A Finite Volume Implementation of the Shallow Water Equations for Boussinesq Gravity Currents
(2012-07-16)
The shallow water equations (SWE) are a powerful tool for modeling the propagation of gravity currents (GC) because of their relative simplicity, computational efficiency and accuracy. Finite difference solutions, either ...
Mitigation of Alkali-Silica Reaction in the Bibb Graves Bridge
(2012-07-23)
The Bibb Graves Bridge in Wetumpka, AL has severe damage due to
alkali-silica reaction (ASR) in two of its reinforced concrete arches. A mitigation
procedure developed in the summer of 2010 by the FHWA, ALDOT, and ...
Dynamics of Saltwater Intrusion Processes in Saturated Porous Media Systems
(2012-08-14)
The overarching goal of this dissertation is to contribute towards a better understanding of the dynamics of saltwater intrusion and the associated transport processes in coastal groundwater systems. As a part of this ...
Time-Dependent Deformations of Concrete for Precast/Prestressed Bridge Components
(2012-08-16)
Self-consolidating concrete (SCC) is a material that has properties capable of improving the quality and durability of structures. However, much is still unknown about the hardened properties of this material, including ...
Incorporating El Niño Southern Oscillation (ENSO)-Induced Climate Variability for Long-Range Hydrologic Forecasting and Stream Water Quality Protection
(2012-08-02)
El Niño Southern Oscillation (ENSO) has been found to have a strong predictable effect on streamflow in different parts of the world. Since ENSO has potential relationship to seasonal and inter-annual variability in ...
Trip and Parking Generation for Student-Oriented Housing Developments
(2013-04-08)
While there are many different residential land uses in ITE’s Trip Generation Manual, there is no land use category related to housing for college and university students. These housing developments are located off-campus, ...
Performance Measures for Prioritizing Highway Safety Improvements Based on Predicted Crash Frequency and Severity
(2013-04-05)
The goal of this research was to develop highway performance measures that could be used to prioritize safety improvement projects by utilizing results from predicted crash frequency and crash severity for roadways the ...
Strength Assessment of Soil Cement
(2013-01-07)
Soil cement is a mixture of soil, portland cement and water that, once compacted and cured, forms a strong and durable pavement base. Construction practices and variance among core strength data have led to questions ...
Application of Shrinkage and Swelling Factors on State Highway Construction
(2013-04-16)
The objectives of the research were to review the state of practice for roadway related earthwork calculations for the southeastern states, develop a calculation tool for comparing various state earthwork methods, demonstrate ...
