Abstract
Evidence is drawn from the literature of unidirectional flow to show that grain shape affects transport behaviour down to grain size 100µm and, in particular, that beds of grains of low sphericity adapt to flow in such a way that grain activity is diminished. Some evidence is offered that the adaptive process takes many minutes. Such ‘armouring’ is therefore relevant to tidal currents but not to currents generated by short waves.
