Components of a Stream Corridor <br />A stream corridor includes the stream itself (the water in the stream and the <br />channel) plus the riparian area along the stream, the floodplain (the land that <br />floods at least occasionally), and groundwater lying underneath all of these <br />features. The components of a stream corridor are: <br />• Stream channels <br />• Riparian vegetation <br />• Active floodplain <br />• Groundwater <br />• Surface water quality <br />The figure below depicts an idealized stream corridor along a larger stream. <br />Biological and Physical Components of a Complex Stream Corridor <br />.
