Sediment Wave Formation Caused by Erosional and Depositional Turbidity Currents: A Numerical Investigation

摘要

Results are presented from two-dimensional direct numerical simulations of sediment wave formation via a succession of erosional and depositional turbidity currents. For currents propagating down a slope, we observe the formation of upstream migrating periodic sediment waves. The strength of the wave formation process is discussed as function of the governing dimensionless parameters.
