cone of depressionCone shaped depression occurring horizontally across a water table. Causes by excessive removal of groundwater by a surface well.
|
2 |
cone of depressionA downward distortion or dimple in the water table that forms as a well pumps water faster than it can flow through the aquifer.
|
3 |
cone of depressionThe area around a discharging well where the hydraulic head (potentiometric surface) in the aquifer has been lowered by pumping. In an unconfined aquifer, the cone of depression is a cone-shaped depre [..]

cone of depressionA depression in the water table that develops around a pumped well.

cone of depressionThe depression, roughly conical in shape, produced in the water table by the pumping of water from a well. Confluent Growth

cone of depressionIn hydrologic terms, the depression, roughly conical in shape, produced in a water table, or other piezometric surface, by the extraction of water from a well at a given rate. The volume of the cone w [..]

9 |
cone of depressionthe drop in the water table near an overused well, resulting in a cone-shaped dry zone called an area of influence.

10 |
cone of depressionA depression in the water table that develops around a pumped well.

11 |
cone of depressionThe depression, roughly conical in shape, produced in the water table by the pumping of water from a well. Also called the cone of influence. Also see CIRCLE OF INFLUENCE.

12 |
cone of depressionIn hydrologic terms, the depression, roughly conical in shape, produced in a water table, or other piezometric surface, by the extraction of water from a well at a given rate. The volume of the cone will vary with the rate of withdrawal of water. Also called the Cone of Influence.
|
13 |
cone of depressionthe cone-shaped area formed when the spaces in the rock or soil are emptied as water is withdrawn from a well.
|
14 |
cone of depressionThe area around a discharging well where the hydraulic head (potentiometric surface) in the aquifer has been lowered by pumping. In an unconfined aquifer, the cone of depression is a cone-shaped depression in the water table where the media has actually been dewatered.
