Abstract

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 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.
