SORPTION-MEDIATED CHEMICAL PROCESSES FOR THE VERSATILE TREATMENT OF PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) IN COMPLEX MEDIA
(2020-08-10)
In recent years, per- and polyfluoroalkyl substances (PFAS) have gained notoriety due to environmental and health concerns. These molecules are chemically stable which contributes to their persistence in biological systems ...
Analyze the effect of urbanization and development over the flow regime and river channel hydraulics of the Big Bear creek channel
(2023-06-06)
This thesis focuses on investigating the influence of urbanization and development on flow regime and river channel hydraulics in the Bear Creek watershed, Texas using a comprehensive set of hydrologic and 1D/2D coupled ...
IMPROVING FLOOD FORECASTING USING CONDITIONAL BIAS-AWARE ASSIMILATION OF STREAMFLOW OBSERVATIONS AND DYNAMIC ASSESSMENT OF FLOW-DEPENDENT INFORMATION CONTENT
(2020-12-22)
Accurate forecasting of floods is a long-standing challenge in hydrology and water management. Data assimilation (DA) is a popular technique used to improve forecast accuracy by updating the model states in real time using ...
Development of a Structural Design Methodology for Cementitious Sprayed Applied Pipe Linings in Gravity Storm Water Conveyance Conduits
(2020-09-04)
Culverts are important components of the highway infrastructure. They form passageways through the embankment to convey storm water. Culverts are structurally designed to support superimposed earth loads or other fill ...
Change in Sedimentation Regime due to Bridge Construction Activities: A Field Study at FM 2478 Bridge Over Wilson Creek, McKinney, Texas
(2021-12-20)
Bridge construction activities can cause soil disturbances that introduce sediments into a receiving stream and potentially impact its quality and the ecosystem. The impacts of bridge construction activities are studied ...
RAINFALL-INDUCED SLOPE FAILURE – AN EARLY WARNING SYSTEM
(2021-12-16)
Globally, slope failures cause substantial death tolls and economic loss. Embankments constructed on high plasticity clay are vulnerable to cyclic swelling and shrinkage when subjected to climate. Thus, over time, soil ...
Evaluation of Geotechnical Parameters of Soil Using Electrical Resistivity Imaging
(2021-12-20)
Electric resistivity imaging (ERI) is an effective non-destructive and rapid measuring way of obtaining continuous soil subsurface resistivity profiles. An ERI technique can be used to identify moisture variations and soil ...
CARBON FOOTPRINT ASSESSMENT AND EMISSIONS REDUCTION STRATEGIES FOR THE UNIVERSITY OF TEXAS AT ARLINGTON
(2021-12-21)
In the past decade, many universities have started to ascertain their emissions and benchmark their progress towards sustainability and climate control. The University of Texas at Arlington (UTA) is no exception in working ...
NUMERICAL SIMULATION OF ANCHOR GROUP EFFECTS ON CONCRETE BREAKOUT STRENGTH WITHIN STEEL FIBER REINFORCED CONCRETE
(2021-05-07)
This study aims to investigate numerically, the effect of anchor groups on concrete breakout strength using nonlinear finite element analysis. Steel headed studs were cast in place within concrete of different amounts of ...
EFFECT OF MODIFIED MOISTURE BARRIER IN MITIGATING PAVEMENT DISTRESSES DUE TO EXPANSIVE SUBGRADE
(2021-05-07)
Surficial distresses in roadways of Texas are very common due to presence of high plastic clayey soil in the subgrade. Increased sensitivity of high plastic clay towards seasonal moisture change results in repeated swelling ...
