Gazipur 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.
Part of the greater Dhaka metropolitan area, the city’s rapid industrial growth has increased runoff into the Turag and Balu rivers during heavy monsoon rain. 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.
