The purpose of the study was to analyze the slope deformations of a dam reservoir by comparing digital elevation models (DEMs) produced before and after data sets. The DEMs were generated automatically from large format aerial images acquired in 2012 and Gokturk-2 satellite images acquired in 2018. Both DEMs were compared and analyzed to obtain slope deformations. The results showed that the reservoir waters affected the slopes and some displacements were seen clearly in northeast slopes of the reservoir. The slope deformations can be monitored accurately with the proposed approach, with a note on the ground resolution of the images, which affected the accuracy and the density of the DEMs directly. The methodology provided promising results for automatic, low-cost and practical monitoring for slope deformations in large mountainous regions.
