suspended sediments from sand mining sites, but the long term, indirect and cumulative effects of mining upon the food chain are harder to study, and have not really been tackled. To study sitespecific effects of instream mining would require careful measurement of mininginduced changes to baseline conditions (Kondolf et al., 2002).
The environmental impact of reservoirs comes under everincreasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases.. Dams and reservoirs can be used to supply drinking water, generate hydroelectric power, increase the water supply for irrigation, provide recreational opportunities, and flood control.
