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!

WATERSHED Investigations @watershed-i.bsky.social · Apr 17

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?

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.
