Regulatory and policy implications of sand mining

2019-7-4  Sand mining risks and associated impacts. Most sand mining impacts are associated with the removal of substratum material, alteration of the bottom topography, sediment composition, changes in depth and current strength, and the modification of hydrologic conditions (Allsopp et al. 2013; Uscinowicz et al. 2014). Rapid removal of sand reduces groundwater recharge and may result in premature failure
