The purpose of the study was to analyze agricultural drought in citrus areas of Seferihisar Kavakdere Plain by calculating
NDVI and SAVI values and the surface temperature. The results showed that NDVI and SAVI have negative correlations
with surface temperature during irrigation seasons, where significantly increased temperature and decreased rainfall
reduced moisture availability for plants. The correlation coefficients between NDVI and surface temperature are -0.893
for 2013 and -0.600 for 2014. The correlation coefficients between SAVI and surface temperature are -0.857 for 2013
and -0.783 for 2014. The combination of NDVI, SAVI and surface temperature provides very useful information for
agricultural drought monitoring and an early warning system.
