Abstract By identifying the spatial distribution of isotopic signatures and electrical conductivity of water samples at different sites along the river channel in the study basin, the recharge–discharge relationship between the surface water and groundwater can be clearly evaluated. In this study, spring water, surface water and shallow groundwater in the study area of the Huaishahe Basin in Beijing, China were sampled and analysed for dD, d18O, pH and conductivity in order to evaluate the characteristics of the spatial distribution of surface water and groundwater. Using a combination of the topographic characteristics of the basin, the runoff characteristics of the river network and the isotopic compositions of the water samples, spring water, surface water and shallow groundwater can be spatially delineated into four regions in order to evaluate the recharge–discharge characteristics.
