It was great presenting some of my recent work to colleagues in @lborogeog.bsky.social on #flooding, #sediment and novel methods to monitor and model it... watch this space as papers coming soon 😁
lborogeog.bsky.social Geography and Environment at Loughborough University @lborogeog.bsky.social · 20d
Last week, we heard from Research Associate @joshwolstenholme.bsky.social on river sediment transport and flood risk that led to some great questions and further discussion! 🌊
GEOGRAPHY SEMINAR SERIES Join us Wednesday 29th October 1:00 PM in EHB205 Dr Josh Wolstenholme Loughborough University Sediment transport and flood risk: Why is it important and how can we monitor it? One in four people globally are at risk of extreme flooding, a number expected to rise under a changing climate. Yet current flood risk assessments often omit key river processes, notably sediment transport, due to high uncertainty, limited field data, and computational cost. In this talk, I will first present a series of numerical experiments in the upland catchment of Glenridding Beck (Cumbria) that demonstrate how sediment dynamics amplified the impacts of Storm Desmond in 2016. I will explore how increasing storm duration and intensity can trigger thresholds where sediment transport significantly enhances flood risk. Second, I will discuss new work on using smartphone LiDAR to capture small-scale river morphology, showing that it can produce results comparable to traditional survey methods while enabling low-cost, repeatable monitoring for model calibration and validation.

🚨 New paper out now in @egu-esurf.bsky.social! 🚨

We explore the geomorphic response of two river reaches to leaky dams, focusing on bathymetric change, planform evolution, water levels, and grain size distribution—helping to address the gap in field studies

Over the moon to finally announce our NERC: Natural Environment Research Council funded project Charnwood Champions 🥳

This project has been a dream of mine for many years after witnessing the inconsistancy and inequality of opportunities for children to access the natural environment

🌱 What if environmental science belonged to everyone?

We’re proud to launch Charnwood Champions: A Passport to Inclusive Environmental Science – a bold, place-based project reimagining environmental learning, opportunity, and leadership.

When I was 5 (on Rt), my family moved to Kenya. I felt safe & happy in this vibrant place, but I soon became aware of the privilege I held. My early experiences shaped my understanding of inequality & inspired me to strive for a world where every child can thrive, just as I did 🌍💚 #WorldChildrensDay
This photo shows a group of five people standing outdoors on a sunny day. The group includes an adult man on the far left wearing a light-colored shirt, a young woman and adult woman in the middle—one wearing a white top and the other wearing a blue sleeveless top—and two young children. The children, one with short blonde hair and the other with long blonde hair (me), are positioned at the front and right, respectively. The group appears to be smiling and enjoying the moment, with a thatched-roof structure and trees in the background. The lighting is bright and natural.
