Instream Sand and Gravel Mining: Environmental Issues and
Abstract Sand and gravel are widely used throughout the U.S. construction industry, but their extraction can significantly affect the physical, chemical, and biological characteristics of mined streams.

Geomorphic and environmental effects of instream gravel mining
Instream gravel mining involves the mechanical removal of gravel and sand directly from the active channel of rivers and streams. Active channel deposits are desirable as construction aggregate because they are typically durable (weak materials having been eliminated in river transport), well-sorted, and frequently located near markets or on 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. / Rivers transport sediment from eroding uplands to depositional areas near sea level.

Geomorphic and environmental effects of instream gravel Sediment mining produces a large variety of physical, ecological, and environmental effects in alluvial rivers. From a morphological point of view, instream gravel mining alters the preexisting channel morphology and a local sediment deficit is produced (Rinaldi et al. 2005).In addition to the direct alterations of the river environment, instream On the Morphological Impacts of Gravel Mining: The Case of

Sand-and-gravel mining in stream channels and mining of sand in the active sand dunes or beach can damage structures built in the coastal areas and river bank by counter effect. Several studies have documented the bed degradation caused by the two general forms of instream mining, viz. pit excavation and bar skimming.The sand and gravel mining has become one of the largest mining sectors in southwest India, especially in Kerala state as the region is fast growing due to economic developments in the past 4–5 decades.

The effects of mining will be especially severe and difficult to reverse: (i) where material is extracted at a rate greatly exceeding the replenishment rate; (ii) in single-thread rivers, that are generally associated with relatively low rates of catchment sediment supply; (iii) in channelized reaches; (iv) where rivers are underlain by a thinAbstract We used an information-theoretic approach to examine the variation in detection probabilities for 87 Piedmont and Coastal Plain fishes in relation to instream gravel mining in four Alabama...Influence of Gravel Mining and Other Factors on Detection
