I’ve stopped making a to-do list. But - have started keeping a β€˜have done’ list that I complete at the end of every day. Typically a far more positive exercise…

This looks super interesting. Esp for folk at the intersection of science/humanities and water.

A satellite image of the southern North Sea, showing land in white and the sea in shades of grey. A semicircular pattern between UK and France can be seen in the English Channel. White dots in the sea are windmills and ships.

A wave train entering into the North Sea, seen by #Sentinel1 on 12 August. I am guessing it's tidal-related, but I have never seen this kind of signal in this region in SAR data before, pretty cool 😎

πŸ‘€ There have been some exciting arrivals since I joined MMU Dept Natural Sciences: flume for the BiG Lab, LaVision PIV, Dr Lizzie Dingle and her very cool experiments, some feisty crayfish 🦞, & now, Prof. @tomcoulthard.bsky.social πŸ₯³. Chuffed to bits that Tom is now a colleague. Exciting times ahead!

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 story. Hg production fell to zero in 2020 but now rising (illegally it seems) to propel gold extraction in the Amazon financed and facilitated by Mexicos drug cartels… Horribly toxic - I thought mercury use had been nearly eliminated.

Demand management now prevents any endless recycling of crap proposals - and NERC won’t allow any props to be fed into AI - which is why they switch off auto translate on meeting recording…

Here's a fun anomaly for an inland flood risk map. It's genuinely very helpful in places: check-long-term-flood-risk.service.gov.uk/map But it's based on scans of the ground, & the processing gets confused sometimes. I think the 4-storey pitched roof of this hospital is probably safe from flooding!

I’m fairly sure the report remit was for E&W - as env regulation is fairly heavily devolved? There’s certainly a large section on Wales 🏴󠁧󠁒󠁷󠁬󠁳󠁿 at the beginning…

Interesting revert to 8 regions for water management. Which is imho probably sensible - but was this what the NRA did prior to privatisation? Though NRA (National Rivers Authority) was more wq and flood focussed. Clearly Wq had come up the agenda. #flooding #cunliffe

So the Cunliffe report is out today. Couple of first takes: 1. It seems comprehensive - lots of concise detail but 2. Nothing about flooding (that I can see) which in most urban areas is intrinsically linked to sewage systems and water utilities. assets.publishing.service.gov.uk/media/687d5c...

I see NERC is reverting to a policy from 15(??) or more years ago on resubmissions. I suspect it will be counter productive to NERC workload - as checking for this will not be easy, and building on this - it looks quite easy to game/work around. So - I’m left with why bother (with the new policy!)
