The Quaternary [9.8] deposits are well-exposed along the entire course of the river and are represented by bouldery, pebbly or sand-pebbly gravels and associated sands, silts and clays. The alluvium has attained a thickness of about 20 to 25 m with a lateral extent of about 2 to 3 m especially in the middle and lower reaches of the river. The valley displays some unusual geomorphic features such as the appearance of infilled basin and entrenched meandering course. The valley has an appearance of infilled basin between Akola (19°32'; 74°01') and Sangamner (19°32'; 74°13') and the width of this basin near Sangamner is about 20 km. The river shows an entrenched meandering course in its first 25 km course, thereby indicating an uplift and the rejuvenated nature of its course. These unusual geomorphic features suggest the effects of tectonic movement of epirogenic type in the region.
