1994-8-1  The Interagency Instream Gravel Mining Task Force consists of representatives of state agencies involved in permitting and reviewing instream mining. Its purpose is to coordinate efforts among agencies, to explore ways of streamlining the permitting process, and to examine possible statewide policies for instream mining, such as establishing uniform standards for monitoring cross section surveys.

Instream operators also fall under the jurisdiction of other agencies, such as the US Army Corps of Engineers and the California Department of Fish and Game, but these agencies lack resources and a consistent approach to evaluate and mitigate the environmental effects of instream mining. Instream gravel mining can be properly addressed only by comprehensive environmental planning that

Geomorphic and environmental effects of instream

1994-4-1  Instream gravel mining involves the mechanical removal of gravel and sand directly from the active channel of rivers and streams. Active channel deposits are desirable as construction aggregate because they are typically durable (weak materials having been eliminated in river transport), well-sorted, and frequently located near markets or on transportation routes.

Fisheries biologists often find themselves involved in the complex environmental and regulatory issues related to instream sand and gravel mining. This paper provides an overview of information presented in a symposium held at the 1997 midyear meeting of the Southern Division of the American Fisheries Society in San Antonio, Texas, to discuss environmental issues and regulatory procedures related to instream mining.

The second objective was to link potential habitat impacts to recommended monitoring and adaptive management strategies that are incrementally more sophisticated as expected impacts increase. Only by excluding gravel extraction from the river corridor can future mining impacts to salmonid habitat be avoided.

Modeling Channel Response to Instream Gravel Mining

2018-9-25  This paper aims to simulate the channel response to instream gravel mining. First, the feasibility of the two-dimensional depth-averaged model (CCHE2D) in modeling mining-induced bed change was examined by comparing the calculated results to the data measured in two sets of published laboratory experiments. Thereafter, the two dimensional
