Résumé
Drought is a long-term natural disaster. It can cause significant loss to the ecosystem from agriculture. Various methods are used to observe the drought and take precautions early. In this study, 33 meteorological stations in the Southeastern Anatolia Region were targeted to analyze drought using rainfall and temperature data. For this purpose, a drought analysis was carried out between 1960 and 2015 using Standard Precipitation Index (SPI), Erinc Index and De Mortanne Index. The 3, 6, 9, 12 and 24 month time scales of the SPİ time series were calculated. Generally, near-normal drought and moderate drought are observed more frequently in short periods (3-6 months), whereas time-period (12-24 months) is increased by very severe drought. The driest period was between 1971 and 1980, and the station where the drought lasted the longest was the Pervari station for all time changes. According to Erinç and De Mortanne Indices, where temperatures and rainfall data are used, Şanlıurfa is the most arid province. The driest station is Akçakale station.
