dredges. Trench fill, stone fill, and timber-pile revetments were installed to
straighten and prevent channel migration. Trench fill was used to move the river
inland, and stone fill or timber-pile were used to shift the banks riverward (Combs
et al. 1994 ).
In order to develop and maintain channel depth against a revetment at the
opposite bank, stone dikes were placed on the convex bank. By constricting the
channel, scour is induced, which preserves the depth and reduces unwanted
deposition. Where channel depth is crucial, kicker dikes push the channel crossing
to the opposite bank. These dikes are an extension of the upper reach revetment
and are used to preserve navigability, while helping to reduce maintenance
dredging. After the completion of the channel realignment, 29 bendways were
