Floods and overflows are among the most common disasters in the world and in Türkiye. Many studies have revealed that the frequency of floods and overflows in Türkiye has increased. One of the areas where they occur frequently is the Eastern Black Sea Region of the country. In this study, it is aimed to analyze the floods and overflows occurring in the Eastern Black Sea Region. Digital elevation model, temperature, precipitation and flood-overflow data are the basic data of this study. The geological, geomorphological, climate, vegetation, hydrographic, soil and land use features affecting flood-overflow are evaluated in the study. Temperature and precipitation data of some meteorological stations located in the Eastern Black Sea Region were put to trend analysis with the Mann-Kendall method. Morphometric indices were applied to 21 basins determined by Geographic Information Systems, and spatial analysis of floods and overflows was performed. Areas with high flood-overflow intensity were determined using point and kernel density analyses. Non-parametric Mann-Kendall, Sen’s slope and Spearman Rho tests were used to analyze the trend of floods. According to the obtained results, it is seen that slope and aspect facilitate the formation of floods. Positive trends were detected in the stations that were checked, in the monthly average temperature and monthly total precipitation data. It has been determined that the ruggedness value in the basins is high. This situation increases the risk of floods and overflows, and that they tend to increase over the years. It has been observed that flood-overflow density is high in Trabzon and its surroundings. In order to reduce the effects of floods and overflows, necessary studies must be carried, taking into account the areas with high point and kernel density. Settlements in river beds should be evacuated, river beds should be cleaned regularly, and the possible effects of climate change must be taken into account in basin management.
