Özet
Today, mitigation of the adverse impacts of drought has gained considerable importance in the context of the management of water resources, which is adversely affected by climate change. In this context, to be able to achieve drought risk analyses, meteorological and hydrological data should be sufficient; if they are not, they should be completed. Seyhan Basin spread across the Seyhan River to an area of 2.203.544 ha, extending from Sivas to the Eastern Mediterranean. With 22.035 km2, the basin area constitutes 2.07% of Turkey's surface area. In this study, by using the meteorological and hydrological data of Seyhan basin between 1970 and 2016, drought risk analyses of the basin with the most widely used around the world SPI, SRI and SPEI drought indices were discussed. In first step of this study, incomplete data was completed with regional analyses. According to these indices, drought severity and magnitude were found. Analyses were performed according to 1, 3, 6, 9, 12, 18, 24, 48-month repeat intervals. Classification of droughts and threshold values were determined. The indices were compared, the correlation between them was examined, and drought risk analyses and drought maps were made separately for each index.
