The upper surface of an area filled with groundwater separating the zone of aeration the subsurface region of soil and rocks in which the pores are filled with air and usually some water from the zone of saturation the subsurface region in which the pores are filled only with water. It forms the upper limit of deposits of groundwater and can go up and down based on a number of factors.
Water Table Wikipedia
The water table usually rises after heavy rainfall and the melting of snow and falls during drier periods.
What is water table. The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock. The soil surface above the water table is called the unsaturated zone. During the late winter and spring when accumulated snow starts to melt and spring rainfall is plentiful water on the surface infiltrates into the ground and the water table rises.
The zone of saturation is where the pores and fractures of the ground are saturated with water. A high water table is especially common in low lying areas or areas where the soil is not well drained. In order to be successful a well must be drilled into the zone of saturation.
The water table is the upper surface of the zone of saturation. The level at which the ground beneath the surface is saturated with water. Water pressure and atmospheric pressure are equal at this boundary.
The upper surface of the zone of saturation is called the water table. The water table is the point between the two zones at which the ground becomes completely saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure where gauge pressure 0.
The zone that exists between the water table and the ground surface is called the zone of aeration. The depth of your water table largely depends on the material that the earth underneath you is composed of and the amount of precipitation available. The water table lies underground and is the level at which the soil and gravel are completely saturated with water.
Whenever it rains water drains through the soil until it reaches the point in the earth that is saturated with water and moves no further. People often access it with wells since there is over 20 times more freshwater underground than on the earths surface. Water table also called groundwater table upper level of an underground surface in which the soil or rocks are permanently saturated with water.
The water table separates the groundwater zone that lies below it from the capillary fringe or zone of aeration that lies above it. The depth to the water table can change rise or fall depending on the time of year. There is often some seasonal change in the water table due to rain or drought.
