What is an artesian well? Explain how an artesian well works
What will be an ideal response?
An artesian well is a well or spring in which water rises above the elevation of the aquifer due to high pressure at the bottom of the well. These often occur in a confined aquifer recharged at high elevation. The water is flowing horizontally and when a well is drilled, rises up as a function of the elevation of the recharge area and the distance between the recharge area and the discharge point.
