwater abstraction, seepage.
