Differential recharge to avoid salt water intrusion

Mon, 14/01/2013 -- engeology

Saltwater intrusion control systems perform an effective piezometric action especially when they are made up by a recharging barrier. This system can undergo a crisis along the coasts due to natural or anthropic factors, for example the tides and the waterways presence, able to skew the piezometry and thus making ineffective the barrier systems. As in most of the cases, this problem appears when the discharges that can be extracted or injected are very small: in many cases, the salt water intrusion goes on, particularly in most permeable layers. We would like to determine on the basis of recent experiences within which limits it is possible to obviate to the drawbacks deriving from this factor.
