The project aims to address the critical issue of groundwater depletion in Jordan, where groundwater constitutes approximately 61% of the total annual water demand. This vital resource is under threat from multiple factors including rapid population growth, climate change, and over-pumping. To effectively mitigate these challenges, the project proposes the utilization of comprehensive models that integrate various data sources and variables. By understanding recharge processes and quantifying changes in available quantities, these models will play a crucial role in safeguarding the quantity and quality of groundwater resources in the region.
