The topography of Dibrugarh is overwhelmingly that of a riverine floodplain. The city sits at an average elevation of 108 meters (354 feet) above sea level. The terrain is remarkably flat, characteristic of the Brahmaputra Valley, with very little natural variation in elevation within the city limits.
To the immediate north lies the active floodplain of the Brahmaputra River, bounded by a vital protective dyke. South and east of the city, the land transitions into gentle, rolling plains covered by sprawling tea estates. There are no major hills or mountains within the city itself, though the majestic Himalayan foothills in Arunachal Pradesh can be seen on the horizon on clear days. The lowest points are the riverbanks and seasonal wetlands, which absorb excess water during the monsoon season.
