Identification and Estimation of Groundwater Recharge Sources through Hydrochemical Analysis and Stable Environmental Isotopes in Evan Plain, Khuzestan, Iran
Identifying the inflows and outflows of plains experiencing groundwater level fluctuations is a critical aspect of water resource management, environmental decision-making, and agricultural planning. The rising water table in the Evan Plain, located in southwestern Iran, has resulted from various recharge sources, leading to significant challenges in the region. Thus, identifying these recharge sources and quantifying their contributions are essential for sustainable aquifer management. This study used hydrogeological, hydrochemical, statistical, and isotopic methods to identify and evaluate the recharge sources of the plain. Groundwater sampling was conducted during the dry and wet seasons (August 2022) and the wet seasons (May 2023). The results of hydrogeological assessments, hydrochemical analyses, hierarchical cluster analysis (HCA), and isotopic investigations reveal that the groundwater of the Evan Plain is mainly affected by two recharge sources. The Karkheh River, contributing an average of 30%, serves as the main recharge source in the northern and northeastern parts of the plain. Furthermore, The groundwater inflow from the Abbas Plain contributes an average of 32% to the aquifer recharge, predominantly affecting the plain's central, southeastern, and southwestern areas. These findings provide valuable insights for effective aquifer management and future regional water resource planning. The study highlights the importance of integrating multiple analytical approaches to enhance the accuracy of recharge source identification. Additionally, understanding these recharge dynamics is crucial for mitigating potential waterlogging and salinization risks in the region.
