The aim of this study is to perform landform classification in the south of Isfahan, Iran. In order to make landform classification, Digital Elevation Models (DEMs) with 30 m resolution and Topographic Position Index (TPI) were used. Also, the percentage of each landforms classes in geomorphological units was determined. The results show that there were ten classes for the study area that consist of classes of canyons, shallow valleys, upland drainages, U-shaped valleys, plains small, open slopes, upper slopes, hills in valleys, midslope ridges and mountain tops. Also, the results show that the highest area of landform was for the classes of plain small for Playa unit. While for pediment unit, the area of landform was canyons, streams, U-shaped valleys, mountain tops and plains small. It was also determined that the highest area of landform for mountain units was mountain tops, canyons and stream landforms.
