Delineative River Criteria for D4:
"Moderately steep glacial valleys, alluvial fans, narrow fluvial mountain valleys and
terraced valleys in coarse alluvium. Can occur in gravel splays, and coarse delta deposits.
Gravel bed with smaller quantities of cobble. Typical is a bi-modal distribution of sands.
Stream bank materials generally finer than bed, actively eroding."
