Dynamic Modeling of the Groundwater System in Hamedan – Bahar Aquifer

The growing number of areas facing to water scarcity necessitates adaptive water management strategies beyond traditional water supply and demand management methods, which are becoming increasingly difficult in many regions. Water reallocation offers a flexible water management approach to mitigate water scarcity under changing socio-economic, climatic, and environmental conditions. This study develops a complex system dynamic model (SD) reflecting interactions between water resources, Environmental water demand and socio-economy using SD software package ‘‘Vensim PLE’’. Four alternative socio-economic growth patterns and three alternative schemes are designed to simulate those impacts. The results reveal that the developed SD model reflect the dynamic behavior of the system in the studied area efficiently. In the meanwhile, by comparing the different scenarios, it can be found that a higher growth pattern with desirable scenario supply socio-economic growth and environmental water requirements. It should be explained that the maximum growth pattern allows policy makers to revive the aquifer balance by controlling demand and adopting methods such as increasing artificial aquifer feeding and purifying treatment of urban and industrial wastewater.
