Mechanics of river and waterfall incision into rock

Fluvial erosion into bedrock is one of the fundamental drivers of landscape evolution. Most of our work has focused on waterfall or knickpoint erosion, including the formation of amphitheater headed canyons.   Ongoing work includes a series of field and flume experiments designed to develop a process based model for the retreat of waterfalls by plunge pool erosion. This includes rappelling into active plunge pools.
