Soil and Sand Mining: Causes, Consequences and Management
Sand mining is the process of removal of sand and gravel where this practice is becoming an environmental issue as the demand for sand increases in industry and construction. Topsoil is an essential component in abandoned mines for growth of vegetation and has to be preserved for post-mining land reclamation. Physico-chemical parameters and concentration of heavy

1. IMPACTS OF SAND MINING - San Diego State University
Sand mining also affects the adjoining groundwater system and the uses that local people make of the river. Instream sand mining results in the destruction of aquatic and riparian habitat through large changes in the channel morphology. Impacts include bed degradation, bed coarsening, lowered water tables near the streambed, and channel instability. These physical

Seabed Mining - The Ocean Foundation
Seabed Mining (SBM) is a growing industrial field that involves extracting submerged minerals and deposits from the sea floor. To date, mining for sand, tin and diamonds has been generally limited to shallow coastal waters. Seabed Mining (SBM) should be distinguish from Deep Sea Mining (DSM) that occurs at a depth of 200 meters and greater.
