Impacts of Sand Mining on Environment – A Review
River Environment Impact of Sand mining Sand is vital for sustenance of rivers. The sand mining has several impacts on the river environment. Sand mining disturbs and completely remove the habitat from the mined zones. It leads to changes in its channel form, physical habitats and stone webs – the river‟s ecosystem. It also increases the velocity of flow in river which destroy flow-regime ...
Environmental effects of river sand mining: a case …
On an average, 11.73 million ty −1 of sand and gravel are being extracted from the active channels and 0.414 million ty −1 of sand from the river floodplains. The quantity of instream mining is about 40 times the higher than the sand input estimated in the gauging stations. As a result of indiscriminate sand mining, the riverbed in the storage zone is getting lowered at a rate of 7–15 cm y

Impacts of Sand Mining
Excessive instream sand mining is a threat to bridges, river banks and nearby structures. 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 ...
