is the difference in hydrostatic pressure between two points divided by the distance between them
is the difference in hydrostatic pressure between two points multiplied by the distance between them
7. a perched aquifer is
above the regional water table and is underlain by a lens of impermeable rock which prevents the water from percolating further dowanwards
one currently being replenished by rainwater via a rechrage zone on the surface
8. an artsian basin is a large, synclinal confined aquifer under hydrostatic pressure and an artesian well holds water under hydrostatic pressure, which rises up the well on release
