This review summarizes the use of High Resolution Stereo Camera (HRSC) data as an instrumental tool and its application in the analysis of geological processes and landforms on Mars during the last 10 years of operation. High-resolution digital elevations models on a local to regional scale are the unique strength of the HRSC instrument. The analys...
AbstractBethany M. NagidHistorical Shoreline Evolution as a Response to Dam Placement on the Elwha River, WashingtonMorphological changes of the Elwha River delta shoreline in Washington are analyzed from 1870-2015, revealing year-by-year as well as location-based geomorphological evolution. Change in the Elwha shoreline prior to the placement of t...
Oversteepened, convex segments of stream channels called knickpoints have been utilized as markers that commonly migrate upstream and delineate abrupt changes in erosional efficiency influenced by base-level fall, changes in rock strength, or strong spatial variations in discharge. Currently, few analyses based on DEMs enable discrimination among m...
The economic importance of coastlines highlights the need to understand how coasts evolve in response to changing climate. Prior work suggests that many of the estuaries in the northwestern Gulf of Mexico underwent large changes at 2.6, 4.8, and 8.2 ka. Twenty-eight vibracores, eight Geoprobe cores, twenty-eight radiocarbon ages, and twenty-five ki...
Although sea level has fluctuated repeatedly over the Pleistocene by up to 120 meters, how (or whether) this cyclic base level forcing impacts the development of bedrock river profiles in tectonically active settings is poorly understood. A major reason for this uncertainty is that bedrock river channels in unglaciated locations are typically burie...
Fundamental to the advancement of planetary geology is an understanding of the interaction between tectonic and aqueous processes on planetary surfaces. This dissertation examines this interaction within two geomorphologic processes: landslide emplacement, on Mars and on Earth, and the formation of seasonal slope features on Mars. Long-runout lands...
