Mining Gravel and Protecting Streams
More than 500 in-stream mining sites exist in Missouri. Considering the potential harm any one gravel mining operation can cause, it is important that gravel mining occur only with proper safeguards. Missouri's streams are vulnerable to huge problems caused by gravel mining. These waterways have formed within their valleys over thousands of years.
THE MANAGEMENT OF GRAVEL EXTRACTION IN ALLUVIAL …
A case study of the Avon River in Gippsland, southeastern Australia, demonstrates the impacts of commercial sand and gravel extraction from alluvial rivers. The Avon River has a long history of channel instability related in part to its recent change of course by avulsion and in part to destabilization driven by human activities in the channel. Contributing to this …

Sand Mining and Strategies for Its Management
Sand-and-gravel mining in stream channels and mining of sand in the active sand dunes or beach can damage structures built in the coastal areas and river bank by counter effect. Several studies have documented the bed degradation caused by the two general forms of instream mining, viz. pit excavation and bar skimming.

In-stream Sand and Gravel Mining
Sand and Gravel Mining - PUB2813. Personal Gravel Mining. The department does not require a Commercial Gravel Mining permit for personal use only, as identified in the regulations at 10 CSR 40-10.010(2)(B)1. However, personal use gravel mining may be regulated by U.S Corps of Engineers (USACE) under Section 404 of the Clean Water Act.
Towards Management and Regulation of Gravel Mining in …
Gravel extraction from a natural streambed combined with changes in water resource usage may induce modifications of a stream's sediment transport characteristics. Reduced transport capacity and river bed overdraft can bring a system off its natural equilibrium, resulting in decreased sediment replacement rates downstream from the extraction area, which in turn may affect …

Effects of Dams and Gravel Mining on River Channels
Floodplain gravel pits have the potential to become wildlife habitat upon reclamation, but may be captured by the active channel and thereby become instream pits. Management of sand and gravel in rivers must be done on a regional basis, restoring the continuity of sediment transport where possible and encouraging alternatives to river-derived ...
