Climatic geomorphology or the climatic morphology, cognition of the earth's surface, reviews the recognition of landforms affected by climate elements and factors. This branch of geomorphology concentrates on the distribution of landforms in relation to divisions of climatic regions on the surface of the earth. Yet, there have been no specific and detailed studies on automat classification of territorial units or regional morph climatic in Iran. In this research, the morph climatic regions of Kermanshah province were identified and classified by employing Gis-based cluster analysis technique (Iso cluster) and also using seven topo-climatic parameters (including: elevation, slope, annual precipitation, the average minimum Iran. temperature, absolute minimum temperature, number of days with temperatures below zero and the average annual temperature), as a result, five morph climatic regions and seven macro geomorphologic units have been identified. these areas include: Arid morph climatic zone (fluvial/aeolian), Semi-Arid (fluvial/slope movements), Semi- Arid (Pedimentation/fluvial), Cold (preglacial/fluvial), Very Cold (nivation/preglacial/Karstification).most area about 45% is related to Semi-Arid zone (Pedimentation/fluvial) and lowest area with 3.65% is related to Very Cold zone in Kermanshah province. Despite the capabilities of GIS and the model used automat methods for morph climatic classification have yet to be developed in Iran.
