英文摘要	During extreme storms, both wind-driven changes in water levels and intense precipitation can contribute to flooding. Particularly on low-lying coastal plains, storm-driven flooding can cover large areas, resulting in major damage. To investigate the roles of rainfall and storm surge on coastal flooding, a coupled flow-wave model (Delft3D-SWAN) that includes precipitation is used to simulate two major storm events. The modeling system is applied over a domain covering coastal North Carolina, USA, including the large Albemarle-Pamlico estuarine system, and a long and narrow back-barrier estuary (Currituck Sound [CS]) that experiences major water level variations is investigated in detail. A high-resolution (50 m) grid with eight vertical layers is used to simulate the conditions during Tropical Storm Hermine and Hurricane Matthew in 2016. Hindcasts (winds, pressure, and precipitation) from eight different atmospheric models are used as atmospheric input conditions, and the results are compared with detailed observations of surface waves, currents, and water levels from sensors mounted on five monitoring platforms in CS. Results show that major differences exist between wind fields producing variations coastal conditions. Precipitation directly on the water surface had a large effect on water levels and produced a larger inundated area. These results help to understand the important contributions of each physical process (precipitation, wind-driven surge, and waves) to circulation and water levels, and provide guidance on the impact of atmospheric forcing conditions on back-barrier environments during hurricanes. © 2020.
