1. Water table

   The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity.The groundwater may be from precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths, water fills in more of the pore spaces in the soils, until a zone of saturation is reached. 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. The water table should not be confused with the water level in a deeper well. If a deeper aquifer has a lower permeable unit that confines the upward flow, then the water level in this aquifer may rise to a level that is greater or less than the elevation of the actual water table. The elevation of the water in this deeper well is dependent upon the pressure in the deeper aquifer and is referred to as the potentiometric surface, not the water table.

1. water table

   The water table is the level below which the ground is completely saturated with water, also known as the upper surface of groundwater or the point at which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies beneath it from the unsaturated zone, known as the capillary fringe, or zone of aeration, that lies above it. Its level can vary depending on factors like rainfall, drought or the extraction of water from wells.

1. Water table

   a molding, or other projection, in the wall of a building, to throw off the water, -- generally used in the United States for the first table above the surface of the ground (see Table, n., 9), that is, for the table at the top of the foundation and the beginning of the upper wall

1. Water table

   The water table is the surface where the water pressure head is equal to the atmospheric pressure. It may be conveniently visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. However, saturated conditions may extend above the water table as surface tension holds water in some pores below atmospheric pressure. Individual points on the water table are typically measured as the elevation that the water rises to in a well screened in the shallow groundwater. The groundwater may be from infiltrating precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths water fills in more of the pore spaces in the soils, until the zone of saturation is reached. In permeable or porous materials, such as sands and well fractured bedrock, the water table forms a relatively horizontal plane. Below the water table, in the phreatic zone, permeable units that yield groundwater are called aquifers. The ability of the aquifer to store groundwater is dependent on the primary and secondary porosity and permeability of the rock or soil. In less permeable soils, such as tight bedrock formations and historic lakebed deposits, the water table may be more difficult to define.

Examples of water table in a Sentence

1. Ryan Zinke:

   We meet in the office, we go out to dinner, we talk about the background of the park. What are the neighbors like, what was the vision of the park, where the boundaries are, where the water table is because the water table has changed over time. What the railroad is. So they have the background.

2. Bill Weir:

   It was written after one of the wettest years ever, so all this water was over-allocated to the lower basin states, as a result, there has been this tension with New Mexico, Wyoming, Utah -- the upper basin states where all that snowpack has been diminishing. That was the water table for the Western United States, and now it's gone.

3. Craig Colten:

   There are very few basements in Louisiana, very few people live below, or even have a part of their house below the land surface, architecture and the local high water table -- which makes people not want to build basements and the fact that simply most houses are elevated, even with the same kind of rapid flooding that happened in New York Citys, if that had occurred in Louisiana, you wouldn't have seen the fatalities.
