Rapidly-migrating and internally-generated knickpoints can control submarine channel evolution [PDF]

Nature Communications, 2020
The authors analyse 9 years of time-lapse surveys in Bute Inlet, British Columbia (CA), to show how an active submarine channel evolves. They show how channel evolution is controlled by fast upstream-migration of steep knickpoints, which are similar to ...

Shallow mud detection algorithm for submarine channels based on improved YOLOv5s [PDF]

Heliyon
Submarine mud poses a risk to channel navigation safety. Traditional detection methods lack efficiency and accuracy. As a result, this paper proposed an enhanced shallow submarine mud detection algorithm, leveraging an improved YOLOv5s model to increase ...

Creep characteristics of muddy submarine channel slope instability

Frontiers in Marine Science, 2022
Creep is an important factor of muddy submarine channel slope instability. In this study, a sub-bottom profiler was used to monitor the continuous internal change of a muddy submarine channel slope in the laboratory to better understand the creep ...

Comparing Aggradation, Superelevation, and Avulsion Frequency of Submarine and Fluvial Channels

Frontiers in Earth Science, 2020
Constraining the avulsion dynamics of rivers and submarine channels is essential for predicting the distribution of sediment, organic matter, and pollutants in alluvial, deltaic, and submarine settings.

Channel incision into a submarine landslide on a Carboniferous basin margin, San Juan, Argentina: Evidence for the role of knickpoints

The Depositional Record, 2022
Emplacement of submarine landslides, or mass‐transport deposits, can radically reshape the physiography of continental margins, and strongly influence subsequent sedimentary processes and dispersal patterns.
