Abstract: A size-dependent particle and particle-associated contaminant transport and fate model is presented. The unsteady, two-dimensional model couples the water column and bed and enables analysis of size-dependent processes such as sedimentation, reaction (coagulation), erosion, and sorption. The particle-contaminant linkage is also size-dependent, provided by a surface area based partition coefficient. Expected results outline the conditions where coagulation becomes significant in particle flux.
