The impact of climate change on flash floods has become increasingly evident in recent years, with a notable increase in the frequency and intensity of precipitation, snowmelt, and alterations in atmospheric circulation patterns. As temperatures rise, atmospheric moisture retention increases, leading to a greater likelihood of extreme weather events. These processes have significant economic and social impacts on agriculture, infrastructure, and human life. The Black Sea Region and the Mediterranean basin in Turkey are particularly susceptible to the adverse effects of flash floods due to their geographical and climatic characteristics. The destructive potential of flash floods is amplified when they occur in the absence of robust local infrastructure. This study examines the mechanisms of flash floods triggered by climate change in detail. The study, which is supported by regional analyses and case studies, emphasizes the importance of sustainable land use, green infrastructure practices, and early warning systems in risk management. It is imperative that natural flood protection strategies and technological innovations be employed in order to minimize both environmental and human losses. The study posits that addressing climate change is not merely a technical matter, but also a social responsibility.
