Sea level rise and changes in storm climate will modify the intensity of cross-shore sedimentary processes in the coming decades and centuries. Chief among these processes is the opening of tidal inlets on barrier islands which can affect nearby erosion rates and shoreline positions on a decadal time scale. It is unknown how longer term (centennial to millennial) projections of shoreline-change patterns may be affected by sediment routing related to inlets.
To address this, we seek to apply the the BarrieR island and Inlet Environment (BRIE) model for long-term shoreline change to hindcasting which was previously conducted using the Coastline Evolution Model (CEM) without depicting inlets. BRIE has also been coupled to Barrier3D, which resolves cross-shore processes at higher resolutions. By coupling inlet opening and migration processes in BRIE and Barrier3D with CEM, we will explore how cross-shore and alongshore processes dynamically interact on complex coastlines with inlets. These results will inform upcoming work to improve long term hindcasting and forecasting of shoreline change on the complex shorelines.
