कारण और संदर्भ

Bangladesh's rivers form a dense, shifting drainage network that transports water and sediment through a low-lying delta. The governing relationship is: Seasonal discharge, sediment load, channel migration, avulsion and erosion-deposition continually reshape bars, chars, banks and floodplains.
