Modeling Shoreline Change And Resulting Wetland Response Due To Erosion And Sea-Level Rise: A Case Study In Dorchester County, Maryland, Mirtha Karinna Nunez
Modeling Shoreline Change And Resulting Wetland Response Due To Erosion And Sea-Level Rise: A Case Study In Dorchester County, Maryland, Mirtha Karinna Nunez
Dissertations, Theses, and Masters Projects
The present study was focused on developing a shoreline change forecast and wetland response model for Dorchester County, MD, to evaluate the vulnerability of wetlands to shoreline erosion and inundation due to relative sea level rise. The model considers the following forces involved in wetland stability and sustainability: inundation (as a function of topography and sea-level rise), shoreline erosion, vertical accretion and horizontal migration. To predict the long-term risk to nearshore wetlands and the potential habitat zone for wetlands in the next 50 years, shoreline change due to inundation and erosion/accretion was assessed within the frameworks of two-dimensional and three-dimensional …
Quantifying The Overwash Component Of Barrier Island Morphodynamics: Onslow Beach, Nc, Amy C. Foxgrover
Quantifying The Overwash Component Of Barrier Island Morphodynamics: Onslow Beach, Nc, Amy C. Foxgrover
Dissertations, Theses, and Masters Projects
A quantification of the role that barrier island overwash plays in the evolution of Onslow Beach, a barrier island located on Marine Corps Base Camp Lejeune, North Carolina, is presented. Ground-penetrating radar (GPR) and sediment vibracores provide an estimate of the relevant-sand prism above a silty/peat contact underlying the island. The average thickness from the surface, as determined from lidar, to this geologically-defined base, is less than 1 m and equates a total volume of approximately 1.8 ± 1.1 × 106 m3 over the 4.8 km stretch of Onslow Beach from 1 km north of the New River Inlet to …

Late Cenozoic Landforms, Stratigraphy And History Of Sea Level Oscillations Of Southeastern Virginia And Northeastern North Carolina, Pamela Crowson Peebles
Late Cenozoic Landforms, Stratigraphy And History Of Sea Level Oscillations Of Southeastern Virginia And Northeastern North Carolina, Pamela Crowson Peebles
Dissertations, Theses, and Masters Projects
A depositional model accounting for the stratigraphic sequences which accumulate during a marine transgression across a dissected coastal plain aids in understanding the geologic history of southeastern Virginia and northeastern North Carolina. Application of this model to the Shirley Formation (middle Pleistocene) and the Sedgefield and Lynnhaven members of the Tabb Formation (late Pleistocene) allows delineation of (1) the facies within, (2) the areal extent of, and (3) the landforms associated with these lithostratigraphic units. Facies within each lithostratigraphic unit consist of (1) a vertical succession from local, basal, channel-fill deposits and coarse, basal, lag deposits which grade upward into …
