Environmental impact of mining Wikipedia

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have

Human causes of coastal erosion MarineSpecies Introduced

Sand mining in rivers is a major cause of coastal erosion in many countries. Sand mining in a river lowers the river bed, causes bank erosion and reduces the supply of sand to the coast. There are five components in the sediment balance for a degrading river section, schematically represented in Fig.7.

Coastal Systems: How Erosion, Transportation and

The processes of erosion, transportation and deposition occur as a result of differing wave and current energy. Where marine energy is high, erosion, removal and transportation is more likely to take place. Where energy is reduced, deposition of transported material is more of a feature. It is important to recognise that the wave type affects the process that occur.
