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.

More women in Malawi turn to sand mining after drought, floods hit incomes but the practice makes land less resilient to disaster

Interested in the role of sediment transport processes on increasing #flooding? Our new preprint that systematically explores the role of #rainfall on amplifying flood hazard is out! doi.org/10.21203/rs.... @floodskinner.games @drchrishackney.bsky.social Matt Perks & @bedforms.bsky.social

Flood hazard amplification by intra-event sediment transport

Rivers are dynamic, with channel size and shape adapting to fluctuations in water and sediment supplied from their upstream catchments. These changes directly affect flood conveyance capacity, yet sed...
