Encyclopedia of Geomorphology
Knickpoint (nickpoint) refers to a substantially steepened section of a stream long
profile. In cyclic interpretations of landscape (Davis 1899) knickpoints carried a
new 'cycle' of erosion inland replacing an older, more elevated low relief surface
...

Tectonics, Climate, and Landscape Evolution
We observed 12 knickpoint events during the time that we measured knick- point
and hillslope failure locations. During this observational time (13 h), base level
dropped 14.5 cm. While knickpoint heights varied, and most knickpoints initiated
...

Rivers Over Rock: Fluvial Processes in Bedrock Channels
In a given interval of time, the lower gradient portions of the knickpoint will
propagate faster and hence travel further upstream. With time the shape of the
upper portion of the migrating knickpoint becomes smeared out and diminished
in overall ...

Knickpoint Migration and Landscape Evolution on the Roan ...
Downstream of knickpoints, canyon width mirrors canyon relief, suggesting cliff retreat depends on channel incision.
Maureen Mason Berlin, 2009
Overall, this book focuses on the current understanding of the dynamic interplay between surface processes and active tectonics.

formation and headward retreat of a knickpoint can thus determine the extent to
which a bedrock channel reach is serving as a local base level limiting incision
along upstream alluvial reaches. Although knickpoints are commonly regarded
as ...

This oversteepened reach immediately downstream of the knickpoint had a 10%
slope which was significantly steeper than the adjacent reaches. A total of 5 runs
were performed with different slopes in the upstream and downstream reaches ...
11c, d), a clear knickpoint, indicated by a peak on the DS plot, has formed at the
downstream edge of the basalt as a result of the rate differential between incision
on the country rock and on the basalt. This incision rate differential results in a ...

Geomorphology: The Mechanics and Chemistry of Landscapes
Knickpoint migration In some instances, lowering of the channel bedrock is
accomplished by upriver migration of discrete steps, or knickpoints, in the profile.
Here a knickpoint is defined as a steep reach sandwiched between two low-
gradient ...

Megaflooding on Earth and Mars
In the experience of the authors, inner channels almost always possess a
knickpoint at their head, implying that even extensive inner-channel formation
occurs through knickpointretreat(Baker, 1973b;Wohl, 1993;Wohletal., 1994),
although an ...
