The Ganges River receives several important tributaries from the south as it flows across the Indo-Gangetic Plain. The two most prominent southern tributaries are the Yamuna River and the Son River.1

Additionally, the Tons River flows north from the Vindhya Range and joins the Ganges just below Prayagraj. While the Damodar River and Rupnarayan River are also associated with the river system, they specifically join the Hugli (Hooghly) River, which is a distributary of the Ganges.2
