Abstract

This study examines the magnitude of bias associated with compensation events that occur at the temporal scale of braided channel evolution, and identifies specific channel kinetics that cause scour-fill compensation. By using a small-scale physical model it is possible to essentially eliminate compensation resulting from variation in discharge by maintaining constant discharge. Also, river-bed topography can be mapped relatively easily and frequently using a flume. Hence, a small-scale braided gravel-bed river model is used in this study to examine the magnitude and nature of scour-fill and to relate the spatial pattern of compensation to braided channel kinetics
