The study looked at how irrigation affects groundwater recharge in arid agricultural areas. They used chemical and isotope techniques to study the water sources contributing to groundwater. In these areas, most of the groundwater recharge comes from confined groundwater and river water, not from rain. The irrigation systems in place have changed how water moves underground, leading to a shift in the main sources of groundwater recharge. Without considering water leakage from irrigation, the contribution of lateral groundwater flow and confined groundwater would have been overestimated. This research helps us understand how to manage water resources better in dry regions.
