commercial sand mining has been carried out in a number of areas along the suriname coast, notably on braamspunt beach, a major turtle-nesting beach on the east bank of the suriname river, constructed by waves essentially from sand supplied in the past by the maroni river.
the effect of mining is compounded by the effect of sea level rise. any volume of sand exported from streambeds and coastal areas is a loss to the system. it is also a threat to bridges, river banks and nearby structures. sand mining also affects the adjoining groundwater system and the uses that local people make of the river.
mining. sand falls by gravity to the bottom. after washing, the sand is then sent to a surge pile where water adhering to the sand particles infiltrates back into the ground. from the surge pile the sand is sent to the dryer and screening operation where the sand is dried in a drum with hot air blasted into it.
the qsr results demonstrate that the response of river ecosystems to sand mining is complex, with no one simple cause–effect model applicable to all systems. channel incision is the most common physical change, but other responses are highly variable and linked to the inherent characteristics of the river system and other stressors.
sand mining involves extracting minerals and resources from the sea floor, either by dredging sand or lifting material in some other way. according to kasm (kiwis against seabed mining) the ironsands off the west coast of the north island of new zealand, are a unique geological and marine environment, currently in the crosshairs of global

sand mining has occurred in wisconsin for more than 100 years. recent growth in the petroleum industry has created a high demand for sand that can be used for hydraulic fracturing, a technique used to extract natural gas and crude oil from rock formations in other states. wisconsin has high-quality sand resources and, as a result, the dnr has

excessive instream sand-and-gravel mining causes the degradation of rivers. instream mining lowers the stream bottom, which may lead to bank erosion. depletion of sand in the streambed and along coastal areas causes the deepening of rivers and est...
another effect of sand and gravel mining is the loss of the protection provided by soil as it filters out pollutants (rutherford et al. 1992; kalbitz et al. 2000). removing the organic layer of soil found on the surface of sand and gravel deposits decreases the soil’s capacity to absorb contaminants and thus clean water as it passes through
