Water resource managers worldwide are grappling with significant challenges exacerbated by rising temperatures and decreasing precipitation due to climate change. This phenomenon intensifies the hydrological cycle, leading to drier dry seasons and wetter rainy seasons, which increases the risk of extreme floods and droughts. Drought, often seen as the most complex and least understood natural hazard, impacts more people than any other hazard, affecting nearly every region globally. The primary aim of this research is to analyze and develop interdisciplinary tools for drought characterization and improved water resource management during drought periods, using the Ruhr river basin as a case study. The study investigates climate change in the basin through a comprehensive dataset of precipitation, temperature, and inflow, all subjected to a detailed homogenization process. Yearly and seasonal trend analyses were conducted using the Mann-Kendall test, revealing a significant increase in mean temperature across all time scales. Warm days have increased in both winter and summer, while cold days have decreased. Precipitation analysis indicated a significant rise in winter precipitation, with summer and annual changes being statistically insignificant. The study also found trends of increasing very wet days in winter and significant increases in winter inflow, while summer inflow remained statistically unchanged. Correlation calcula
