Abstract: This study probed the existence of groundwater in a mineral concentration area, using high-density electrical and transient electromagnetic methods. Our objective was to understand the dynamic changes in groundwater resources accurately and support the development of a sustainable ecological environment in the Gobi Desert area. The study demonstrates that the combination of the high-density electrical and transient electromagnetic methods guides the hydrological drilling construction in this area effectively. It also provides a reference for the selection and application of geophysical exploration methods under similar geological conditions for future studies.
