Too much in stream sand-and-gravel mining ruins the rivers. In stream mining lowers the stream bottom, leading to erosion of the bank. Reduction of sand in the streambed and in coastal areas causes the deepening of rivers, estuaries and the swelling of river mouths and coastal inlets. It may also cause the saline-water to invade from the close sea.
