Bangladesh is the country that experiences the most flooding. Its low-lying area, combined with over 230 rivers, also makes it the country most susceptible to soil erosion and saltwater intrusion.
About 18 percent of the country is flooded every year. Combined with a population density of over 2,600 people per square mile, the flooding is responsible for over 5,000 fatalities annually. During times of severe flooding, up to 75 percent of the country may be affected. This is because over 60 percent of the country is only 5 meters above sea level, with 80 percent located in the flood plain.
