Water sand belt refers to an area between groundwater and surface water, which is usually composed of sediment and aquifer, and has high Groundwater recharge capacity. The water sand belt can be considered as a highly permeable groundwater system composed of substances such as sand, gravel, and pebbles.


The formation of water sand belts is usually due to the uplift and erosion of mountain ranges, which transport materials such as sand, gravel, and pebbles to plain areas and deposit them underground. The gaps between these substances are filled with water, forming a reservoir of groundwater, known as the water sand belt.


Water sand belts play an important role in groundwater resources. It is an important foundation for the survival and development of humans, animals, and plants. The characteristics of water sand belt are abundant water quantity, good water quality, and stable water flow, suitable for development and utilization. Therefore, the water sand belt plays an important role in groundwater exploitation and protection.


In the process of mining water sand belts, it is necessary to consider that it will not affect the supply of groundwater resources and the environment. Therefore, sustainable methods must be adopted for water sand belt mining. At the same time, in order to protect the water sand belt, strict supervision and management systems need to be established to limit unreasonable groundwater extraction and prevent waste and damage to water resources.
