What is a floodplain?
–A floodplain (or floodplain) is a generally flat area of land next to a river or stream. It stretches from the banks of the river to the outer edges of the valley. A floodplain consists of two parts. The first is the main channel of the river itself, called the floodway. Floodways can sometimes be seasonal, meaning the channel is dry for part of the year. #GKbyMilitaryChoice

–The flood fringe extends from the outer banks of the floodway to the bluff lines of a river valley.

Bluff lines, also called valley walls, mark the area where the valley floor begins to rise into bluffs.

–There are two major processes involved in the natural development of floodplains: erosion and aggradation. The erosion of a floodplain describes the process in which earth is worn away by the movement of a floodway.

Aggradation (or alluviation) of a floodplain describes the process in which earthen material increases as the floodway deposits sediment. A river erodes a floodplain as it meanders, or curves from side to side.
