How Do Turbidity Currents Accelerate?
Flume experiments show that a self-reinforcing cycle can strengthen the currents responsible for transporting large amounts of sediment to the deep oceans.

In a Submarine Trough, Permeable Rocks May Lead to Quakes
In Japan’s submarine Nankai Trough, rock permeability is much higher when measured at larger scales, likely because of big fractures and faults that are not captured at small scales.

Landslides Send Carbon-Rich Soils into Long-Term Storage
Earthquake-triggered landslides move soils down steep slopes and deposit the sediments near rivers, sequestering the carbon contained within them for millions of years.

Insensitivity of Total Sediment Flux to Hydraulic Details
The total sediment mass transported by flow under different sets of regimes is insensitive to the exact details of hydraulic forcing, but what matters is cumulative transport capacity.

How Are Sediment Pulses Generated?
A new long-term flume experiment shows that bed load gravel travels downstream in recurring, 10-hour pulses even when water flow and sediment supply are constant.
