The results such as decrease in agricultural production, product quality and change in diversity as
a result of drought create important socio-economic problems. For these reasons, it is becoming
an increasingly strategic study topic in academic circles. The fact that it is not observed instantly
like natural disasters makes it possible to take necessary measures on a basin basis in case of
drought. Accordingly, data obtained from meteorological stations in the Susurluk Basin were
used in this study. Within the scope of the study, the start and end dates and intensities of the
dominant dry periods were determined by using the Palmer Drought Severity Index (PDSI).
Using data such as precipitation, evaporation, transpiration and the water holding capacity of the
soil as inputs, a tool was developed in the R environment for PDSI and annual values were
calculated for each meteorology station by running all inputs in this tool. For the calculated PDSI
values, spatial and temporal analyze were made using the digital elevation model of the Susurluk
Basin using the ordinary cokriging interpolation method in ArcGIS 10.8 program
