Abstract

In the present work, a two-layer model is introduced to study the dynamics of transitional flows. It considers a dense basal layer with high density that is characterized by a non-Newtonian rheology, and a dilute upper layer of variable density constituting a turbulent turbidity current with Newtonian rheology. Results from this depth-averaged two-layer model are presented for a 2D case on idealized bathymetry featuring a slope break, as well as for a hypothetical 2D case study on an actual submarine bathymetry.
