Generally:
Channel widened over entire reach length. Undercut banks are absent. Pools are infrequent (<15% of channel length) and shallow (< one-third metre deep). Riffles are extensive (>80% of channel). Elevated mid-channel bars (bar tops higher than bank tops) are present and have steep and easily disturbed downstream faces. LWD is clumped into jams. |
