Question

How does a cone of depression form?

Answer 1

In the subsurface

Explanation:

When a well is operated faster, the steeper the gradient will be in the vicinity of the well. When a well is pumped, the water table in an unconfined aquifer, or the piezometric surface for a confined aquifer, forms a cone of depression in the vicinity of the well.

Under homogeneous and isotropic circumstances, you will see the radial flow (as aerial view). At the center of this system, the center of the well exists. When you move away from the well, you can measure higher water levels compared to that of the well.
