Southeastern tributaries like the Kali Sindh and Parbati begin at the extreme south of the Vindhyas and flow north in deep valleys, forming a triangular alluvial plain at elevation of 240-270 m. Afterwards the Banas, a northwestern tributary of the Chambal draining the Aravalli Range, joins the Chambal after crossing the hills near Sawai Madhopur in southeastern Rajasthan.
