Testing the Origins of the Blue Ridge Escarpment
Long, linear, high-relief escarpments mark many of the world's passive margins. These Great Escarpments have been interpreted to be the result of isostatic flexure, parallel slope retreat, and divide migration which accompanies rifting. It is unclear whether all these escarpments share this origin. …

Dynamic river networks drive landscape change and biological evolution
… topographic evidence for divide motion along the Blue Ridge Escarpment in the Appalachian Mountains. In Chapters 3-4 I investigate the connections between geomorphic processes and biological evolution. In Chapter 3, I build a coupled model that simulates river network reorganization in addition to …

Evolution of transient topography on passive margins: A study of landscape disequilibrium in the southern Appalachian Mountains
… flowing across the elevated, slowly eroding Blue Ridge Plateau relative to the present Atlantic and landward interior base levels. Gravel deposits confirm that repeated capture of landward-draining Plateau streams by Atlantic basin streams, whose immediate base level is 250-300 m lower, …
