Spatially Targeted Recharge and Water-quality Constraints for Conjunctive Management of the Kitab–Shahrisabz Aquifer

Spatially targeted groundwater recharge can significantly improve water management efficiency and quality in the Kitab–Shahrisabz aquifer, reducing river return flow by up to 50% and evaporation losses. The study identifies a 2.3-fold variation in infiltration-supply coefficients across tributaries, enabling more effective recharge placement. Four conjunctive management scenarios demonstrate that optimizing recharge placement, abstraction, and water-quality constraints can enhance storage-return efficiency to approximately 0.79 while maintaining water quality, particularly below a critical flow threshold of 2.0 m³ s⁻¹ in the Yakkabagdarya. This research provides actionable insights for sustainable groundwater management in piedmont aquifers.
