Abstract

The study area is located in the Pravara River Basin in the Western Deccan Province. Few previous studies postulated that badlands in the Western Deccan Upland Region owe their origin to the Pleistocene-Holocene climate change events. In order to evaluate the tectonic stability of the area which could have been an alternative explanation for their origin, few geomorphic indices, such as Mountain Front Sinuosity Indices (Smf), Basin Asymmetry (AF), Stream Length Gradient Index (SL index) and Valley Floor to Width Ratio (Vf) were calculated. Results indicate that the study area had been affected by moderate tectonism in the past. During some of the past tectonic events, lineament controlled "block or local uplift" have affected these areas, causing local drop in the base-level, hence promoting erosion along these points to form the ravines. It is suggested that a neotectonic interpretation of apparently randomly spaced badlands development in the Western Deccan is more probable than a paleoclimatic or anthropogenic interpretation
