Vidisha is a city in central Madhya Pradesh, India. It is located 62.5 km northeast of the state capital, Bhopal. The name "Vidisha" is derived from the nearby river "Bais", mentioned in the Puranas.

The Betwa is a river in Central and Northern India, and a tributary of the Yamuna. It rises in the Vindhya Range (Raisen) just north of Hoshangabad (Narmadapuram) in Madhya Pradesh and flows northeast through Madhya Pradesh and Orchha to Uttar Pradesh. Nearly half of its course, which is not navigable, runs over the Malwa Plateau. The confluence of the Betwa and the Yamuna rivers is in Hamirpur district in Uttar Pradesh.
