See also Hill et al. (2008) Geomorph. 95, 3–4 on the Grand Canyon, USA. From: headward erosion in A Dictionary of Geography ». Headward erosion can put streams in different drainage basins in direct competition. The stream undergoing faster headward erosion eventually snares one or more tributaries from the other stream in a process known as stream capture or stream piracy. Head-ward erosion is the process by which a river erodes its source region, seemingly lengthening its channel in a direction opposite to that of flow. When water falls on a planer surface, it has a tendency to flow along slope in form of an oscillating stream.
another experiment on Scripps beach headward. ( ˈhɛdwəd) adj. (Physical Geography) (of river erosion) cutting backwards or upstream above the original source, which recedes. adv. (Physical Geography) a variant of headwards. Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 1994, 1998, 2000, 2003, 2006, 2007, 2009, 2011, 2014. Headward erosion is continuing at a low rate, due to the instability of the rock face related to significant fracturing and the overhang due to erosional undercutting in the underlying clay-rich marl left behind after the flood.
Headward erosion causes the river channel to become longer because erosion towards the source of the river occurs.
HEADWARD EROSION meaning - HEADWARD EROSION definition - H Head-ward erosion is the process by which a river erodes its source region, seemingly lengthening its channel in a direction opposite to that of flow. When water falls on a planer surface, it has a tendency to flow along slope in form of an oscillating stream. Changes in sediment conveyance can also change systematically as a result of headward erosion of rills and gullies, changes in runoff due to storm water management, or related factors (Faulkner and McIntyre 1996).

Oct 6, 2009 Bars were built by deposition of coarse sediment eroded from and was caused by headward erosion rather than bar migration into a chute. Nov 27, 2015 On its slopes, gullies show young (geologically recent) headward erosion, which is the lengthening of the gully in the upslope direction. Gully erosion: Due to runoff of surface water causing the removal of soil with drainage lines. Once started, gullies will move by headward erosion or through the Dec 7, 2015 Headward erosion occurs for two reasons. First, it happens when the surface flow converging at the entrance to a channel has sufficient erosive Headward Erosion & Base Level Either faulting or a change in base level can disrupt stream equilibrium.
Headward erosion is erosion at the origin of a stream channel, which causes the origin to move back away from the direction of the stream flow, and so causes the stream channel to lengthen. [1] It can also refer to widening of a canyon by erosion along its very top edge, when sheets of water first enter the canyon from a more roughly planar surface above it, such as at Canyonlands National

This was caused by an erosion phenomenon that happened upstream of the waterfall; hydrologists and geologists are extremely concerned and almost two months ago warned authorities of the dangers
Headward erosion is erosion at the origin of a stream channel, which causes the origin to move back away from the direction of the stream flow, and so causes the stream channel to lengthen. Headward erosion is a fluvial process of erosion that lengthens a stream, a valley or a gully at its head and also enlarges its drainage basin.

At the place where the two kinds of erosion meet a knickpoint may be produced (Fig. 7A). In the study region, a large knickpoint occurs at Hukou (see Fig. 2D). Due to the sudden increase in gradient, a magnificent waterfall was produced indicative of energetic fluvial dynamics. another experiment on Scripps beach headward.
