A challenge for students on the @ncl-geography.bsky.social Netherlands fieldtrip today with ~1m storm surge completely inundating de Slufter field site - great resilience reconsidering what was possible, and retargeting some of their project work. Fantastic to show this dynamic environment in flood!
Biological Invasions
This study from 'Biological Invasions' shows invasive non-native plants indirectly destabilise riverbanks by suppressing native vegetation, increasing bare ground, and reducing winter shear strength by around 30%. bit.ly/4qJilB3 @zarahpattison.bsky.social @drchrishackney.bsky.social #bioinvasions

My third PhD chapter has just been published, we assessed the impact of Himalayan balsam invasion on riverbank stability. A massive thanks to @zarahpattison.bsky.social @drchrishackney.bsky.social @dralanlaw.bsky.social

View of the Tonle Sap River in Cambodia with several boats, including a floating restaurant, amidst a calm water setting.
A study co-led by our experts highlights how sand mining is endangering the normal functioning of the Tonle Sap Lake, the largest freshwater lake in Southeast Asia, potentially affecting 23 million people.

Important work here from @drchrishackney.bsky.social and colleagues -
The Junior Deputy Chair (JDC) assists the Chair and Senior Deputy Chair with the day to day running of the society. The JDC is an elected one-year role, with the incumbent assuming the role of Senior Deputy Chair in the subsequent year, and then the role of Chair in the year after.
Outreach Vice Chair is responsible for coordinating the Outreach Committee’s activities, including promoting geomorphology to the public and encouraging the teaching of geomorphology at schools, colleges, universities, and to the wider public. The position is held for a three-year term.
⏰ We are still looking to fill the positions of Junior Deputy Chair and Outreach Vice Chair on our Executive Committee starting in September. Please get in touch if you are interested in applying! Brief descriptions for the roles can be found below ⬇️

This means they provide more friction and resistance to the flows of water in the river, and change the dynamics of suspended sediment flowing over them.
In this new work we quantify the geometry of a range of natural dunes and bedforms impacted by sediment extraction along the Mekong River in Cambodia. Anthropogenic bedforms are larger and steeper than natural sand dunes.
🚨New paper alert 🚨 Ever wondered how sand extraction may be altering the bed of sandy rivers? How these changes influence flow and sediment transport? Well wonder no more!

Booming factory growth in Vietnam is requiring more sand to be imported from its neighbours www.bloomberg.com/graphics/202...
Men mining sand by hand. This back breaking work, often undertaken by the world's poorest people, supplies the right consistency of sand needed to make concrete. Desert sand, for instance, is too smooth to be useful for building. Sand can be pounded into the right shape but that's an expensive process. So, instead, river beds, sea beds, estuaries, lake beds, are being dug for sand - harming wildlife, creating deeper water bodies more susceptible to algal blooms, & causing the erosion of banks, with the loss of people's homes & some of the world's finest farmland. This erosion encourages salt water ingress - making well water undrinkable.
As the world constructs ever more buildings, we're destabilising rivers, lakes, deltas & loughs to gather the sand we need for all that concrete. What harm are we causing? How can we reduce that harm? Can we use alternative materials in concrete or reduce the amount of concrete we use?

Next week we are hosting two talks to celebrate International Geomorphology week. Dr Lynda Yorke will discuss inclusive fieldwork in the geosciences on Wednesday. On Friday, Gwyn Nelson from the Wales Coastal Monitoring Centre will present a national approach to communicating coastal change.
