Recent growth of the construction industry has fuelled the demand for sand, with considerable volumes being extracted from the world’s large rivers. Sediment transport from upstream naturally replenishes sediment stored in river beds, but the absence of sand flux data from large rivers inhibits assessment of the sustainability of ongoing sand mining. Here, we demonstrate that bedload (0.18 ± 0.07 Mt yr −1 ) is a small (1%) fraction of the total annual sediment load of the lower Mekong River… 
Sand mining far outpaces natural supply in a large alluvial river
Abstract. The world's large rivers are facing reduced sediment loads due to anthropogenic activities such as hydropower development and sediment extraction. Globally estimates of sand extraction from
Long-term sediment decline causes ongoing shrinkage of the Mekong megadelta, Vietnam
The new geological reconstruction of 2500-years of delta shoreline changes show that serious coastal erosion actually started much earlier, and natural mitigation would require substantial increases in sediment supply well above the pre-1990s levels.
Effects of riverbed incision on the hydrology of the Vietnamese Mekong Delta
The hydrogeomorphology of the Vietnamese Mekong Delta (VMD) has been significantly altered by natural and anthropogenic drivers. In this study, the spatiotemporal changes of the flow regime were
Legacy‐micropollutant contamination levels in major river basins based on findings from the Rhône Sediment Observatory
For more than half a century, chemical contamination has progressively spread to all the large river basins. Large river outlets integrate multiple anthropogenic pressures in watersheds, making them
Anthropogenic Effects on the Contemporary Sediment Budget of the Lower Rhine‐Meuse Delta Channel Network
Deltas and estuaries worldwide face the challenge of capturing sufficient sediment to keep up with relative sea‐level rise. Knowledge about sediment pathways and fluxes is crucial to combat adverse
Strategic basin and delta planning increases the resilience of the Mekong Delta under future uncertainty
An integrated assessment of the Mekong Delta finds that 23 to 90% of this unusually productive delta might fall below sea level by 2100, with the large uncertainty driven mainly by future management of groundwater pumping and associated land subsidence.
The Unsustainable Use of Sand: Reporting on a Global Problem
Sand is considered one of the most consumed natural resource, being essential to many industries, including building construction, electronics, plastics, and water filtration. This paper assesses the
Establishing sustainable sediment budgets is critical for climate-resilient mega-deltas
Many of the world’s major river deltas face a sustainability crisis, as they come under threat of increases in salinity and the extent of tidal zones forced by combinations of sea-level rise, changes


Linking rapid erosion of the Mekong River delta to human activities
Shoreline erosion is an additional hazard to the integrity of this Asian mega delta now considered particularly vulnerable to accelerated subsidence and sea-level rise, and will be exacerbated by future hydropower dams.
Reappraisal of sediment dynamics in the Lower Mekong River, Cambodia
The Mekong Basin in southeast Asia is facing rapid development, impacting its hydrology and sediment dynamics. Although the understanding of the sediment transport rates in the Mekong is gradually
Dams on the Mekong: Cumulative sediment starvation
The Mekong River, largely undeveloped prior to 1990, is undergoing rapid dam construction. Seven dams are under construction on the mainstem in China and 133 proposed for the Lower Mekong River and

Management of sand and gravel in rivers must be done on a regional basis, restoring the continuity of sediment transport where possible and encouraging alternatives to river-derived aggregate sources.
Fluvial sediment supply to a mega-delta reduced by shifting tropical-cyclone activity
This study shows that changes in tropical-cyclone climatology affect trends in fluvial suspended sediment loads and thus are also key to fully assessing the risk posed to vulnerable coastal systems.
Sand mining effects, causes and concerns: A case study from Bestari Jaya, Selangor, Peninsular Malaysia
The assessment of water quality shows that water has been highly polluted immediately downstream of station at Selangor River due to high concentrations of suspended particles, and transport modeling and water quality analyses performed have identified major physical environmental impacts.
