Anastomosing Rivers
Anastomosing rivers are sinuous, low-gradient channels consisting of multi-
ple interconnected branches transporting a suspended or mixed load (Fig. 22)
(Schumann 1989). In plan view the splitting and rejoining of anastomosing
channel branches may at first appear similar to braiding, but many distinct differ-
ences exist (Fig. 16 and 22). Whereas flow is fairly evenly divided amidst differ-
ent braided flow paths, one main channel is characteristic of anastomosing
channels, with only overbank flow feeding smaller anabranches. Given the high
suspended load content and fine-grained bank material, channel width:depth
ratios are lower and sinuosities higher than for braided rivers. Also, channel
position is more stable along anastomosing rivers. Anastomosing channels can
