Groundwater
Unconfined groundwater
Confined groundwater
The Water Table
Water Zones
Aquifers
How the connections between the pores or fractures control how water moves through an aquifer
Artesian Basins
Artesian Wells
Springs
1. A permeable rock lying on top of an impermeable rock in a hill
Spring Formation
2. Where the water table comes to the surface along the side of a valley.
Spring Formation
3. Where there are faults in the rocks, with the result that a permeable rock is brought up against an impermeable one.
Spring Formation
4. Artesian Spring
Spring Formation
5. Numerous springs occur where the junction of limestone rocks and underlying impermeable rocks meet the surface
