    Sir, in this DNS video you asked us to to prepare a list of Indian rivers along with their origin, end, states they flow through, dams and project built on it, waterfalls located on it, the left & right bank tributaries of it and many others. while preparing the notes for the same, many sources on the net provides that Left bank Tributaries of Cauvery are :- Lakshmantirath , Kabini ,Suvarnevati , Bhavani , Noyil , Amravati and the Right bank Tributaries of Cauvery are :- Hemavati , Shimsha , Arkaveri , Chovrai , Turunananimuttai. This info is contradictory to what you explained in the DNS video dated 31-03-20. Please correct me if i am wrong.
