What is the relationship between drawdown and the cone of depression associated with a pumping well?

Question

Quizplus · Accepted Answer

Drawdown is the distance between the original water table and the water level in the well, while the cone of depression is the depression or lowering of the water table around the pumping well. As water is withdrawn from the well, the water level around the well drops, creating a cone-shaped depression in the water table, with the well at the center of the cone. The drawdown is the distance between the water level in the well and the original water table, which is the top of the cone shaped depression. Therefore, there is a relationship between drawdown and the cone of depression associated with a pumping well, as the drawdown is a measure of the extent of the cone shaped depression.
