Bangladesh, situated at the confluence of several of South Asia's major rivers, suffers from floods almost every day. Major portions of the country are part of the Ganges Delta, the largest flood plain in the world. Each year in Bangladesh about 26,000km2, (around 18%) of the country is flooded,so far killing over 5000 people and destroying 7 million homes. During severe floods, the affected area may exceed 55% of the FLOODS and the Meghna. This volume is 95% of the total annual inflow. By comparison only about 187,000 million m3, of streamflow is generated by rainfall inside the country during the same period. The floods have caused havoc in Bangladesh throughout history, especially during the years 1966, 1987, and 1988. The 2007 South Asian floods affected a large portion of Bangladesh.Over half the country is less than 1m above sea level.aa
Floods in Bangladesh can be divided into three categories: *[[Monsoon]] flood - seasonal, increases slowly and decreases slowly, inundates vast areas and causes huge losses to life and property; *Flash flood - water increases and decreases suddenly, generally happens in the valleys of the hilly areas; and
Tidal flood - short duration, height is generally 3m to 6m, blocks inland flood drainage.
