英文摘要	In recent years, changes in precipitation caused by climate change resulting from global warming lead to great floods in world. This climate change causes drought in some regions, whereas it causes heavy rainfall in some other regions. Investigating the effects of large floods as a result of heavy rains is of great importance. Turkey is among countries affected by climate change as a result of global warming due to its location. Extreme rainfall has caused great floods in country. Although the effect of these floods cannot be phased out completely, it is important to establish flood models to minimize them. Being the third longest river in Turkey, Sakarya river frequently exposes town Geyve in Sakarya Province to floods. The occurrence of these floods can be affected by sudden and severe rainfall, as well as negative interventions made by people living in this region. Therefore, it is very important to model flood that may occur as a result of heavy rains in Geyve district of Sakarya river in study. In order to establish this flood model, first and foremost recurrence flows of 100 and 500 years will be determined, then digital terrain model will be prepared in ArcGIS software, and 1- and 2-dimensional flood dispersion maps will be established with Hec-RAS software. As a result of 1D and 2D flood analysis on Sakarya river, carrying capacity of river was found to be insufficient for flood flow rates Q100 and Q500. This insufficiency exposes local residents, social activities and recreation areas, D650 highway and high-speed railway to floods. © 2020, Springer Nature B.V.
