dredging rivers and lakes or mining (quarrying) inland deposits for sand destroys and pollutes natural habitats, including forests, farmland, and commercial fisheries. streambed mining may also lead to streambed and bank erosion as well as lowering of groundwater tables, leaving nearby drinking-water wells and wetlands dry.
in stream, sand mining as well as flood plain mining is most prevalent in these areas (fig.2).it was reported during the investigation that river sand accumulation was a problem in these three selected sites before 30 years, as it caused frequent floods in the basinal area and the flood that occurred in 1978 is an example which made a severe damage in the catchments.
