Sand mining far outpaces natural supply in a large alluvial
2021-9-30 The greatest annual volume of sand transported by the river in the period of observation was in 2018, when it reached an estimated 10.9 Mt (0.8 to 30 Mt). Comparing an extraction volume of 50 Mt (35 to 65 Mt) for 2018 to the natural supply, nearly 5 (2 to 43) times the volume of sand supply is being removed.
