A water table is a projection of lower masonry on the outside of a wall, slightly above the ground, or at the top of a wainscot section of a wall (in this case also known as a sill). It is both a functional and architectural feature that consists of a projection that deflects water running down the face of a building away from lower courses or ...
Below the water table, in the phreatic zone (zone of saturation), layers of permeable rock that yield groundwater are called aquifers. In less permeable soils, such as tight bedrock formations and historic lakebed deposits, the water table may be more difficult to define. “Water table” and “water level” are not synonymous. If a deeper ...
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
It measures 10 by 18 feet (3.0 by 5.5 m) across with a concrete water table, brick exterior walls, stucco cladding, and a belt course and frieze made of cast concrete. Similarly to the main house, the Spring House's walls slope inward above the frieze. In addition, there is a stair to the west and a doorway to the south. [317]
As a result of the high water table on the new site, the cathedral was built on foundations only 4 feet (1.2 m) deep. By 1258, the nave, transepts, and choir were complete. [12] As a result of being mostly built in only 38 years, Salisbury has by far the most consistent architectural style of any medieval English cathedral.
Static level is the level of water in the well when no water is being removed from the well by pumping. [8] Water table is the upper level of the zone of saturation, an underground surface in which the soil or rock is permanently saturated with water. [9] Well yield is the volume of water per unit time that is produced by the well from pumping. [8]

Construction below the water table is mostly managed by using cofferdams or pressurised caissons to exclude water sufficiently to work above the local water level within the enclosure, though it may also be possible to keep the water level down by pumping it out as fast as it seeps in, thereby artificially lowering the water table at the worksite.
