Sorption Of Nonpolar Organics On Minerals And Aquifer Materials, Thomas B. Stauffer
Sorption Of Nonpolar Organics On Minerals And Aquifer Materials, Thomas B. Stauffer
Dissertations, Theses, and Masters Projects
The sorption of nonpolar organic chemicals on hydrous oxides, clay minerals, and subsurface aquifer materials was studied using the batch isotherm technique. Radiolabeled (&\sp{lcub}14{rcub}&C) trichloroethylene, orthodichlorobenzene, naphthalene, and 1-methylnaphthalene were sorbed on mineral sorbents, subsurface aquifer materials, and a surface soil at six different equilibrium concentrations over a concentration range from 0.001 mg/L to 1.0 mg/L. A knowledge of the sorption coefficients of these fuel components and solvents is necessary to predict the transport of these chemicals through groundwater systems and ultimately to rivers, lakes, and estuaries. Sorption on oxides and surface soils was found to be pH-dependent with decreased …
Low-Energy Bedload Transport By Combined Wave And Current Flow On A Southern Mid-Atlantic Bight Shoreface, Malcolm O. Green
Low-Energy Bedload Transport By Combined Wave And Current Flow On A Southern Mid-Atlantic Bight Shoreface, Malcolm O. Green
Dissertations, Theses, and Masters Projects
The control of the mean flow, wind-wave energy and wind-wave asymmetry on low-energy bedload transport magnitude, direction and divergence on a wave-dominated shoreface was investigated. The objective was to develop a mechanistic basis for postulated fairweather replenishment of the beach sediment prism by sediments derived from offshore. Fairweather currents were measured at 17.5-m and 22-m depth. Periods of competent flow were identified using a combined-flow boundary-layer model. Madsen and Grant's (1976) combined-flow bedload-transport model was used to calculate sediment fluxes after modification of the expression for instantaneous transport rate to include a threshold criterion; this was necessary since sediment is …
Occurrence And Distribution Of Shell In The Vicinity Of Parker's Rock, Pocomoke Sound, Carl H. Hobbs Iii
Occurrence And Distribution Of Shell In The Vicinity Of Parker's Rock, Pocomoke Sound, Carl H. Hobbs Iii
Reports
This is a summary report on the investigation of the occurrence and distribution of shell in the vicinity of Parker's Rock. Pocomoke Sound. The investigation was performed by the Virginia Institute of Marine Science at the request and with the financial support of the Virginia Marine Resources Commission. The site (Figure 1) was selected. primarily. at the direction of the Commission. acting on the recommendation of its shell-dredging contractor and. secondarily. with supporting reconnaissance seismic data from VIMS.
