What is aquifer system.

A water table--or unconfined--aquifer is an aquifer whose upper water surface (water table) is at atmospheric pressure, and thus is able to rise and fall. Water table aquifers are usually closer to the Earth's surface than confined aquifers are, and as such are impacted by drought conditions sooner than confined aquifers. Learn more:The Edwards-Trinity aquifer, located in the Trans-Pecos and the Edwards Plateau areas, is composed of relatively flat-lying rocks that are generally exposed at the land surface.

Unconsolidated sand and gravel aquifers are characterized by intergranular porosity and all contain water primarily under unconfined, or water-table, conditions. They are grouped into four categories: basin-fill, blanket sand and gravel, glacial-deposit, and stream-valley aquifers. Semiconsolidated aquifers consist of semiconsolidated ...

The basic building blocks of shallow aquifer systems are clay, silt sand, gravel, cobbles and boulders. Since hydraulic conductivity is a measurable numerical characteristic of soil material, it was decided to define the stratigraphy of the shallow aquifer system using this characteristic of the stratigraphic units.
