WEBA 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.

WEBConfined Aquifer Storativity. The storativity of a confined aquifer is defined as the volume of water released from, or added to, storage per unit change in head normal to the surface, per unit area. This is the same definition as for unconfined aquifers.

WEBIn most unconfined aquifers, the specific yield ranges from 10 percent to 30 percent. In other words, of the water held by an aquifer, 10 percent to 30 percent can be given up to pumping or other discharge. A coarse-grained aquifer will have a higher specific yield than a fine-grained one.

WEBThe term unconfined indicates there is free communication between the land surface and the water of the aquifer (Figure 44). These aquifers receive recharge from rainfall and melting snow; they are not overlain by a lower permeability unit that confines the movement of water within the aquifer.

WEBUnconfined aquifers are usually recharged by rain or streamwater infiltrating directly through the overlying soil. Typical examples of unconfined aquifers include many areas of coastal sands and alluvial deposits in river valleys. Confined aquifers are overlain by impermeable rock or clay. Unconfined aquifers are closer to the surface.

WEBThe simple aquifer shown in Figure 6 is termed an unconfined aquifer because the aquifer formation extends essentially to the land surface. As a result, the aquifer is in pressure communication with the atmosphere. Unconfined aquifers are also known as water table aquifers because the water table marks the top of the groundwater system.

WEBFeb 6, 2024 · In an unconfined aquifer, the water level in a well will be located at the top of the aquifer, which is the water table. Such a well is referred to as a watertable well. In a confined aquifer, the water level in a well will rise above the top of the aquifer.

WEBunconfined aquifer. confined aquifer. aquifer, in hydrology, rock layer that contains water and releases it in appreciable amounts. The rock contains water-filled pore spaces, and, when the spaces are connected, the water is able to flow through the matrix of the rock. An aquifer also may be called a water-bearing stratum, lens, or zone.
