Assessment of Drought in the Cekerek River Basin with Satellite-Based Palmer Drought Severity Index (PDSI)

Abstract

Drought-related outcomes, such as a decline in agricultural production and crop quality and a shift in diversity, result in significant socio-economic issues. Therefore, drought monitoring is essential to boost agricultural output, safeguard the environment, and minimize financial losses in drought-prone areas. The fact that drought cannot be observed instantly like natural disasters makes it possible to take necessary precautions on a basin basis. In this direction, in this study, the Palmer Drought Severity Index (PDSI) was determined in the Çekerek River Basin with satellite-based data. According to the results obtained, extreme drought events were observed at all stations in May 2021. The highest number of extreme drought events occurred at Çamlıbel station (51 events). The number of extreme humid events varied between 2 and 15, and the highest number of humid events were observed at Çamlıbel (15 events) and Yeşilyurt (15 events) stations. The drought trend status of the basin was evaluated with Innovative Trend Analysis (ITA). According to ITA results, a decreasing trend was detected at Çekerek, Çamlıbel and Yeşilyurt stations. Overall, it was determined that the drought status of the basin tended to exacerbate according to satellite-based PDSI values.
