Summary	We will develop a physics-based, turbulence-resolving model for cohesive and non-cohesive mixtures that couples continuum (clay-silt) and discrete (sand) phases to simulate sediment transport and small-scale (< 1 m) bed-form dynamics. We hypothesize that the partial transport rates of the cohesive and non-cohesive sediment constituents are a power-law function of their respective volumetric fraction. Our long-term objective is to develop a complete suite of microscale simulation tools for sediment transport to improve our ability to predict sedimentary sorting processes and bathymetric evolution at operational length and time scales.
