Confining layer definition
Confining layer means a stratum of impermeable or distinctly less permeable material stratigraphically adjacent to one or more aquifers.
Confining layer means a geological formation, group of formations, or part of a formation that is capable of limiting fluid movement above an injection zone. It is composed of rock layers that are impermeable or distinctly less permeable than the injection zone beneath it. There may be multiple confining layers above an injection zone.
Confining layer means a layer associated with an aquifer that, because of low permeability, does not allow water to move through it perceptibly under head differences occurring in the groundwater system.
More Definitions of Confining layer
Confining layer means that portion of an intervening zone that has sufficient areal extent and integrity to act as an effective impermeable barrier to the vertical migration of gases or other fluids into any strata or zones that contain protected water.
Confining layer or "confining formation" means a layer of low hydraulic conductivity material that significantly limits vertical movement of groundwater.
Confining layer means a body of low permeable geologic material that is located above or below one or more aquifers.
Confining layer means a geological material that restricts water movement relative to an aquifer. A confining layer includes:
Confining layer means a layer of natural earth materials having very low hydraulic conductivity that inhibits the movement of water into and out of a water bearing zone. A confining unit may consist of one of more confining layers.
Confining layer means a formation that serves as a barrier between water-, oil-, or gas- bearing formations.
Confining layer means all or part of a formation which impedes the flow of ground water from an adjacent aquifer.
