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.

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 ...

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 🤷

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
