AB  - Safeguarding water resources for society and ecosystems requires a comprehensiveunderstanding of hydrological fluxes within the Critical Zone, Earth's living skin where the atmosphere,hydrosphere, biosphere, and lithosphere meet. For decades, tracer‐aided mixing models have been used to trackwater flow paths through the Critical Zone, mapping the journey of water particles from atmospheric moisture togroundwater. Recent advances in novel tracer measurements and modeling methodologies offer new insightsinto hydrological partitioning within the Critical Zone, enabling improved quantification of water fluxes acrossscales ranging from microscopic to macroscopic. Advanced tracer‐aided modeling approaches enable morerigorous testing of assumptions and improved quantification of uncertainties. In this review, we (a) summarizestate‐of‐the‐art tracer and modeling techniques, with an emphasis on stable water isotope tracers, (b) synthesizeinsights emerging from new approaches, and (c) highlight opportunities to apply these methods ininterdisciplinary Critical Zone research.
