Riverine wetlands depend on the flow of water conveyed by natural or artificial channels, including rivers, streams, ditches, and canals. They can form on floodplains, river terraces, and along channel beds, especially where the flows are seasonal or episodic. Very broad floodplains can contain wetlands that resemble depressional wetlands because they are confined to topographic depressions or hollows, but are classified as riverine because they depend on riverine flooding.
