Hydrological Controls on Drip Water δ 18 O Heterogeneity: A 4‐Year Monitoring Study in Remi Cave, Southern China
Understanding how stable water isotopes are modified during percolation through the soil‐epikarst‐bedrock continuum is a fundamental challenge in karst hydrology, particularly in subtropical monsoon regions with heterogeneous infiltration dynamics. This study presents a four‐year (December 2020–December 2024) isoto...
