[Characteristics and Significance of Stable Isotopes and Hydrochemistry in Surface Water and Groundwater in Nanxiaohegou Basin].

The Nanxiaohegou basin is a typical watershed in the gully region of the Loess Plateau, China. The stable isotopes of hydrogen and oxygen and the hydrochemistry of the surface water and groundwater in the region were characterized in this study. The interaction between the surface water and groundwater in the region was demonstrated based on stable isotopes and hydrochemical methods.
