The study looked at how surface water and groundwater interact in the Imphal River Basin in Northeast India. By analyzing the water's chemistry and isotopic composition, researchers found that groundwater has different characteristics than surface water. They also discovered that groundwater in the basin is influenced by both discharge and recharge processes. The isotopic composition of the water suggests that it comes from modern precipitation. Overall, the study provides insights into how surface water and groundwater interact in the region, which can help in managing water resources effectively.
