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 …
