However, the impacts of sand and gravel mining could also cause disturbances to ecological balance, since it is closely related to land use change and river degradation, besides causing conflicts3.2.1 Instream Mining. Extraction of sand and gravel from the active channel of a river is called instream sand mining. Instream (in-channel) sand usually requires less processing than any other sand sources. Instream sand mining takes place in many fluvial subsystems—bars, point bars or even active channels.River Sand Mining and Mining Methods SpringerLink

ASSESSMENT OF SOCIOLOGICAL AND ECOLOGICAL IMPACTS OF SAND AND GRAVEL
Sand and gravel mining has been one of the serious environmental problems around the globe in recent years. This often results in land degradation, loss of agricultural lands and biodiversity as well increased poverty among people. In order to address these problems, pragmatic and explicit laws and regulations have to be developed by countries in a This major impact is accompanied by loss of habitat, noise, dust, blasting effects, erosion, sedimentation, and changes to the visual scene.
