WHAT IS WATER TABLE? HOW IS IT FORMED?

 

THE TOP LAYER OF THE UNDER GROUND SURFACED WATER IS CALLED WATER TABLE . THE PLACE WHERE THE WATER TABLE MEETS THE LAND SURFACE WATER MAY COME OUT OF THE SURFACE IN THE FORM OF NATURAL SPRING & FLOW INTO LQAKE, STREAM , OCEAN, ETC.......

The Water Table

The topmost level of groundwater is called the water table; below this level the soil is waterlogged. If a hole is dug deep enough in the soil, it may reach the water table. The water table is not at the same level everywhere. It may be close to the surface in some places and hundreds of feet beneath the soil in others. Sometimes a deep cut in the land will expose the water table. Then the groundwater runs off as a stream or river.

Changes in climatic conditions and in the amount of precipitation used by vegetation may cause the water table to rise or fall. Heavy rainfall can raise the water table. If the level becomes too high, damage can occur to plants. During times of sparse rainfall, the soil becomes extremely dry, and groundwater that seeps to the surface and evaporates is not replaced. The water table then becomes lower. If much of the lost water is not soon replaced, a drought may occur.

Water that is drawn from wells may affect the level of the water table in a given area. When groundwater is pumped to the surface, the water level in the well becomes slightly lower than the surrounding water table. Groundwater then flows downward to the level of water in the well, causing a cone of depression in the water table. This lowers the water table slightly. If water is rapidly drawn from a number of wells in the same area, the water table may be lowered considerably. The water table may rise again when sufficient rainfall occurs or when there is a decrease in the amount of water taken from wells.

The water that is found under the surface of the Earth and is responsible for the presence of water in the wells, tube wells, and springs is called ground water. The porous regions in the soil and gaps in between the rocks are filled with this ground water. The upper limit of this layer of ground water, which fills into all the porous spaces between the soils, is called the water table.

The water table is the level of groundwater.When it rains the water seeps down and gets deposited above the bed rock.This water is then taken out by wells and tubewells and used for various activities
