  • Descrição: Udaipur is located in the southern front of NE-SW oriented Aravalli hills. The area is dissected by several active fault/lineaments. To access the tectonic scenario, we have used a widely used conventional geomorphic indices such as stream length-gradient index (SL), asymmetry factor (Af), basin shape (Bs), valley floor width to valley height ratio (Vf), mountain front sinuosity (Smf), hypsometric integral (Hi), hypsometric curve, and transverse topographic symmetry factor (T) to analyze relative index of active tectonics (RIAT) of the Ahar watershed. Results of these geomorphic indices of each sub-watersheds are used to divide area from low to high tectonic activity classes. The results of relative index of active tectonic (RIAT) distribution pattern shows that the sub-watershed UDSW2, 3, and 4 is tectonically relatively more tectonically active than the other parts of the study area. The estimated results of RIAT distribution are well supported by the geomorphic evidences. The combined results of geomorphic evidences such as stream deflection and analysis of lineament and geomorphic indices reveal that the Ahar watershed of Udaipur district is most affected by tectonic activity.
