Question

What's a cone of depression?

Answer 1

CONE OF DEPRESSION

Pumping from a well in a water table aquifer lowers the water table near the well. This area is known as a cone of depression. The land area above a cone of depression is call the area of influence. Groundwater flows towards the well into the cone of depression which can change the natural direction of groundwater flow within the area of influence around the well.

Cone of depression is formed under the well in an aquifer when the water is pumped out through well is more than the recharge. Size and shape of the cone of depression are influenced by the many factors such as pumping rate, amount of water in the aquifer, type of aquifer material such as sand and silt.

hope it helped you out

thanks
