Bangladesh, a nation of rivers, is in essence a large delta comprised of three significant rivers; the Ganges, Brahmaputra and Meghna.
Subsequently, Bangladesh is also one of the most flood-prone countries in the world. When the spring snows melt in the Himalayan Mountains the rivers often overflow running south to the sea.
Replete with mangrove forests and tropical rain forests, the overall land is mostly flat, with a few hilly areas in the east and southeast.
The highest point, Keokradong, peaks at 4,035 ft. (1,230 m), while the lowest point of the country is the Indian Ocean (0 m).
