Impacts of Sand Mining

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 skimming.

Sand Extraction - an overview | ScienceDirect Topics

Offshore sand and gravel extraction involves the abstraction of sediments from a bed which is always covered with seawater. This activity started in the early 20th century (in the mid-1920s, in the United Kingdom), but did not reach a significant scale until the 1960s and 1970s, when markets for marine sand and gravel expanded and dredging technology improved (Fig. 1).
