Abstract】In this paper, remote sensing techniques, as well as field studies, have been used to investigate the geomorphological processes and landscape evolution along the Saravan Fault, SE Iran to highlight how topographic features were influenced by active tectonics. Quantitative geomorphic analysis was carried out using mountain-front sinuosity (Smf), valley floor width – valley height ratio (Vf), drainage basin asymmetry factor (Af), Hypsometric integral (Hi), drainage basin shape index (Bs), mean axial slope of channel (MASC), standard deviation of topography (STD) and index of active tectonic (Iat). Remote sensing techniques, as well as field studies revealed that the Saravan Fault have three parts trending N-S, NW-SE, and E-W. Obtained results show that basins with high Iat index are located at where the strike of the Saravan Faults changes and where several strike-slip faults are crossed the Saravan fault.
