Abstract

Groundwater resources provide the basis for the development of industry and agriculture. It also plays a role in promoting urbanization. Groundwater investigation and hydrogeological research in the Xinachuan Basin of the Huangshui River can provide a hydrogeological basis for the development of urbanization. This study takes the middle and upper reaches of the Huangshui Xinachuan River Basin as an example. Based on field investigation data, this paper passes through hydrogeological mapping, hydrogeological drilling, pumping test, sample collection and other work. The hydrogeological conditions in the middle and upper reaches of Xinachuan River have been basically identified. Zone the loose rock pore water-rich section of the river valley. It is calculated that the amount of water inrush is greater than 5000m³/d. The degree of mineralisation is less than 0.5g/L. Excellent quality and abundant quantity. It can be used as urban drinking water and farmland irrigation water.
