Influence of Grain Arrangement on Particle Mobility and Patterns of Variability Between Gravel Bed Rivers Gravel bed surface-structure and mobility forces are quantified at 45 different rivers in England and Wales Surface texture is controlled by grain shape and size; this complicates bed stability c...

📣 New Paper!

Pebble shape, size and arrangement control their resistance to transport… we did the stats to simplify how bed texture influences grain mobility!

The Influence of Gravel‐Bed Structure on Grain Mobility Thresholds: Comparison of Force‐Balance Approaches Two different novel force-balance models are used to estimate grain mobility thresholds using resistance force and microtopography data An automated point cloud segmentation approach is compared ...

🚨 The first publication from my PhD thesis is out now in @jgrearthsurface.bsky.social!

We use force-balance models to estimate grain mobility thresholds for 45 riverbeds across England and Wales

A view down a laboratory flume. There are battons attached to the wall, sparse cobbles on the bed, and water flowing down the middle.

#FlumeFriday Our rough-bed river experiments now have rough walls as well! Great to see what @dwhit.bsky.social and @houseago.bsky.social have been up to.
