Answer: Brahmaputra River
Notes: The Brahmaputra River flows south of Uzan Bazar in Guwahati. Uzan Bazar is one of the oldest parts of Guwahati and historically served as a river port on the Brahmaputra. The Barak River flows in southern Assam, separate from Guwahati, while the Manas and Subansiri are tributaries in the Brahmaputra basin but do not flow directly past Uzan Bazar.
