Riverbank Erosion is an endemic natural hazard in our country. When rivers enter the mature, they become sluggish and meander or braid. These oscillations cause extreme riverbank erosion. It is a perennial problem in our country. • It has been estimated that tens of thousands of people are displaced annually by river erosion in Bangladesh, possibly up to 100,000. Many households are forced to move away from their homesteads due to riverbank erosion and flood. • As per different sources, 500 kilometres of riverbank face severe problems related to erosion. The northwest part of the country is particularly prone to riverbank erosion, which has turned the region into an economically depressed area.
