Sand mining grinds down river systems and sparks floods
Unsustainable sand mining transforms the structure of rivers. By removing more than the river can naturally replace with the sediment it carries downstream, sand mining carves a deeper, narrower bed. This lowers the water level, speeds up flow and erodes banks – reducing the watershed's capacity to absorb excess water during floods.
