Hydraulic short circuit (hydrogeology)

In hydrogeology, a hydraulic short circuit is understood to mean the exchange of water between superimposed groundwater levels via natural hydrogeological or anthropogenic openings (e.g. well bores, groundwater observation pipes) in the groundwater reservoir .

Because a vertical flow between the water-bearing layers can occur in groundwater observation pipes and wells without pumping, a separate borehole should be carried out for each groundwater storey, since the otherwise possible hydraulic short circuit can affect the water quality of the individual aquifers and contribute to accelerated well aging.
