5 years monitoring this wonderful #beaver release site in #Yorkshire! Pulling together a wide range of evidence, we saw changes in hydrology (reduced peaks/baseflow increase), reduction in turbidity, and increased vertebrate species richness and aquatic plant diversity 🦫👍https://tinyurl.com/bdd9k2ke

Land Cover Change Drives River Flow Modifications in Central Chile
This study examines the combined effects of land cover change and ENSO on streamflow dynamics in four coastal catchments of central Chile, using a 45-year (1979–2023) dataset of remote sensing and hy...

Lecturing tip #312. Increase student attention and engagement in the field by having a herd of cows stare at them throughout. Some adaptations needed to the Roger Stevens building perhaps…

Applications open for a 3-year Post Doc position in Leeds (UK) on the #UKRI funded Still Waters project. We are looking for #hydrology #geomorphology modelling skills to embed surface hydrology into #malaria models with fieldwork in Zambia. Pls contact me for more details: tinyurl.com/3356rt44

Hi all! Just a reminder that the @bsg-geomorph.bsky.social BSG Annual Conference abstract deadline is tomorrow. The conference, celebrating 50 years of #ESP&L, is 16-18 Sept right in the very centre of Leeds… 1 minute from the railway station… and a conference dinner hosted in Leeds Armouries.

If your name’s not down… you’re not coming in. It’s great having #bees in our garden. Two ‘bouncers’ here guarding their entrance and bee-handling this unfortunate bee right across the garden. Perhaps ‘guard bees’ and ‘robber bees’ in action?

Well done @connieharpur.bsky.social on producing a wonderful poster at #EGU25. You smashed it and drew a crowd throughout your poster session. Maybe some new collaborations there too! Woop Woop!

On this years’ Portugal trip, while wandering over the student field sites we found some naked men. Thankfully, the Naked Man orchid (also generously known as the Italian man orchid). Good spot @kofitim.bsky.social - you have a good eye for these things! Nice hat too

Another gorgeous field day surveying the Yorkshire #beavers. Laser scans, UAV surveys, a bit of dGPS where trees allowed and some iPad LiDAR surveys too. That's the 7th annual survey complete. Loads of activity... and look! I think I stumbled on a beaver workshop?

Lovely to see a release of beavers into the wild in England… especially today on my annual beaver survey day of the #Yorkshire Beavers. Amazing changes here over 6 years… maybe next year the change will be that the fences have gone!

Lovely to be part of group meetings in Lusaka for the CIHR healthcare access project. We planned local/national dissemination, pulling together key messages across this wonderfully friendly, diverse and international team. Ranging from flood modelling to focus groups to tackle this complex challenge

Back in Zambia for a set of final project dissemination meetings in Lusaka. But a chance to stop by a #fluvial #geomorphology global highlight! The mighty Mosi oa Tunya/Victoria falls gearing up for what we hope is a good wet season this year 🤞🤞🇿🇲🇿🇲

What does 50 years’ worth of geomorphological knowledge look like? A full compilation of @bsg-geomorph.bsky.social the ESP&L print run saved from recycling… ahead of the annual BSG meeting here in Leeds celebrating exactly this milestone. On 16th-18th Sept: pop it in your diaries now!

2024 was also a record for the amount of water vapour in the atmosphere. Water vapour is a powerful greenhouse gas and a warmer atmosphere can hold more moisture, amplifying the CO₂ induced warming. The increased levels of water in the atmosphere mean that heavy rainfall events become more severe.

When we did this rather silly comparison picture highlighting glacier retreat in Norway over the last 140 years... I don't think any of us expected it to make it into a news story on the NRK website 😂. Such is life! I ❤️the scratchy image they have at the top: www.nrk.no/klima/brefor...

#Hydrology and #geomorphology can help us better understand environmental suitability for #malaria transmission. I’m excited to give this BSG seminar in two weeks with examples of our research from the last decade. That pic of me itself is at least a decade old 😂
Advert for the BSG seminar series on 2nd December. The talk is called Follow the Water: incorporating hydrology and geomorphology into estimate of malaria environmental suitability
