Geomorphic and environmental effects of instream gravel mining
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), wellsorted, and frequently loed near markets or on transportation routes.
