The effects of river sand mining can also be seen at the coast where the lack of sand replenishment can cause beaches and dunes to erode faster and therewith offer less protection against storm surges, tsunamis and sea level rise (Shaghude et al., 2012 ). 5. Effects on the biological environment.It could, for example, prevent recharge of a stratigraphically high aquifer (Padmalal and Maya, 2014). There have been many reports, from various regions across the globe (e.g. India (Padmalal et al., 2008), Iran (Zolghadr et al., 2021), Nigeria (Ako et al., 2014), Australia (Stow and Chang, 1987)), where the riverbed morphology was altered Migration of sand mining pit in rivers: An experimental,
