This research aimed to investigate the spatial context of the Mae Rim River Basin, study the types of geomorphologies and classification caused by the fluvial process of the Mae Rim River, and create a geomorphology map of the study area. The study area is located in Mae Rim River basin in Saluang Sub district, Mae Rim District, and San Pa Yang Sub district, Mae Taeng District, Chiang Mai Province. Topography was analyzed using 30-meter SRTM 1 Arc-Second Global high-level numerical model data. Then the Topographic Position Index (TPI) was calculated using SAGA GIS. The results showed that more than 60% of the studied areas are mountainous and hilly terrain. Its sloping towards the east. The elevation is from 340 - 1440 meters above sea level. Most of the rock units are sedimentary and metamorphic and igneous rocks. The sediments of the riverbeds and the stream sediments were found in the eastern plain. The main river is the Mae Rim River. In terms of geomorphology, there are 10 types of geomorphology, including areas of open slope, plains, mild slope ridges, mild slope drainages, valleys, upper slopes, high ridges, streams, upland drainages, and local ridges.
