What is surface water and groundwater

Groundwater is water stored under the surface of the ground in the tiny pore spaces between rock, sand, soil, and gravel. It occurs in two “zones”: an upper, unsaturated zone where most of the pore spaces are filled with air, and a deeper, saturated zone in which all the pore spaces are filled with water throughout the year.

Jan 17, 2011 · The water found on the surface of the earth, like water in the river or lake is known as surface water. The water that is trapped under the earth’s surface is the ground water. Surface water is exposed to evaporation whereas ground water is not. Ground water is normally used for household drinking, cooking and other activities. Groundwater level terminology. Groundwater level is a term that is used in a relatively loose way, normally referring to the level, either below ground or above ordnance datum, at which soil or rock is saturated. This is also referred to as the water table and represents the top of the saturated zone. Above the water table lies the unsaturated ...Groundwater is water that exists underground in saturated zones beneath the land surface. The upper surface of the saturated zone is called the water table. …The capture of surface water leads to the recovery of groundwater levels and helps limit flooding, a study has shown.
