A multilayer shallow water system for polydisperse sedimentation

Abstract:

This work considers the flow of a fluid containing one disperse substance consisting of small particles that belong to different species differing size and density. The flow is modelled by combining a multilayer shallow water approach with a polydisperse sedimentation process. The resulting model is less expensive, from a computational point of view, than a full coupled two- or three-dimensional sedimentation-flow coupled model. The new model is adequate in situations where the settling takes place from a suspension that undergoes horizontal movement such as the transport and deposition of suspended particulate matter in rivers and estuaries. Numerical examples are presented.
