Sand-and-gravel mining in stream channels can damage public and private property. Channel incision caused by gravel mining can undermine bridge piers and expose buried pipelines and other infrastructure. Several studies have documented the bed degradation caused by the two general forms of instream mining: (1) pit excavation and (2) bar ...

The removal of sand and gravel pollutes the river water and increases its temperature, which leads to reduced oxygen levels in the water. The study also suggests that the impact of in-stream mining, which means extraction of sand from the middle of the river, has a major impact on the flora and fauna.
