CONFINING BED


Meaning of CONFINING BED in English

A body of "impermeable" material stratigraphically adjacent to one or more aquifers. It may lie above or below the aquifer. In nature its hydraulic conductivity may actually range from nearly zero to some value distinctly lower than that of the aquifer. In some literature, the term confining bed has now supplanted the terms Aquiclude, Aquitard, and Aquifuge. Also referred to as Confining Layer.
