A Scalable Variational Inequality-Based Formulation That Preserves Maximum Principles for Darcy Flow with Pressure-Dependent Viscosity
(2017-08)The overarching goal of this thesis is to present a robust and scalable finite element computational framework based on Variational inequalities (VI) which models nonlinear flow through heterogeneous and anisotropic porous ... -
Abrasion Prediction at Kayraktepe Sediment Bypass Tunnel in Turkey
(2018-12)Sediment accumulation in reservoirs is a challenging issue that concerns most of the reservoirs worldwide. Use of sediment bypass tunnels is one of the potential solutions to reduce sediments deposited in reservoirs. ... -
Accelerated Alkali-Silica Reaction and Corrosion of Reinforcing Steel in Concrete: Application on Dry Casks
(2016-08)The durability is one of the main reasons making concrete the most abundantly consumed material in the world after water. However, severe exposure conditions and improper or low quality mixture designs can cause physical ... -
Active and Passive Sensor Fusion for Terrestrial Hyperspectral Image Shadow Detection and Restoration
(2016-05)Acquisition of hyperspectral imagery (HSI) from cameras mounted on terrestrial platforms is a relatively recent development that enables spectral analysis of dominantly vertical structures such as geologic outcrops. Although ... -
Advanced SAR Interferometry Methods for Ground Displacement Estimation from Spaceborne and Airborne Platforms
(2016-05)Interferometric synthetic aperture radar (InSAR) is a powerful technique to monitor ground deformation phenomena, such as landslides, ground subsidence, seismological activities, and volcano dynamics. In this dissertation, ... -
Aggregation of Lead Phosphate Nanoparticles: Implications for Lead Immobilization in Soil and Pipes
(2017)Flint, Michigan (2014) and Washington D.C. (2001) found high levels of lead in their drinking water pipelines. Problem: Lead in pipes is corroding and contaminating the drinking water. Goal: To study the aggregation behavior ... -
An Automated and Remotely Operated Siphon System for Flood Control
(May 2018)The proposed siphon system aims to release water from a wetland before a heavy rainfall that is forecasted to produce flooding. The storage made available by the early release would provide water storage for the heavy ... -
An Evaluation of Image Correlation Techniques for Measuring Sand Dune Migration Rates from Remote Sensing Data
(2019-05)The surface migration rates of sand dunes both on Earth and on other planets provide important information about local and regional wind patterns. However, in situ data is often unavailable and remote sensing data must be ... -
AN EXPERIMENTAL STUDY ON REPAIR OF STEEL BRIDGE PILES USING GFRP CONCRETE-FILLED JACKET
(2014-12)Many bridges and structures in the United States that are supported on steel piles exhibit inadequate strength due to increasing load demand and aging due to corrosion The combination of increased load demand and reduction ... -
Application of Cupriavidus metallidurans and Ochrobactrum intermedium for Copper and Chromium Biosorption
(2013-05)Heavy metals at high concentrations are toxic to the environment and living organisms. The present study aims to investigate the best conditions for the removal of CuSO4.5H2O and KCrO4 by two bacterial species: Ochrobactrum ... -
Aqueous-Based Processes for Enhanced Dissolution and Displacement/Removal of NAPLs
(August 201)This dissertation addresses the aqueous-based processes associated with alcohol fuel releases and treatment of hydrocarbon impacted soils. It is comprised of two parts. In Part A, the effects of alcohols (methanol, ethanol, ... -
Aquifer Experiments for Characterizing NAPL Sources and Dissolved Plumes following Releases of Ethanol-Blended Fuels
(2020-05)This research investigated impacts of releases to the subsurface of ethanol-blended fuels. The overall purpose was to study the evolution of a dissolved plume and non-aqueous phase liquid (NAPL) that is formed/displaced ... -
Autogenic Processes on Supercritical Submarine Fans
(2015-05)Submarine fans are large landforms typically built on the continental slope and abyssal plain. They are a amalgamation of depositional lobes emplaced over time through avulsion cycles. These type of intermediate scale ... -
Bacteria and Virus Control by Electrochemical Coagulation and Microfiltration
(2014-05)Bench-scale experiments were performed to evaluate microorganism control by electrochemical coagulation and membrane microfiltration. Natural organic matter (NOM) present in natural waters appears to reduce the effectiveness ... -
Bed and suspended sediments as source and transport mechanisms for polychlorinated biphenyls in the Houston Ship Channel Estuary System
(2012-08)Polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) are pollutants of global concern. Though their industrial histories differ, they both represent large classes of chemicals ... -
Behavior of FRP Strengthened Concrete Panel Elements Subjected to Pure Shear
(December 2)Several investigations have revealed that many aging civil engineering structures such as highway bridges are structurally deficient and need repairs and/or retrofitting. Among various solutions, fiber reinforce polymer ... -
