Abstract

Sand is a critical natural resource used in the construction sector, in land reclamation and coastal protection schemes. Global consumption of aggregates is estimated to be c. 40 billion tonnes a year (Peduzzi, 2014) a large proportion of which is derived from fluvial sediment sources. This figure exceeds the mass of sediment delivered annually to the global ocean (Milliman and Syvitski,
1992). Moreover, with urban populations projected to rise substantially over the next 20 years (UN, 2019), unsustainable extraction of alluvial sand represents a critical threat to the morphological and ecological integrity of rivers.
