Abstract: Climate change poses a significant threat to watershed hydrology by altering precipitation patterns, increasing evaporation rates, and disrupting water availability. This paper investigates how climate variability affects streamflow, groundwater recharge, and surface runoff within watershed systems. By integrating case studies, hydrological models, and observed data, the paper evaluates potential future scenarios and highlights adaptive strategies for sustainable water resource management. The findings underscore the importance of revising watershed planning approaches in light of changing climatic conditions to maintain ecological balance and ensure water security.
