Sediment resuspension and transport by internal solitary waves

L Boegman, M Stastna - Annual review of fluid mechanics, 2019 - annualreviews.org
Large-amplitude internal waves induce currents and turbulence in the bottom boundary
layer (BBL) and are thus a key driver of sediment movement on the continental margins …

Observations of enhanced sediment transport by nonlinear internal waves

A Zulberti, NL Jones, GN Ivey - Geophysical Research Letters, 2020 - Wiley Online Library
