• Description:
  Channel instability is manifested as lateral bank erosion, progressive degradation of the streambed, or natural scour and fill of the streambed. Lateral stability is related to stream type, and four major stream types having different stability characteristics are distinguished: equiwidth, wide-bend point bar, braided point-bar and braided. Measurements of bank erosion on a study group of 36 streams indicate that equiwidth streams have the lowest lateral erosion rates and braided point-bar streams the highest. Also, erosion rates Increase with stream size. Significant degradation of the streambed can usually be detected from indirect field evidence. The sites of greatest potential scour along a channel can be identified from channel configuration.
