of damage from the flooding, and those that were open had too many patients, resulting in everyday injuries becoming fatal due to lack of treatment. 700,000 hectares of crops were destroyed, 400 factories were forced to close, and there was a 20% decrease in economic production. Communication within the country also became difficult. The 1999 floods, although not as serious as the 1998 floods, were still very dangerous and costly. The floods occurred between July and September, causing many deaths, and leaving many people homeless. The extensive damage had to be paid for with foreign assistance. The entire flood lasted approximately 65 days. The 2004 flood was very similar to the 1988 and 1998 floods with two thirds of the country under water. In early October 2005, dozens of villages were inundated when rain caused the rivers of northwestern Bangladesh to burst their banks.The floods that hit Bangladesh in 2007 affected 252 villages in 40 districts causing millions of people became homeless. Floods also occurred in 2015 and 2017. Details of the 2017 flood(s) in Bangladesh In 2017, unpredicted early heavy rain caused flooding in several parts of Bangladesh and damaged pre-harvested crops in April. The April flood continued until the last week of August and caused substantial damage to housing, property, and infrastructure. Using Sentinel-1, comprehensive flood inundation maps of Bangladesh for March, April, June, and August 2017 show that the presence of perennial waterbodies in March 2017 covering an area of 5.03% in Bangladesh. In April, a total flood-inundated area was 2.01%, most inundation occurring in cropland (1.51%), followed by rural settlement and homestead orchard areas (0.21%) and other areas (0.29%). Similarly, more area was inundated during the catastrophic June and August months, with inundation covering 4.53% and 7.01%, respectively. Climate variability From March to September in a typical year, the citizens of Bangladesh are the most susceptible to major flooding, as a mixture of the monsoon seasons and the rising of major rivers and their tributaries reach their peak as the snow starts to melt and the rain starts to pour. the rivers flow from India into Bangladesh also sometimes the Himalayas. Widespread flooding in Bangladesh, as seen in 1988, 1998 and 1991 has caused widespread destruction in one of the least developed countries in the world. With three of the world's mightiest river systems and being situated in the world's largest delta, riverbank erosion is taking
