Background

Groundwater refers to water present in the rock voids below the ground, and in the narrower sense, water in a saturated aquifer below the surface of the groundwater. In national standards, ground water refers to various forms of gravitational water buried beneath the surface of the earth. Foreign scholars consider that there are three definitions of groundwater: the first is all water buried in underground water which is obviously different from surface water, and particularly refers to the water of a saturated zone in a water-bearing layer; secondly, the water flows or permeates downwards to saturate soil and rocks and supply water to springs and wells; and thirdly, water stored in the cavities of the rock underground in the voids that make up the crust material. The groundwater is an important component of water resources, and is one of important water sources for agricultural irrigation, industrial and mining and cities due to stable water yield and good water quality. However, under certain conditions, changes in groundwater can also cause adverse natural phenomena such as swampiness, salinization, landslide, and ground subsidence.
