Removing sediment from rivers causes the river to cut its channel through the bed of the valley floor (or channel incision) both upstream and downstream of the extraction site. This leads to coarsening of bed material and lateral channel instability. It can change the riverbed itself. Incision can also cause the alluvial aquifer to drain to a lower level, resulting in a loss of aquif.
