Journal Article
Published: 10 February 2025
Journal of Sedimentary Research (2025) 95 (1): 104–132.
... morphodynamics is not well understood due to the limited available monitoring data. Time-lapse bathymetric surveys were analyzed over a period of 20 years for two river-fed turbidite systems: eleven surveys for Bute Inlet (West Canada) and five for the Congo Fan (West Africa). Time-lapse maps show the evolution...
