A local water table positioned above the regional water table is said to be: stranded perched displaced depressedGroundwater does flow through the High Plains Aquifer, but at an average rate of only 300 millimeters (12 inches) per day. The depth to the water table of the Ogallala Aquifer varies from actual surface discharge to over 150 meters (500 feet). Generally, the aquifer is found from 15 to 90 meters (50 to 300 feet) below the land surface. Simulating groundwater flow in a water-table (unconfined) aquifer can be difficult because the saturated thickness available for flow depends on model-calculated hydraulic heads. It is often possible to realize substantial time savings and still obtain accurate head and flow solutions by specifying an approximate saturated thickness a priori, thus linearizing this …An aquifer is filled with moving water and the amount of water in storage in the aquifer can vary from season to season and year to year.

Humans depend on rain to fill aquifers. Rain also plays a role in shaping the landscape and bringing nutrients to the ocean.These rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground. When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer.
