(2021-05-06)Global climate change poses an imminent risk for humanity in the form of greater food insecurity, higher incidence of extreme weather events, and a severe loss of biodiversity. The increase in global mean temperature is ...
-
(2017-06-26)This thesis utilized the method of ground penetrating radar to investigate the structural geology of carbonate units in relation to the evolution of the island of Bonaire, Caribbean Netherlands. Two surveys were completed ...
-
(2013-05-28)This study characterizes the development and migration of blowouts within Padre Island National Seashore (PAIS). A combination of aerial photographs and Light Detection and Ranging (LIDAR) are used to track the migration ...
-
(Texas A&M University, 2006-08-16)Novel microwave transmitter and receiver circuits have been developed for implementing UWB (Ultra-Wideband) impulse radar imaging sensor operating in frequency band 0.2 to 4 GHz. with tunable operating frequency band. The ...
-
(2012-10-19)The study of mechanical energy and electrical energy dissipation in cementitious materials can lead to development of high damping concrete for structural applications, and new non-destructive testing techniques for use ...
-
(2011-02-22)The presence of fractures, joints and karst features within rock strongly influence the hydraulic and mechanical behavior of a rock mass, and there is a strong desire to characterize these features in a noninvasive manner, ...
-
(2021-12-10)Plant root phenotyping is a difficult task because of the opaque nature of soil, leading knowledge of root traits to lag behind above ground traits. While a large multiplicity of methods for observing roots have been ...
-
(2017-12-13)Ground penetrating radar (GPR) processing workflows commonly rely on techniques developed particularly for seismic reflection imaging. Although this practice has produced an abundance of reliable results, it is limited to ...
-
(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 ...
-
(2013-09-30)ABSTRACT Multisensor Geophysical Fusion for Improved Sub-surface Imaging at Camptown Cemetery, Brenham, Texas. (May 2014) Tate Gregory Meehan Department of Geology and Geophysics Texas A&M University Research Advisor: ...
-
(2014-08-14)Well-built roads with longer service life and lesser life cycle cost are the key to meet the desired target of satisfying the public without compromising the quality of roads. Roads that are constructed and built with poor ...
-
(2014-11-14)Rail tunnel linings are currently visually inspected and hammer sounded on all structural elements at random locations or where visual inspection shows the need for it. These methods are good; however, there will not always ...
-
(2016-04-27)The variability of soil depth at the catchment scale is an essential input for environmental modeling. If the model requires high resolution inputs, the inherent variability of soil depth in granitic and forested regions ...
-
(2018-05-04)Predictive analytics have traditionally been used to anticipate academic standing in college students using variables such as the American College Test (ACT) scores and/or School and College Ability Test (SAT) scores, ...
-
(2019-07-19)The application of biochar soil amendments has been proposed as a strategy of mitigating global carbon emissions and soil organic carbon loss. Biochar can provide additional agronomic benefits to cropping systems, including ...
-
(2017-07-21)From its discovery in 1921, the Odessa Meteorite Crater has interested researchers and mining companies who had initially hoped to locate a buried mass of meteoric iron. To find the impactor, a major geologic study of the ...
-
(2016-07-01)A multi-azimuth and multi-polarization ground penetrating radar (GPR) survey is carried out to help characterize a fractured fault zone located in Mason County, Texas. A total of 36 lines were acquired on and near the fault ...
-
(2009-05-15)Rock glaciers are dynamic landforms and, as such, exhibit interesting and welldeveloped structural features, which translate to surface morphology in the form of ridges and furrows. These distinguishing features have led ...
-
(2010-07-14)Landslides are one of the most dangerous geological hazards. In the United States, landslides cause a damage of $ 3.5 billion and kill 25 to 50 people annually. Shallow landslides occurring near any transportation facilities ...
