Modeling of sedimentation processes in closed-end canals
Title
Modeling of sedimentation processes in closed-end canals.
Creator
Li, Lin, Florida Atlantic University, Scarlatos, Panagiotis (Pete) D., College of Engineering and Computer Science, Department of Ocean and Mechanical Engineering
Abstract/Description
Due to the fact that most of closed-end canals are protected from high energy inputs, these canals tend to act as sediment traps. Accumulation of deposited material creates navigational and flood problems. Shoaling in closed-end canals is caused mostly by fine sediments. The behavior of fine sediments can be quantitatively described by means of a mass balance equation. More specifically, the advection-dispersion equation including proper sink/source terms can be used. The sink/source terms...
Show moreDue to the fact that most of closed-end canals are protected from high energy inputs, these canals tend to act as sediment traps. Accumulation of deposited material creates navigational and flood problems. Shoaling in closed-end canals is caused mostly by fine sediments. The behavior of fine sediments can be quantitatively described by means of a mass balance equation. More specifically, the advection-dispersion equation including proper sink/source terms can be used. The sink/source terms represent the processes of deposition and erosion respectively. The purpose of this thesis is to develop analytical solutions of the unsteady advection-dispersion equation as applied to free surface closed-end canals. Solutions are obtained under various initial and boundary conditions, by using the finite transformation analysis. The simulation results are validated against laboratory data.

REDOX ENVIRONMENT CONTROLS ON THE DEGRADATION OF HARMFUL ORGANIC CONTAMINANTS IN MARINE SEDIMENT
Title
REDOX ENVIRONMENT CONTROLS ON THE DEGRADATION OF HARMFUL ORGANIC CONTAMINANTS IN MARINE SEDIMENT.
Creator
Quinan, Matthew P., Beckler, Jordon, Florida Atlantic University, Department of Marine Science and Oceanography, Charles E. Schmidt College of Science
Abstract/Description
Harmful organic contaminants, such as petroleum hydrocarbons, are ubiquitous in coastal marine ecosystems around the world, a problem that will only be exacerbated with rising sea level and increased inundation of coastal urban areas. Therefore, it is necessary to understand the fate of these contaminants following their deposition on marine sediment, where they can potentially persist for long periods of time. As organic carbon remineralization rates depend on the respiration process...
Show moreHarmful organic contaminants, such as petroleum hydrocarbons, are ubiquitous in coastal marine ecosystems around the world, a problem that will only be exacerbated with rising sea level and increased inundation of coastal urban areas. Therefore, it is necessary to understand the fate of these contaminants following their deposition on marine sediment, where they can potentially persist for long periods of time. As organic carbon remineralization rates depend on the respiration process employed by the bacteria in the sediment, it was the goal of this study to determine how the sediment redox environment, with an emphasis on Fe redox chemistry, affects the biodegradation of recalcitrant petroleum hydrocarbon compounds. While amendment of natural sediment with Fe minerals that are commonly transported to coastal areas following erosion from continental crust did successfully catalyze Fe reduction and inhibit sulfate reduction, the effect on the hydrocarbon biodegradation rate was negligible. However, inoculation of the sediment with Shewanella oneidensis, an exoelectrogenic, Fe reducing bacteria known to catalyze the degradation of hydrocarbon compounds found in crude oil, did significantly affect the redox environment and sediment microbial communities and alter the pattern of hydrocarbon loss in the sediment over time.

Sediment exchange in tidal inlets
Title
Sediment exchange in tidal inlets.
Creator
Merz, Clifford Ronald., Florida Atlantic University, Scarlatos, Panagiotis (Pete) D., College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description
Sediment exchange characteristics of tidal inlets subjected to tidal excitations are investigated and the results compared to field data measured at Jupiter Inlet, Florida. A specially written computer program combines inlet/nearshore hydrodynamic expressions with bed-load and suspended load sediment transport relationships to examine the building mechanisms of the near-shore tidal ebb shoal. The ebb tidal flow is modeled as a turbulent, plane jet which includes lateral mixing and entrainment...
Show moreSediment exchange characteristics of tidal inlets subjected to tidal excitations are investigated and the results compared to field data measured at Jupiter Inlet, Florida. A specially written computer program combines inlet/nearshore hydrodynamic expressions with bed-load and suspended load sediment transport relationships to examine the building mechanisms of the near-shore tidal ebb shoal. The ebb tidal flow is modeled as a turbulent, plane jet which includes lateral mixing and entrainment, bottom friction, and offshore bathymetric changes. Flood tidal flow is modeled as a potential flow sink with the water being drawn into the inlet from one or more dominant offshore areas depending on the offshore bottom slope. Sediment transport expressions are evaluated at various locations within the offshore flow field and the sediment deposition depth is calculated at that location over one tidal cycle. Model results are plotted and compared to field data for analysis.
