Abstract

The AA. present a testable framework for the study of fluvial incision into bedrock that combines theory with field observation. They quantify a simple erosion law by measuring drainage areas and slopes on both principal channels and tributaries. The results suggest three general mechanisms by which bedrock channels erode: 1) vertical wearing of the channel bed due to stream flow; 2) scour by periodic debris flows; and 3) knickpoint propagation. Consequently, application of a single erosion law to the entire bedrock channel network may be inappropriate
