Abstract
A numerical model was used to simulate water levels, currents, waves, suspended sediment and salinity distributions in Pamlico Sound, a large and shallow back-barrier estuary in eastern North Carolina, for four distinct time slices during its geomorphic evolution over the late Holocene. Present-day bathymetry was obtained from a high resolution digital elevation model of Pamlico Sound, and paleobathymetric model grids were created for 500, 1000 and 4000 calibrated years before present (cal yr BP) using age-depth relationships developed from sediment core and time-constrained seismic observations. Hydrodynamic and sediment model results for a one-month simulation at the 0 and 4000 cal yr BP time slices are compared to assess the impacts of varying degrees of barrier island segmentation, long-term changes in basin geomorphology, and sea-level rise on the flow and transport response in Pamlico Sound.
