I hope you managed a cheeky round whilst you were there

An Evaluation of Low‐Cost Terrestrial Lidar Sensors for Assessing Hydrogeomorphic Change Fixed monitoring platforms using small form lidar sensors offer insight into hydrogeomorphic processes at user defined temporal resolution Change detection products are within 2–4 cm of those pro...

Nice contribution! - we used the livox for change detection in another environmental setting and found them to be similarly useful agupubs.onlinelibrary.wiley.com/doi/full/10....

Unsupervised image velocimetry for automated computation of river flow velocities Abstract. Accurate, long-term measurements of river flow are imperative for understanding and predicting a broad range of fluvial processes. Modern technological advances are enabling the development ...

I’m delighted to share that our latest research has just been published in HESS.

We developed an unsupervised workflow to estimate river surface velocities from videos. Testing on 11,000+ videos against 274 gauging measurements showed excellent agreement.

Incredible week with our Stage 1 Physical Geographers in the Lake District looking at physical processes and landforms @newcastleuni.bsky.social

Last week we took 31 students to the Netherlands to look at physical geography, coastal processes, and climate change and adaption in action. Great to hear these student reflections that underscore how important field experience is to our discipline! @hassfacultyncl.bsky.social

Getting Lisflood to compile with GPU-accelerated solvers has reduced model runtime by 5-10x. If only I knew what I did differently for it to compile successfully compared to the dozen failed attempts. Guess I’ll be keeping this VM instance forever 🤷

Worst photo ever of the site but it was raining like crazy during the installation

For this site we used a standard Hikvision camera connected to Raspberry Pi via Ethernet. It’s probably a bit out of date now but we produced a handbook to document the setup: www.dropbox.com/s/r3zx8xpvoc...

In this work we analysed over 11,000 videos and compared the outputs to several hundred flow gauging measurements made by the Environment Agency

Our latest paper on implementing image-based flow gauging techniques in an automated environment is now open for public discussion. We’d love to hear feedback from the hydrological community hess.copernicus.org/preprints/he...

It’s been great to spend a bit of time in the field recently. Here we are working with the National Trust to assess the effectiveness of a single intervention to enhance flows across a floodplain
