This study presents the spatial distributions of stable isotopes for groundwater according to well depth and spring water across South Korea.
Based on correlation between spatial factors and the distribution map, we determined major factors affecting spatial distribution of isotopes in groundwater and its mechanism.
In this study, contribution of mountain block recharge was evaluated by a direct comparison of δ18O differences between spring water and multi-level groundwater well.
The results of this study are expected to be used as basic data for evaluating regional groundwater systems, and to provide estimates for data-poor regions to help identify the relationship between groundwater and other hydrological factors.
