Description :
The aim of this paper is to use a series of laboratory flume experiments to quantify the differences in the organization of surface particles, at both grain and cluster scales, between armour layers created under conditions of sediment starvation (zero sediment feeding) and recirculation. The objective is to quantify and evaluate the relationships between bed surface topography and sediment availability. The implications of these observations in terms of sediment transport and bed roughness characterization are discussed.
