The topography of Sivasagar is overwhelmingly characterized by the flat, low-lying alluvial plains typical of the Brahmaputra basin. The city sits at a relatively low elevation of approximately 95 meters (311 feet) above sea level.
While the city proper is flat, the wider district features gentle undulations that provide the perfect drainage required for tea cultivation. There are no major mountains or canyons within the city limits, but the distant foothills of the Patkai range and the Naga Hills can be seen on clear days to the south and east. The flat plains are occasionally interrupted by massive historical human-made tanks (reservoirs) like the Joysagar, Gaurisagar, and Sivasagar tanks.
