(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(2019-04-26)Studies on the complex flow dynamics of fluvial systems have benefited from recent advancements in hydroacoustic technology and post-processing and visualization software. The Velocity Mapping Toolbox (VMT) is one such ...
-
(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 ...
-
(2020-11-30)Rivers are thought to form fluvial terraces. The geneses of terraces depend on climatic changes because of the variations of riverbed slopes and sediment fluxes. Particularly, generating erosional-strath terraces requires ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(2021-05-07)Today, issues pertaining to anthropogenic and climate forcing are threatening available water resources on a global scale. For remote alpine regions whose primary water resources are seasonally derived from snowmelt and ...
-
Spatiotemporal Dynamics of Solar Radiation in the Himalaya: Topographic Forcing and Glacier Dynamics (2019-10-30)Glaciers across the Himalaya exhibit significant spatial variations in morphology and dynamics. Climate, topography and debris cover variations are thought to significantly affect glacier fluctuations and glacier sensitivity ...
-
(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 ...
-
(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 ...
