Short summary
Knickpoints represent localized steps along a river profile (e.g. waterfalls or rapids) that are commonly interpreted as the geomorphic response of river systems to external changes. We used a simple experiment to show that knickpoints may not only respond to external base-level change but are also able to self-organize. We highlight the effect of alluvial cover in delaying knickpoint formation and show that river bed strength controls both retreat velocity and geometry of knickpoints.
