Sediment Transport in Viscous Fluids

Andrea Bertozzi
University of California, Los Angeles (UCLA)

We consider the problem of particle laden thin film flow in viscous liquids. This problem is important for understanding slurry flows in a variety of industrial and environmental contexts including the food industry, coal industry, and geological events such as mudslides.
Only recently has a mathematical theory been developed for this problem, where the sediment is heavier than the liquid. We talk about the challenges involved in modeling sediment transport and settling and the ensuing mathematical problems that arise from these problems.
