The 'piezometric surface' of a confined aquifer is the imaginary surface to which water rises in:
Choose the correct answer
All open channels at the surface
Piezometers (tightly cased observation wells) penetrating the confined aquifer — water level indicates pressure head
Only streams and rivers
Water table in adjacent unconfined aquifer
Correct Answer
B. Piezometers (tightly cased observation wells) penetrating the confined aquifer — water level indicates pressure head
Why is this the answer?
Piezometric surface (potentiometric surface): imaginary surface joining the water levels in tightly cased wells (piezometers) penetrating a confined aquifer. If piezometric surface is above ground level: artesian well (water flows without pumping). If below ground: sub-artesian (must pump but requires less lift than water table well of same depth). Confined aquifer is always saturated.
