Generally:
Step-pool morphology continues to exist because boulders are not moved by stream flow. Large gaps exist adjacent to many large boulders so stream flow moves around stones. Finer-textured sediment removed from upstream of boulders. Channel consists of series of large boulders separated by bedrock chutes. Banks consist primarily of non-alluvial materials and are not eroded (pools are not evident along channel banks). |
