Floodplains form when the water in a river or stream becomes too high and too thick to flow through easily. When two plates collide, the pressure of the collision can cause an earthquake. Meanders are produced when water in the stream channel erodes the sediments of an outer bend of a streambank and deposits this and other sediment on subsequent inner bends downstream.

An earthquake is a natural event that can happen anywhere on the Earth. Hence plains are thickly populated. The force of the water erodes and undercuts the river bank on the outside of the bend where water flow has most energy due to decreased friction. A corkscrew-like flow of water called Helicoidal Flow moves material from the outside of one meander bend and deposits it on the inside of the next bend. This deposition leaves a layer of sediment across the whole floodplain. The sediments are heavier and can hold more water, which makes the levees more stable. These areas are known as transitional waters. Bbc bitesize english critical essay. Why are the plains formed by river having dense population?
