A Dendrogeomorphological Assessment of the Donald Duck Landslide Complex, Grand Mesa, Colorado
(2016-10-06)Grand Mesa, Colorado exhibits numerous dynamic geomorphologic phenomena, including ancient and currently active features of mass movement. The dense, basaltic mesa top that makes up Grand Mesa is underlain by weak Tertiary ... -
A comparison of clovis caches
(Texas A&M University, 2006-04-12)The Clovis caches in this study consist of assemblages of tools left behind in an area either for future use or as ritual offerings. Clovis caches are the earliest of such assemblages known in North America. This research ... -
Coupling of Backbarrier Shorelines to Geomorphological Processes
(2013-08-14)Recent evidence suggests that backbarrier structure may act as an historical record of island development, and that backbarrier shorelines can be used as a proxy of an island’s past and future transgressive response to ... -
Desert pavement morphology and dynamics, Big Bend National Park, Texas
(2009-05-15)Desert pavements consist of a one- to two-layer thick surface armory of stones overlying finer, virtually stone-free material which often adopts the appearance of a meticulously tiled mosaic. They cover half of the arid ... -
Evaluating Channel Migration of the Lower Guadalupe River: Seguin, TX to the San Antonio River Confluence
(2016-08-18)On Earth, rivers are found meandering across the landscape. To accommodate dynamic flow regimes and sediment loads, rivers are in constant adjustment within the channel and adjacent valley. Extreme floods as well as base ... -
Forms and Distributions of Hurricane Ike Backflow and Scour Features: Bolivar Peninsula, Texas
(2011-08-08)The storm surge from Hurricane Ike inundated Bolivar Peninsula as well as pooled up (~4 meters above sea level) in the Galveston Bay System behind Bolivar. After the hurricane passed, this water flowed back over the ... -
Geoarchaeological Investigations into Paleoindian Adaptations on the Aucilla River, Northwest Florida
(2012-07-16)This dissertation addresses how Paleoindians used the karst drainage of the Aucilla River in northwestern Florida during the Pleistocene/Holocene transition (approximately 15-10,000 14C yr B.P.). I take a geoarchaeological ... -
Influence of Bark-Beetle-Induced Tree Mortality on Slope Erosion in the San Juan Mountains of Ouray, CO, USA
(2017-07-14)Degradation of the natural environment has resulted from the destruction by bark-beetles at various geographic locations around Earth. Presently, widespread tree mortality is occurring in the San Juan Mountains of southwestern ... -
A model for the development of a lobate alpine rock glacier in southwest Colorado, USA: implications for water on Mars
(Texas A&M University, 2004-09-30)Rock glaciers play a significant role in the alpine debris transport system. For practical and engineering considerations, identifying the internal structure and its relationship to surface characteristics is significant ... -
Motion and evolution of the Chaochou Fault, Southern Taiwan
(Texas A&M University, 2005-11-01)The Chaochou Fault (CCF) is both an important lithologic boundary and a significant topographic feature in the Taiwan orogenic belt. It is the geologic boundary between the Slate Belt to the east, and the Western Foothills ... -
Surf Zone Sediment Size Variation, Morphodynamics, and Hydrodynamics during Sea/Land Breeze and El-Norte Storm in Sisal, Yucatan, Mexico
(2015-08-06)This study compares the effects of a mesoscale pressure system (i.e., cold front: referred to as El-Norte) and local pressure systems (land and sea breezes) on the hydrodynamics, beach profile, and particle size distribution ... -
System Controls on the South Texas Sand Sheet
(2017-05-02)Semi-stabilized dune systems are important indicators of Quaternary drought variability across central North America. The South Texas sand sheet (STSS) is the southernmost relict dune system in central North America and ...
