Instream sand mining activities will have an impact upon the river''s water quality. Impacts include increased shortterm turbidity at the mining site due to resuspension of sediment, sedimentation due to stockpiling and dumping of excess mining materials and organic particulate matter, and oil spills or leakage from excavation machinery and .

impact of sand mining since the mining operations are often located in areas favorable for developing potable ground water. Sand mining results in the destruction of aquatic and riparian habitat through large changes in the channel morphology. Impacts include bed degradation, bed coarsening,

Suction mining was found to have the most impact on embryonic stages of fish, with juvenile and adult fishes more likely to avoid or survive passage through a suction dredge (Harvey amp; Lisle, 1998). Rempel and Church found that dry experimental bar scalping in the Fraser River, Canada, had no discernible impact on the local fish community.

#0183;#32;This study assesses the impact of sand mining on the morphology of Kano River channel. The river channel was divided into three sites consisting of site upstream of active mining site, active mining site and downstream of active mining. The upstream site was assumed to be unaffected by the mining activity. The mining site was an area of current active mining.
ing, the physical effects of instream gravel mining may include improved flood control and channel stability in rapidly aggrading riv ers. Instream mining also results in the de struction of aquatic and riparian habitat through large changes in channel morphology (Sandecki, 1989). Impacts described in the
