Jumna, the chief affluent of the Ganges, which it joins at Allahabad, rises in the Punjab, and flows through the North-West Provinces, having Delhi and Agra on its banks; its course is 860 m., and it falls over 10,000 ft.; its waters are used for irrigation by means of canals, being of little use for navigation.
