| Abstract | When a bedrock river is perturbed by accelerating rock uplift the perturbation is not transmitted instantaneously to the whole landscape; the new base level information must first spread through the channel network to hillslopes. Under detachment-limited conditions the new base level information is spread via knickpoint retreat, the rate of which ultimately governs response times to perturbation and therefore landscape evolution. Yet, owing to difficulties with measuring rates of erosional processes, knickpoint retreat rates are not widely documented. |
