Quantifying Bed Surface Roughness in Bedrock and Boulder‐Bed Rivers Using high-resolution river bed topography, surface roughness metrics are quantified across various spatial scales A comprehensive description river bed topographic variability requires the concu...

📣 New paper: Quantifying river bed roughness.

💧Multiple metrics are required to fully describe river bed roughness.
💧River beds with differing features can be distinguished using roughness data.
💧Potential implications on flow resistance and sediment transport.

EGU tomorrow (Wednesday) - come chat about river roughness and flow resistance, 1045-1230 Hall X3 - posters X3.102 and X3.95! @rebeccahodge100.bsky.social @dwhit.bsky.social

Attending #EGU25? Interested in the role of #iPad #LiDAR and how well it performs in river systems for collecting #3D data? Checkout some of mine and @houseago.bsky.social's work in GM2.2 - Monday 16:15-18:00 [Hall X2, X2.92]!

Excited about what’s to come following this workshop in Durham!

Further research on including LWD is incoming! Let me know if you have any thoughts, field-sites, or want to chat in general!

Five colour photos of rough-bed rivers. These are rivers whose bed is made from coarse sediment and/or bedrock.

🚨Interested in flow resistance in rough-bed rivers? Our new paper reviews different approaches from within and beyond geomorphology for calculating flow resistance from channel topography: onlinelibrary.wiley.com/doi/10.1002/... With @richhardy.bsky.social and others.
