Both braided and meandering channel deposits are more coarse than the materials laid down by flooding. A number of other geomorphic features can be found on the floodplain. Intersecting the levees are narrow gaps called crevasses . These features allow for the movement of water to the floodplain and back during floods. Topographical depressions are found scattered about the floodplain.
Depressions contain the some of the finest deposits on the floodplain because of their elevation.
Oxbow lakes are the abandoned channels created when meanders are cut off from the rest of the channel because of lateral stream erosion . A delta is body of sediment that contains numerous horizontal and vertical layers. Deltas are created when the sediment load carried by a stream is deposited because of a sudden reduction in stream velocity. The surface of most deltas is marked by small shifting channels that carry water and sediments away from the main river channel. These small channels also act to distribute the stream's sediment load over the surface of the delta.
