Atmospheric precipitation seeps into the ground and flows along the inclined direction of the rock stratum. When blocked by intrusive rock mass, confined water gushes from the surface to form spring water.
Spring water provides an ideal water source for human beings, and can also constitute many ornamental landscapes and tourism resources, such as physiotherapy springs and drinking springs. There are countless springs in China, which are widely distributed and rich in types, and there are countless famous springs everywhere.
According to the different flow conditions, the extended data can be divided into geysers and regular springs. If there is no obvious water flow after groundwater emerges from the surface, it is called seepage.
According to the temperature of water flow, spring water can be divided into hot spring and cold spring.
Spring water can be divided into eight grades according to its flow. The flow rate of the primary spring exceeds 65,438+000 cubic feet (2,800 liters) per second, the flow rate of the secondary spring ranges from 65,438+00 to 65,438+000 cubic feet per second, and the flow rate of the eighth spring is less than 65,438+0 pints per minute.
