Nerbud′da or Narba′da, an Indian river of about 800 miles, with a drainage of 36,400 square miles, rises on the Amorkantak plateau, 3,493 feet above sea-level, and flows west through the central provinces and the great channel between the Vindhya and Satpura Mountains into the Gulf of Cambay. It is navigable for only about 80 miles from its mouth. The Hindus consider it a sacred river and look upon a foot-journey from mouth to source and back as a meritorious act.
