Comparative Lineament and Geomorphic Analysis of Chaotic Terrains and Noctis Labyrinthus, Mars
<p>Noctis Labyrinthus (NL) is an extensional trough network connecting the Tharsis rise and Valles Marineris on Mars. Chaotic terrains are a group of polygonally-fractured surface features commonly associated with subsidence due to rapid fluid loss within the subsurface. Polygonal surface patterns …

Geomorphic Analysis of A Rural Fluvial System During Pre-Dam Removal Conditions: A Case Study In Eastern Virginia
… a comprehensive (spatially and temporally) analysis of the pre-dam removal fluvial system. This thesis investigates the linkages between the physical and chemical systems upstream and downstream of two small dams in eastern Virginia planned for removal. Data were collected during twelve …

Banking on offsets: a political ecological and eco-geomorphic analysis of Section 404 compensatory stream mitigation banking in Illinois and Missouri
… is composed of four separate analyses. Each analysis provides additional insight into the logics and subsequent biophysical outcomes of Section 404 compensatory stream mitigation banking regulators and participants in Illinois and Missouri. First, this dissertation explains the social …

Evaluation of Late Mesozoic and Cenozoic Tectonism: Atlantic Inner Coastal Plain Margin Near Richmond, Virginia
<p>A combined geologic, geophysical, and geomorphic analysis of the Virginia Inner Coastal Plain margin near Richmond was conducted to investigate the presence of basement structures and to evaluate their influence on the overlying sedimentary package and present-day landscape. Basement structures …

Eolian Landscape History and Prehistoric Dune Farming in Petrified Forest National Park: A Geoarchaeological Approach to Understanding the Long-Term Use of a Marginal Landscape
… of widespread dune farming agriculture. Soil geomorphic analysis and optically stimulated luminescence dating document discrete periods of eolian activity in the study area. The oldest eolian activity dates to ca. 16,000–11,000 B.C., and is expressed as stable dunes on upland landscape …

Evaluating the Controls of Neogene Exhumation in the Tropical Northern Andes (colombia)
… most biodiverse places on earth. I used a geomorphic analysis to characterize the topography of the Western and Central Cordilleras of the Northern Andes. The topographic analysis was supplemented with erosion rate estimates based on gauged suspended sediment loads and river incision rates …

Understanding Himalayan denudation at the catchment and orogen scale
… and vegetation density in the Himalaya. An analysis of 136 published 10Be denudation rates from along strike of the revealed that median denudation rates do not vary considerably along strike of the Himalaya, ~1500 km E-W. However, the range of denudation rates generally decreases from west …

THE PACE AND TIMING OF CHANGING LANDSCAPES AS VIEWED THROUGH COSMOGENIC RADIONUCLIDES: SYNTHETIC AND REAL EXAMPLES FROM THE CENTRAL ANDES AND AMAZONIA
… for the landscape and species evolution. Geomorphic analysis of fluvial metrics derived from a digital elevation model revealed a signal of base level fall in the Negro River valley, consistent with a modification of the valley or the Negro River channel itself. Given the timing of burial …

Geospatial Analyses of Seismic Hazards and Risk Perception in Libya
… to better understand earthquake hazards, related geomorphic features, and the current evolution of Libyan perceptions of seismic risk. The first article developed a baseline of past and current seismic inventory in Libya, which represented an assessment of Libya seismic hazard by translating, …
