A nearly level alluvial plain that borders a channel and is occasionally inundated by floods (unless artificially protected). The landform is formed by sediment transport and deposition from flows over the streambank and lateral movement of the stream.\n\n3. A strip of relatively level land bordering a stream or river subject to flooding. Floodplain build up over time by deposits of sediment carried in flood waters.\n\n4. The flat or nearly flat land on the floor of a steam valley or tidal area that is covered by water during floods.\n\n5. The flat or nearly flat land along a river or stream or in a tidal area that is covered by water during a flood.\n\n6. A strip of relatively flat and normally dry land alongside a stream, river, or lake that is covered by water during a flood.\n\n7. The lowland and relatively flat areas adjoining inland and coastal waters, including flood-prone areas of offshore islands, that are inundated by the 100-year flood.",
