|
|
Term
|
Definition
| Impermeable bed or rock (ex. silt and clay) that make a confined aquifer (which creates pressure, related to artesian wells) |

|
Term
|
Definition
| Indicates the flow of shallow ground water (flow goes from high elevation to low elevation) |
|
|
Term
|
Definition
| When a pumped well is drawing water faster than it can be replenished, it creates a "cone of depression" in the water table and a change in the ground water flow lines. |
