During floods, the river tries to cut across meanders, runs through the mines and carries sand downstream. The authors say this can lead to: River bed degradation. Bank erosion. Channel widening. Infrastructure damage or destruction. Loss of riparian vegetation. Habitat damage. Degradation of water quality.

Sand-and-gravel mining in stream channels and mining of sand in the active sand dunes or beach can damage structures built in the coastal areas and river bank by counter effect. Several studies have documented the bed degradation caused by the two general forms of instream mining, viz. pit excavation and bar skimming.

The high resolution of the images, and the ability of repeated flying over a river or torrent/stream reach, allows the frequent and detailed monitoring of large areas at a relatively low cost. This methodology can help the authorities responsible to quickly and easily identify illegal gravel and sand mining sites in the river/stream/torrent.

Other Sand Mining Methods. Sand dunes can also be mined by dredging or hydraulic methods. This involves a high pressure jet of water to wash the sand into a pond where it is pumped to a storage pile or tank. Where sand is present in the form of loose sandstone, drilling and blasting are necessary. The blasting reduces the sandstone to …

In-stream mining also impacts diversity. When the in-stream mining removes or alters the river and riverbank habitat, the number of individual species that once lived in those habitats declines (Bruce, 2009).
