Selected research on woody encroachment, glacial cross-valley profiles, and mass-movement disturbance regime landscapes by Brandon Jeffery Weihs B.S., University of Nebraska, 2007 M.A., University of Nebraska, 2009 AN ABSTRACT OF A DISSERTATION submitted in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY Department of Geography & Geospatial Sciences College of Arts and Sciences KANSAS STATE UNIVERSITY Manhattan, Kansas 2020 Abstract This dissertation is a series of stand-alone journal articles and reports produced during my tenure as a Ph.D. student. All of these articles are peer-reviewed outside the Kansas State University system, and one of them is published in Papers in Applied Physical Geography, a peer-reviewed journal. The following dissertation is itemized by chapters that include these pieces; Woody encroachment of a riparian corridor in a tallgrass prairie: dendrochronological evidence from Kansas, USA; Slope Failures and Cross-valley Profiles, Grand Teton National Park, Wyoming; Mass-movement Disturbance Regime Landscapes, Hazards, and Water Implications: Grand Teton National Park, Wyoming.
