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