Short summary
We studied how rivers and groundwater interact in an arid region of Northwest China, where water is scarce and vital for farming. By analyzing the chemistry and natural markers in water samples, we found that the connection between river water and groundwater changes from mountains to plains. These findings help explain how water moves through the region and offer guidance for managing water resources more sustainably.
