In geomorphology, a knickpoint or nickpoint (from the German Knick, a sharp turn) is part of a river or channel where there is a sharp change in channel bed 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.
