An Assessment of Environmental Impacts of Sand and Gravel ...

The increase in demand for sand and gravel for construction purposes has placed immense pressure on sand and gravel resources. Sand and gravel mining is a direct and obvious cause of environmental degradation (Kondolf, et al., 2008). The demand for gravel is rising because its importance and role in construction is indispensible.

The sand-deposition impact of artificial gravel beds on ...

Gravel beds can prevent sand-dust emission and weaken sand-dust flux. We used wind-tunnel experiments and field observations on artificial gravel beds above the Mogao Grottoes to quantify their impact. In the report, we identified a significant correlation between gravel roughness and its ability to trap wind-transported sand.
