Study of Sand Mining and Related Environmental Problems - Gravel Mining

Abstract 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.Impacts of Sand Mining - Three issues of sustainable management ... Instream mining lowers the stream bottom, which may lead to bank erosion. ... Excessive instream sand mining is a threat to bridges, river banks and nearby .... Instream sand mining activities will have an impact upon the river's water quality. Read more

Preliminary Guidance document for Authorisation and - Sand mining spirals out of control

Extreme instream sand mining is causing degradation of rivers. It is also lowering the stream bottom, which can ultimately lead to bank erosion. Diminution of sand in the streambed and along the coastal areas can cause deepening of rivers and estuaries, and …that instream mining is the prevalent type of sand mining in the study area and accounts for about 51% of the sand mining operations along Nzhelele River whilst flood plain mining only constitute 44%. A very small percentage (5%) of the operations employ both instream and floodplain mining in the study area.
