bed, movable — A stream bed made up of materials readily transportable by 

 the stream flow. 



bed, stream — The bottom of a stream below the low summer flow. 



braided river — A river containing two or more interconnecting channels 



separated by unvegetated gravel bars, sparsely vegetated islands, and, 

 occasionally, heavily vegetated islands. Its floodplain is typically 

 wide and sparsely vegetated, and contains numerous high-water channels. 

 The lateral stability of these systems is quite low within the boun- 

 daries of the active floodplain. 



carrying capacity, biological — The maximum average number of a given organ- 

 ism that can be maintained indefinitely, by the habitat, under a given 

 regime (in this case, flow). 



carrying capacity, discharge — The maximum rate of flow that a channel is 

 capable of passing. 



channel — A natural or artificial waterway of perceptible extent which 



periodically or continuously contains moving water. It has a definite 

 bed and banks which serve to confine the water. 



configuration — The pattern of a river channel (s) as it would appear by 

 looking vertically down at the water. 



contour — A line of equal elevation above a specified datum. 



cover, bank — Areas associated with or adjacent to a stream or river that 

 provide resting shelter and protection from predators - e.g., undercut 

 banks, overhanging vegetation, accumulated debris, and others. 



cover, fish — A more specific type of instream cover, e.g., pools, 

 boulders, water depths, surface turbulence, and others.
