This <br />stream type consists of multi-threaded channels. As the power of the stream increases the <br />complexity of the braiding pattern increases. <br /> <br />Comment: Braided streams occur as the result of large or significant changes in slope, stream <br />flow, or sediment load. Multiple flow paths exist in braided streams and individual paths are <br />uncertain and often change in a response to major flows. There is continual spatial variation in <br />braided streams with bars and islands being formed and destroyed at a high frequency. During <br />major floods old channels can be suddenly reoccupied or new channels formed resulting in a <br />channel avulsion. At high stream power, a transition from a meandering, single-thread stream <br />(ST -4) to braided stream can occur. <br /> <br />Relative Stability: Low <br />Uncertainty: High, channel movement and channel avulsion <br />Sinuosity, P: 1.05 - 1.25 <br /> <br />7 <br />
