Incising river
WebAug 23, 2012 · Since both the Yamuna and the Sutlej are Himalayan rivers, like the Indus rivers, they would have been incising their course within the past 10,000 years. The absence of any incised connection from the two rivers to the Ghaggar indicates that these connections did not exist during the past 10,000 years.

WebMay 1, 2016 · At large scale, landscapes result from the combination of two major processes: tectonics which generate the main relief through crust uplift, and weather which accounts for erosion. [] Our approach relies on the stream power equation introduced in geology for hydraulic erosion. 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. …
WebThe Le Sueur River watershed, in southern Minnesota, provides an ideal location for studying the impacts of agricultural land-use on erosion in an incising river.

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.
