1.1 Gravel- and cobble-bed streams: distinctions from other streams
Gravel- and cobble beds usually contain some sand, typically less than 10% in mountainous areas, and maximally up to about 50%. In mountain areas, gravel- and cobble bed streams may also contain large boulders. Thus, the entire range of bed-material particle size can span five orders of magnitude (i.e., from fine sand of 0.06 mm
