Abstract

This research investigates the impact of climate variability, with a focus on temperature and rainfall, on water levels in the Domasi River basin. Despite the absence of significant individual trends in temperature and rainfall, their combined effects contribute to the dynamics of water resources within the region. While temperature trends remain relatively stable and the correlation between temperature and water levels is not statistically significant, there is evidence of the potential influence of temperature variations on hydrological processes and water availability. Moreover, although no significant trend in rainfall amounts was identified, a robust positive relationship between rainfall and water levels highlights the critical role of precipitation in driving hydrological processes. These findings underscore the substantial impact of climate variability on water availability and river discharge in the Domasi River basin. Recommendations include the establishment of a robust monitoring system, investment in advanced hydrological modeling tools, community involvement in water conservation efforts, implementation of nature-based solutions, and collaborative efforts between stakeholders to develop adaptive water management strategies. Continued monitoring and analysis of climate data are essential for informing adaptive strategies for sustainable water resource management in the face of climate variability and change, not only in the Domasi River basin but also in similar regions worldwide.
