New paper from @dwhit.bsky.social's PhD work now available #OA in River Research and Applications: Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales onlinelibrary.wiley.com/doi/10.1002/...

📣 New Paper! Pebble shape, size and arrangement control their resistance to transport… we did the stats to simplify how bed texture influences grain mobility! With @edwinbaynes.bsky.social, @sterice.bsky.social and Kate Mathers ⬇️⬇️ agupubs.onlinelibrary.wiley.com/doi/10.1029/...

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...

🚨 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 With @edwinbaynes.bsky.social, @rebeccahodge100.bsky.social, @sterice.bsky.social & Elowyn Yager ⬇️⬇️

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 ...

#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.
