Geotechnical assessment of sand for civil engineering in ...
Abstract. Sand used as aggregates for construction and other civil engineering works come from two types of artisanal mining in the western part of Cameroon. Sand is sourced from the river or open pit quarries suggesting their alluvial and elluvial origin. The suitability of sand used for civil engineering works in Western Cameroon was assessed.

2020-10-16 This study focuses on the mineralogy and bulk chemical composition of 19 sediment samples, collected from the Sanaga River bed, between Nanga-Eboko and the Atlantic Ocean in Cameroon, to infer provenance, weathering, and tectonic setting. The textural analysis revealed that these sediments are mainly coarse-grained sands. X-ray diffraction and heavy mineral analyses show

River Sand Mining Modelling and Sustainable Practice ...
Along the Kangsabati River in India, the consequences of sand mining are very serious. The construction of Mukutmonipur Dam (1958) on the river causes huge sediment deposition along the middle and downstream areas, these same areas are also intensely mined for sand (instream and on the flood plain).

Sand mining is stealing the minerals from Chinese rivers
2021-2-11 Unsustainable sand mining transforms the structure of rivers. By removing more than the river can naturally replace with the sediment it carries downstream, sand mining carves a deeper, narrower bed. This lowers the water level, speeds up flow and erodes banks – reducing the watershed’s capacity to absorb excess water during floods.
