Guwahati sits on the banks of the Brahmaputra River in Assam, one of the wettest and most flood-prone regions of India, where the June-to-September monsoon delivers extremely heavy rainfall across the wider river basin. The Brahmaputra’s seasonal rise regularly affects low-lying parts of the city and surrounding districts, and because the river responds to rainfall across a vast catchment stretching into neighboring states and countries, radar coverage of the broader region is essential for anticipating flood risk here.
