What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

Pamlico Sound, a large back-barrier estuary in North Carolina, is under threat of climate change due to increased storm activity and sea-level rise. The response of this system is investigated by considering what has already happened during changes in sea-level over the late Holocene epoch. The hydrodynamic changes that occurred in response to geom...
Large estuaries are influenced by winds over adjacent coastal ocean and land areas causing significant spatial variations in water levels, currents and surface waves. In this study we apply a numerical model to simulate hydrodynamics and waves in the Albemarle-Pamlico Estuarine System, a large and shallow back-barrier basin in eastern North Carolin...
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 dig...

... A growing body of literature indicates that SLR induces variations to estuarine tidal structure, including tidal range, currents, and asymmetry, and thereby to water quality (e.g., salinity), eco-geomorphology, and associated feedback loops (Dessu et al., 2018;Khojasteh et al., 2023;Mulligan et al., 2019;Rayner et al., 2021). Understanding SLR-induced changes to the tidal range (i.e., the difference between high water and low water levels), is a useful proxy to learn about the response of estuarine processes to climate change (Haigh et al., 2020;Khojasteh et al., 2021b;Talke and Jay, 2020). ...
... North Core Banks separates the Atlantic Ocean from Core Sound, a southern extension of Pamlico Sound (Figure 1a). Pamlico Sound, Core Sound, and the Tar-Pamlico and Neuse River estuaries form a broad, shallow estuarine lagoon system that has negligible tides except near tidal inlets but is prone to wind-driven surges that have historically caused sound-side flooding (e.g., Cassalho et al., 2021;Clunies et al., 2017;Luettich et al., 2002;Mulligan et al., 2015;Peng et al., 2004;Pietrafesa et al., 1997). The ocean tides are microtidal, with a mean range of about 1 m (Hayes, 1979; NOAA Station 8656937) and a mean high-water elevation of ∼0.4 m NAVD88 (VDatum; Hess et al., 2005). ...
... The APES in NC (Figure 1) is the second largest estuarine system in the United States, and is a key part of the regional economy (Wells & Kim, 1989). Previous studies in this area have highlighted that the high variability in wind speed and direction during storm events can have dramatic effects on waves (Mulligan et al., 2015b), water levels (Clunies et al., 2017), productivity (Corbett, 2010;Giffin & Corbett, 2003), and morphology (Mulligan et al., 2015a;Paerl et al., 2006). Flooding in this low-lying area frequently occurs during storm events (Bales, 2003 Figure S1. ...
