Sand in Demand: Trapped behind Dams. Gomby, G. Science, 358(6360):180, October, 2017.
doi  abstract   bibtex   
[Excerpt] [...] Estimates of total sediment entrapment behind large dams over the past half-century may be on the order of 100 billion metric tons, or 30\,% of the total potential global flux [...] United Nations estimates project that 66\,% of the world's population will be urban by 2050, an increase of 2.5 billion people [...]. If this urbanization is the primary driver of accelerated sand appropriation, demand will markedly increase. It is possible that reservoirs and impoundments will therefore be both a contributor to sand scarcity as well as a possible solution. [...]
