Geography of Bangladesh

Most of the areas of Bangladesh lies within the broad delta formed by the Ganges and Brahmaputra rivers. Lands are exceedingly flat, low-lying, and subject to annual flooding. Much fertile, alluvial soil is deposited by the floodwaters. The only significant area of hilly terrain, constituting less than one-tenth of the nation's territory, is the Chittagong Hill Tracts in the narrow southeastern panhandle of the country.
