Cone of Depression:
A Cone of Depression is formed where the water table sinks at an exact point because of heavy pumping. Due to this activity the soil particles in the ground has increased air space. when the water pumping rate is faster than the ground water flow than it results in drawdown of water table at the location of the pump to form a cone. This is called the cone of depression and the area just above this cone is called as the area of influence. The cone of depression formation is directly proportional to the rate of pumping of water from the...
