A knickpoint is a term in

geomorphology to describe a

location of a river or channel

where there is a sharp change

in channel slope, such as a

waterfall or lake. Knickpoints

reflect different conditions and

processes on the river often

caused by previous erosion

due to glaciation or variance in

lithology.

Formation

Knickpoints are formed by the

influence of tectonics, climate

history, and/or lithology.[1] For

example, uplift along a fault

over which a river is flowing

will often result in an unusually

steep reach along a channel,

known as a knickzone.

Glaciation resulting in a

hanging valley are often prime

spots for knickpoints. If

lithology of the rock varies,

such as shale amongst igneous

rock, erosion will occur more

steadily in the softer rock than

the surrounding.
