One year to go until Gravel Bed Rivers 10! We look forward to seeing you all in Scotland. Our confirmed speaker list is available here: www.gbr10.uk/programme
A photo of a river with the following text on top: Gravel Bed Rivers 10 From Grain to Globe ONE YEAR TO GO! The countdown begins - we are officially one year away from Gravel Bed Rivers 10 'From Grain to Globe' We look forward to welcoming you to Aviemore, the heart of the Scottish Highlands, between 7 - 11 September 2026. We are delighted to share our confirmed speaer list which can be found at https://www.gbr10.uk/programme.

What if you laid out all the meanders of a river along a straight line, so that you can break the river into straight-ish segments and fill arbitrary spaces? This is the Purus River in Brazil; you can see how it is getting wider and the meanders are getting larger in the downstream direction
The meandering planform of the Purus River (a tributary if the Amazon), shown as white wiggles on a black background. The width of the river and the size of the meanders are increasing downstream (top to bottom, left to right).

Global RIver Topology (GRIT) is a new and improved global river network that represents bifurcations, multi-thread channels and canals. Great to see this important output from the NERC-funded EVOFLOOD project. See more here: doi.org/10.1029/2024...

River datasets often miss forks and branches found in highly populated floodplains and deltas. As flooding grows more severe, accurate mapping of these areas is more important than ever.

New Global River Map Is the First to Include River Bifurcations and Canals - Eos
GRIT provides a much more detailed look at how rivers merge and split, which could enhance hydrological modeling, flood forecasting, and water management efforts.

Great to share the latest output from the UK-Philippines project (funded by NERC/DOST-PCIEERD), with inputs from @uofgges.bsky.social, @livunigeog.bsky.social and many others.

Local factors did not predict river mobility (e.g., active channel width, valley floor width, confinement ratio) and we found no relation between channel pattern type (e.g., braided vs. meandering) and patterns/rates of adjustment.

Rivers were characterised by zones of relative stability interspersed with zones of high mobility, but these patterns varied between systems and even between different reaches of the same river, highlighting the idiosyncratic nature of river mobility.

We analysed 32 years of Landsat satellite imagery for 10 major river systems in the Philippines, processing over 10,000 images through Google Earth Engine (GEE) to quantify patterns and rates of river mobility.

Big data show idiosyncratic patterns and rates of geomorphic river mobility - Nature Communications
In this study, satellite-derived locational probabilities are analysed to unravel records of river adjustment in the Philippines. The data show spatially non-uniform variability in along-valley patter...
