Zone of saturation

Zone of Saturation: The layer beneath the surface of the land containing openings that may fill with water.

zone of saturation - A subsurface zone in which all the pores or the material are filled with groundwater under pressure greater than atmospheric pressure. Sources: ...

zone of saturation: The soil or rock located below the top of the groundwater table. By definition, the zone of saturation is saturated with water. Also see water table.

Zone of saturation The space in the soil below the water table in which all the pores are filled with water. The water in the zone of saturation is groundwater. Zooplankton ...

The upper surface of the zone of saturation of groundwater above an impermeable layer of soil or rock (through which water cannot move) as in an unconfined aquifer. This level can be very near the surface of the ground or far below it.

Water Table: Upper surface of a zone of saturation, where that surface is not formed by a confining unit; water pressure in the porous medium is equal to atmospheric pressure (the phreatic surface).

Zone of Saturation The zone in which the functional permeable rocks are saturated with water under hydrostatic pressure. Water in the zone of saturation will flow into a well and is called ground water.

A land area in which water reaches the zone of saturation from surface infiltration, e.g., where rainwater soaks through the earth to reach an aquifer. This definition is in context to Environment. See more contextual defintions for Recharge Area.

Groundwater: Water occurring in the zone of saturation in an aquifer or soil. Water beneath the surface of the earth which saturates the pores and fractures of sand, gravel, and rock formations.

The process by which water is added to a zone of saturation, usually by percolation from the soil surface; e.g., the recharge of an aquifer. Source: Terms of the Environment ...

Groundwater table. The upper surface of the zone of saturation (all pores of subsoil filled with water), except where the surface if formed by an impermeable body. gpm. Gallons per minute. "H" ...

Perched aquifer: Localized zone of saturation above the main water table created by an underlying layer of impermeable material.

Water Table:  The upper surface of the zone of saturation; the upper surface of the groundwater.

aquifer discharge area An area of land where the zone of saturation is in direct contact with the ground surface. Discharging ground water may appear as springs, seeps, or in baseflow of streams.

recharge The process by which water is added to a reservoir or zone of saturation, often by runoff or percolation from the soil surface.

The movement of water through openings in sediment and rock that occurs in the zone of saturation. Groundwater Flow Velocity A measure of the direction and speed of Groundwater Flow.

Recharge Area: A land area in which water reaches the zone of saturation from surface infiltration, e.g., where rainwater soaks through the earth to reach an aquifer.
