Abstract: This note comments on the observation that the decrease in the rate of scour of freshly deposited muds is attributed to a gradual development of a resistive bed roughness pattern. Since prolonged fluid stressing causes internal rearrangement of bed particles that results in pronounced defects in the bed surface, there is a brief period of increased scour in the early stages of bed consolidation. Experimental studies show this roughness pattern gradually reaches a certain limiting size beyond which the scour rate decreases and bed stability is enhanced.
