Background
Groundwater refers to water in a saturated aquifer below the surface of groundwater, and is a significant water body on the earth and has a close relationship with human society. The storage of underground water forms a huge reservoir in the ground, and the reservoir is an important water source for agricultural irrigation, industrial and mining enterprises and urban domestic water by virtue of stable water supply conditions and good water quality, and becomes an essential important water resource for human society, and especially in arid and semi-arid regions with water shortage on the ground surface, the underground water often becomes a main water supply source in the local.
According to different underground burying conditions, underground water can be divided into three categories of upper layer stagnant water, diving water and confined water. The water retention of the upper layer is a water storage body formed by the fact that the downward-seeping atmospheric precipitation stays in shallow rock cracks or sedimentary layers due to the local water-resisting effect. Diving is groundwater buried on the first stable water barrier below the surface of the earth, and it is most often seen that groundwater is diving. A spring is formed when groundwater flows out of the ground. The confined water (artesian water) is underground water buried deeply and existing between two water-resisting layers. Such underground water often has a large water pressure, and particularly when the upper and lower water-resisting layers are inclined, the water in the water-resisting layers is subjected to the large water pressure. When the well or the drill hole penetrates through the upper roof, the strong pressure can cause the water body to gush out, and the artesian water is formed.
Because the groundwater has stable water quantity and good water quality, the groundwater is one of important water sources for agricultural irrigation, industrial and mining and cities, but the change of the groundwater can cause unfavorable natural phenomena such as swampiness, salinization, landslide, ground subsidence and the like under certain conditions.
