Abstract

Channel instability has occurred in the Bell River in the form of meander cutoffs, a number of which have occurred since 1952. This study reports the results of an investigation into the effect of vegetation on channel form and stability over a 17 km stretch of channel. Riparian vegetation increases bank stability and reduces channel cross-sectional area, thereby inducing stability at flows less than bankfull. The reduced channel capacity is thought to result in more frequent overbank flooding which may ultimately lead to channel avulsion
