IMPACT OF SAND DREDGING AND SILT EXTRACTION ACTIVITY ON RIVER AND ITS CHARACTERISTICS : A REVIEW

The present research work highlights the influences of sand dredging and extensive silt quarry ing activity on rivers. The sand dredging activity and its impact on the river processes and other river environment ha ve discussed in the present review paper. It has seen that most of the rivers and their processes are highly degraded and altered due to these activities. In India and almost in the regions of Maharashtra, the ground water is decreasing and such activities also invited the problems of ground water depletion. The study also deals with the relationship between the se activities and river ecosystem.
