Kouhbanan fault is known as one of the faults that caused many seismic events in Iran. The aim of this study was to investigate the role of tectonics in the development and geometry of the alluvial fans adjacent to this fault. To achieve more accurate results some morphometric indices measured and analysed after considering various factors such as weather, catchment area, regional lithology, tectonic setting, roughness index and field survey. Accordingly, the alluvial fans that were most affected by tectonic were identified.
