In this report the classical concept that mean bed elevation over an entire stream reach is lowered by scour during flood-wave passage and is restored by deposition in the waning flood phase mean-bed scour and fill is challenged. The alternative that both scour and fill occur concurrently at different migrating loci within a reach local scour and fill is more consistent with published field data. The field and laboratory investigations reported suggest that mean-bed scour and fill in a uniform channel is minor compared to local scour and fill caused by bedform migration, and that maximum local scour and fill may occur on the waning flood in some instances.
