Mechanics Of Beach Cusp Formation, Asbury H. Sallenger
Mechanics Of Beach Cusp Formation, Asbury H. Sallenger
Dissertations, Theses, and Masters Projects
Beach cusps are crescentic shoreline accumulations of unconsolidated sediment that are characterized by a quasi-equal longshore spacing. The processes controlling the development of the cuspate form and the spacing of cusps were investigated. Field measurements showed that the cuspate form was derived through erosion of beach ridges, The ridges oriented alongshore in the swash zone are characterized by quasi-equally spaced channels cut normal to the shoreline whose widths are much less than the channel spacing. The upwash flows up the front face of the ridge and ponds shoreward of the ridge crest. The ponded fluid returns seaward through the channels. …
Carbon Transport In Two York River, Virginia Tidal Marshes, Kenneth Alan Moore
Carbon Transport In Two York River, Virginia Tidal Marshes, Kenneth Alan Moore
Dissertations, Theses, and Masters Projects
Annual net transports of particulate organic carbon (POC), dissolved organic carbon (DOC), and ATP-carbon were determined for two York River, Virginia, tidal marshes by monthly sampling for one year. Annual net losses of POC, DOC, and ATP-carbon from the marsh to the York River were observed for both areas, indicating that the long-term effect of these marshlands is to contribute both living and detrital organic material to the estuary. The mesohaline marsh area, Carter Creek, was observed to have the greater amount of organic carbon loss in the particulate fraction, while the oligohaline marsh area, Ware Creek, was observed to …
Heavy Metal Concentrations In The Clam Rangia Cuneata From The Rappahannock And James Rivers, Robert Emile Croonenberghs
Heavy Metal Concentrations In The Clam Rangia Cuneata From The Rappahannock And James Rivers, Robert Emile Croonenberghs
Dissertations, Theses, and Masters Projects
This project investigated the feasibility of using the brackish water clam Rangia cuneata as a heavy metal pollution indicator, and further investigated the state of heavy metal pollution in the James River. Rangia cuneata were sampled in the fall of 1972 from the Rappahannock and James Rivers , and meats were analyzed by atomic absorption spectrophotometry for wet weight concentrations of copper, zinc, cadmium and lead. Levels of copper and zinc in Rangia cuneata were shown to be unaffected by clam size, spawning differences, salinity or distance upriver, and substrate grain size. Heavy metal concentrations in the oxidized channel sediments, …
Benthic Infaunal Community Formation In Dredged Areas In Hampton Roads, Virginia, Thomas Karl Duncan
Benthic Infaunal Community Formation In Dredged Areas In Hampton Roads, Virginia, Thomas Karl Duncan
Dissertations, Theses, and Masters Projects
The macrobenthic fauna in three dredged areas in Hampton Roads, Virginia was sampled for 14 months. Repopulation occurred very rapidly after the cessation of dredging, but the dominant species were generally not those previously recorded as mud-bottom dominants in the Hampton Roads area. The faunal changes through time somewhat agreed with those reported in classical successional sequences. This dissertation is from the Joint Program Degree from the College of William & Mary and University of Virginia and awarded by the University of Virginia.
