Rangpur sits in Bangladesh’s Ganges-Brahmaputra delta, one of the most flood-prone regions on Earth, where the summer monsoon from June through October combines with the rivers’ own seasonal rise to produce widespread flooding most years.
In northern Bangladesh near the Teesta River, the city monitors a river whose upstream flow from India’s Sikkim and West Bengal states shapes much of its flood risk. Because the Ganges, Brahmaputra, and Meghna rivers all drain vast catchments across the Himalayas and northern India before reaching Bangladesh, a wet monsoon far upstream can raise water levels here even without heavy local rain, and Bangladesh’s Flood Forecasting and Warning Centre uses radar alongside river gauges to track both direct rainfall and the rivers’ slower, larger rises.
