International audience; The dynamics of a sediment mixture is a typical issue for alpine rivers where poorly sorted sediments are found (Camenen et al., 2015). There exist some studies on the interaction between the two classes of a bimodal mixture (Wilcock et al., 2001, among others) but there are generally based on an initial well-mixed mixture. In nature, one often observes layers of sediments with different grain size distribution. In this study, we specifically focus on the dynamics of fine sand propagating over a bed made of coarse sand. One originality of this work is that we used high resolution imaging techniques to better describe the mechanisms at the fluid-sediment interface. |
