Assessing Climate Change Impacts on Wadi Lakhdar Watershed: North Western Algeria
Synopsis
Climate change poses significant challenges to water resources management, particularly in arid and semi-arid regions like the Wadi Lakhdar watershed in northwest Algeria. This study investigates the impacts of climate change on the Wadi Lakhdar watershed from 1990 to 2010, focusing on efficacy rainfall and groundwater recharge dynamics. Utilizing a calibrated Global Conceptual Model Gardenia, we assess changes in precipitation patterns, efficacy rainfall, and groundwater recharge rates over the study period. Our findings reveal notable shifts in precipitation distribution and intensity, resulting in altered patterns of efficacy rainfall and groundwater recharge within the watershed. By integrating empirical data and modeling techniques, this research enhances our understanding of climate-water interactions in the Wadi Lakhdar watershed and provides valuable insights for sustainable water resources management in the face of climate change.
