WebJun 11, 2024 · As defined by Hungr et al. ( 2001 ), an established channel or regular confined path is the key requirement for initiating debris flows as it could effectively carry surface water flow and maintain large flow depth.

WebAbout 12 of the debris-flow channels were located in the lower half of Weldon Gulch upslope from Alpine, which is on a debris fan at the mouth of the Gulch. Most of these channels were deeply incised by the flows, and many of the resulting oversteepened channel banks are now failing and beginning to refill the channels with sediment. WebAug 13, 2016 · Channel incision has major adverse impacts on stream corridor ecosystems. As channels deepen and widen, pool habitats are lost, riparian vegetation is destroyed, and woody debris becomes less common within the channel. Baseflows are characterized by extremely shallow flow over shifting sand beds.
