Laboratory model tests show that when the water table rises to the footing level, there can be an additional 400 to 500% of the settlements compared to when the soil is dry.Water table is the term for the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with groundwater, [1] which may be fresh, saline, or brackish, depending on the locality. It can also be simply explained as the depth below which the ground is saturated. Artificially lowering the water table was the primary method early European settlers used to drain areas with poor soil drainage for development and agriculture. This method is still used today by land managers and farmers to increase crop production in low-lying areas.

The maximum solubility of table salt (sodium chloride) in water at 20 degrees Celsius is 35.7 grams per 100 milliliters of water. The solubility of most solids increases as the temperature rises and decreases as the temperature lowers.

The water table on the control plots was naturally low, with a median water table (2006–2008) of 8 cm below the surface, and even lower during summer when respiratory activity was highest, with median values (C 1–3) between 11 and 19 cm below the surface.

Lowering of the water table in an unconfined aquifer leads to the release of water stored in interstitial openings by gravity drainage. Compared to gravity drainage, aquifer compression and water expansion in a water-table aquifer yield relatively little water from storage; hence, S y ≫ S s b and S ≅ S y in unconfined aquifers.Some time after the excavation, the groundwater table at rest will be reached. To guarantee a dry excavation pit, the groundwater table of the inflowing water can be lowered by continuous pumping with the aid of a dewatering system.
