Offshore sand and gravel extraction involves the abstraction of sediments from a bed which is always covered with seawater. This activity started in the early 20th century in the mid-1920s, in the United Kingdom, but did not reach a significant scale until the 1960s and 1970s, when markets for marine sand and gravel expanded and dredging technology improved Fig. 1.

Because of the instability of sand and gravel, the pit face should never be allowed to get higher than 20 to 25 feet for safe extraction. For deposits of 65 to 100 feet, benches or steps are often used
Along with their uses in concrete, sand and gravel are also commonly used for landscaping, road bases and coverings, unpaved roads, fill, asphalt, roofing shingles, water filtration, and to provide traction on snowy and icy pavement. The Production Process. The weathering of rocks over many years produces sand and gravel naturally.
The extraction of sand and gravel from river beds, banks and floodplains is driven by human needs for raw materials for concrete, glass and paint making, and construction works. Direct extraction of alluvial material from river channels causes far greater impacts than floodplain extraction. According to Rinaldi et al. 2005, the effects of bed ...
