The 28 November 2020 Landslide, Tsunami, and Outburst Flood - A Hazard Cascade Associated With Rapid Deglaciation at Elliot Creek, British Columbia, Canada

M. Geertsema et al.

Summary: This article describes and models the recent landslide, tsunami, outburst flood, and sediment plume in the southern Coast Mountains of British Columbia, Canada. The use of physically based models allows for real-time simulations, improving understanding of similar hazard cascades and the associated risks.

Watershed Classification Predicts Streamflow Regime and Organic Carbon Dynamics in the Northeast Pacific Coastal Temperate Rainforest

Ian J. W. Giesbrecht et al.

Summary: In this study, a hydro-biogeochemical classification system was developed for watersheds draining to the coastal margin of the Northeast Pacific coastal temperate rainforest. Cluster analysis was used to group watersheds into 12 types based on watershed properties, and the classification was validated using streamflow and dissolved organic carbon measurements from rivers. The results showed that watershed types corresponded with differences in streamflow regime, mean annual runoff, DOC seasonality, and mean DOC concentration.

Fill, flush or shuffle: How is sediment carried through submarine channels to build lobes?

Maarten S. Heijnen et al.

Summary: Submarine channels serve as the primary conduits for land-derived material to enter the deep-sea. This study investigates the magnitude-frequency-distance relationships of turbidity currents and sediment transport patterns within a submarine channel-lobe system using repeat seafloor surveys and turbidity current monitoring. The results provide new insights into mass redistribution and particle residence times, as well as the processes of sediment shuffling and burial. The findings also emphasize the potential hazards to seafloor infrastructure and highlight the importance of understanding sediment dynamics in submarine environments.

First source-to-sink monitoring shows dense head controls sediment flux and runout in turbidity currents

Ed L. Pope et al.

Summary: Turbidity currents, one of the most important sediment transport phenomena on Earth, have been poorly understood due to limited direct measurements. This study analyzes the largest number of turbidity currents monitored to date, revealing their structure and evolution. The study finds that turbidity currents can be classified into two types: fast and dense or slow and dilute, with a transitional flow head in between. Dense heads of turbidity currents have a significant impact on sediment transport and can extend into the deep sea.

Knickpoints and crescentic bedform interactions in submarine channels

Ye Chen et al.

Summary: This study investigates the distribution, variation, and interaction of knickpoints and crescentic bedforms in Bute Inlet, British Columbia, revealing that knickpoint migration is driven by frequent turbidity currents, affecting seafloor reorganization and the morphology of bedforms. The interactions between flows, knickpoints, and bedforms are important as they likely dominate the character of preserved submarine channel-bed deposits.
