This occurs on the outside of the bend and forms a river cliff . An erosional floodplain is created as a stream cuts deeper into its channel and laterally into its banks. Cells that contain two sets of chromosomes are said to be diploid .

In essence this is what a floodplain is. This leads to the formation of a floodplain. This process reinforces the riffle-pool structure of a stream. 116 Many of the large and disastrous floods in deltas and estuaries are the result of a combination of coastal floods for example caused by storm surges and floods from rivers and rainfall says Philip Ward at Vrije University Amsterdam in The Netherlands.
