WebAn incised river is defined as a river that is experiencing bed-level lowering. From the viewpoint of geomorphological process, mountain rivers either were or are incised rivers. … River incision is the natural process by which a river cuts downward into its bed, deepening the active channel. Though it is a natural process, it can be accelerated rapidly by human factors including land use changes such as timber harvest, mining, agriculture, and road and dam construction. See more River incision is the narrow erosion caused by a river or stream that is far from its base level. River incision is common after tectonic uplift of the landscape. Incision by multiple rivers result in a dissected landscape, for … See more Groundwater level drop As a channel bed drops, the water in the surrounding aquifer runs into the stream, lowering the water table. This modifies the flow regime of a stream, and can lead to a large reduction in summer flows.
