potentiometric surface

potentiometric surface

A Dictionary of Earth Sciences | 1999 | | Copyright

potentiometric surface (piezometric surface) A hypothetical surface defined by the level to which water in a confined aquifer rises in observation boreholes. In practice, the potentiometric surface is mapped by interpolation between borehole measurements. As with the water-table in an unconfined aquifer, the slope of the potentiometric surface defines the hydraulic gradient and the horizontal direction of groundwater flow. See HYDRAULIC HEAD.
