Can River Sand Mining Be Sustainable?

mental impact of river sand mining could be significantly reduced. To see whether this is a possible course of action, alternatives to river sand mining were identified and assessed. The following alternative sources were highlighted: offshore sand, land­ based sand, dune sand and the use of quarry dust. EEPSEA is administered by Canada'sSouth Sumatera V. Lusiagustin and E. Kusratmoko Impact of,The effect of sand mining is not only degrading the water quality of the river but also changing the physical quality of the river, such as river bank erosion, river bank slump, changes in the river flow, and decreasing the river flow [3]. The flow pattern of the river and the riverbed mining materials such as sand can cause balance disorders in,
