Potentiometric surface - Wikipedia
A potentiometric surface is the imaginary plane where a given reservoir of fluid will "equalize out to" if allowed to flow. A potentiometric surface is based on hydraulic principles. For example, two connected storage tanks with one full and one empty will gradually fill/drain to the same level.

2019年10月16日 · The illustration shows an artesian well and a flowing artesian well, which are drilled into a confined aquifer, and a water table well, which is drilled into an unconfined aquifer. Also shown are the Piezometric surface in the confined aquifer and the impermeable, confining layer between the confined and unconfined aquifer.
Water Table Vs. Piezometric Surface | Healthfully
2017年7月27日 · The distinction between the water table and the piezometric, also known as potentiometric, surface is the difference between the naturally occurring surface of water in a groundwater aquifer and the surface of water in a monitoring well in a confined aquifer.
Manual on Subsurface Investigations - The National Academies Press
Water levels in wells or piezometers in a confined aquifer rise above the bottom of an upper confining layer (i.e., an artesian condition) and define a potentiometric or piezometric surface. An aquifer that has a water table as its upper boundary is unconfined.
How To Calculate The Piezometric Head - Sciencing
2020年12月27日 · Piezometric head represents the potential energy in groundwater from an aquifer. The equation for piezometric head includes elevation above a datum (usually mean sea level), pressure head and velocity head. Due to the slow velocity of groundwater, velocity head is negligible and generally ignored.
Piezometric Surface: Definition & Explanation - Vaia
2024年8月30日 · A piezometric surface is an imaginary plane where groundwater in an aquifer is at equal potential energy or hydraulic head, often coinciding with the level to which water will rise in a well.
Piezometric surface Definition & Meaning - Merriam-Webster
The meaning of PIEZOMETRIC SURFACE is the imaginary surface to which groundwater rises under hydrostatic pressure in wells or springs.
Piezometric Surface - DWS
Why is the piezometric surface important? The piezometric surface provides an indication of the direction of groundwater flow and is used to determine hydraulic gradients.
aquifer. The piezometric surface is an imaginary surface to which the water level would rise if a piezometer was inserted in the aquifer. Thus, it indicates the pressure of the water in the aquifer. Hence, a piezometric surface is the water table equivalent of the confined aquifer (see Figure -).
piezometric surface - Glossary of Meteorology
The imaginary surface that everywhere coincides with the piezometric head of the water in the aquifer.
