The People’s Republic of Bangladesh, formerly East Pakistan, is bordered to the west and northwest by West Bengal (India), to the north by Assam and Meghalaya (India), to the east by Assam and Tripura (India) and by Myanmar (Burma) to the southeast. The landscape is mainly flat. A large part of Bangladesh is made up of alluvial plain, caused by the effects of the two great river systems of the Ganges (Padma) and the Brahmaputra (Jamuna) and their innumerable tributaries. In the northeast and east of the country, the landscape rises to form forested hills. To the southeast, along the Burmese and Indian borders, the land is hilly and wooded. About one-seventh of the country’s area is under water and flooding occurs regularly.
