  • An Assessment of Environmental Impacts of Sand and Gravel

    Sand and gravel mining refers to the actual process of removal of sand or gravel from a place of occurrence. The increase in demand for sand and gravel for construction purposes has placed immense pressure on the environment where these resources occur. Miners employ different methods of extraction along river channels and their flood plains. Using environmental impact assessment guidelines, a

    01.08.1994· Environmental costs of instream mining have been externalized, so instream sources may appear to be cheaper than alternatives that involve more processing or transportation. If the costs of bridge failure and losses of riparian and aquatic habitat were factored into the costs of instream sources, alternative sources would be more attractive. By bearing the costs of impacts to bridges from

  • Geomorphic and environmental effects of instream gravel

    01.04.1994· 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.
