Dorungar River Basin is located at Koppet Dagh Mountains in the north of Khorasan Razavi. Basin. Geomorphologic evidences show the continuousness of neo-tectonic activities in the Polio-Quaternary era. The purpose of this study is to evaluate active neo-tectonic area and to compare the results of geomorphic index and geomorphologic evidences such as Modern fault escarpments, lack of foothill, premorse and translocation alluvial fan, drainage basin asymmetry in Dorungar River, rejuvenation terrace and river and its influence on the river drainage network. The study used Landforms’ field visit, geomorphic index (Hi, Bs, AF, Smf, S, VF and SL), IAT classifying indices, topography & geology maps, Remote sensing images and Dem to analyze the neo-tectonic activities in the area. Results showed that the data acquired by geomorphic index and analyzed Geomorphologic evidence, proves that neo-tectonic in the area is active; and based on IAT classifying indices, the area is one of the active area neo-tectonically.
