{{CSDMS meeting abstract template 2025
|CSDMS meeting abstract=Sea level rise and changes in storm climate will modify the intensity of cross-shore sediment transport 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. In addition, shoreline change related to sea level rise and overwash deposition could vary alongshore in ways that could be dynamically coupled to patterns of coastline sculpting from gradients in alongshore sediment flux.

To examine how cross-shore and alongshore patterns interact, we will couple the BarrieR island and Inlet Environment (BRIE) model to the Coastline Evolution Model (CEM). BRIE has also been coupled to Barrier3D, which resolves cross-shore processes at higher resolutions. CEM was previously used to hindcast the component of coastline change patterns arising from alongshore sediment flux gradients, without including the components related to inlets or overwash. Coupled model experiments using BRIE, Barrier3D and CEM exploring how contrasting sets of processes dynamically interact will inform upcoming work to improve long term hindcasting and forecasting of shoreline change on complex coastlines.

|CSDMS meeting abstract=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.

|CSDMS meeting abstract=Sea level rise and changes in storm climate will modify the intensity of cross-shore sedimentary processes in the coming decades and centuries. Among the most significant of 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) predictions of changes in shoreline positions may be affected by the changes in sediment routing due to the presence of inlets.

To address this, we assess the suitability of presently available implementations of the BarrieR island and Inlet Environment (BRIE) model, which incorporates the Coastal Evolution Model (CEM) of alongshore transport, for long-term shoreline change modeling which was previously conducted using an implementation of CEM without inlets. BRIE has been implemented in Python for compatibility with the CSDMS BMI and also coupled to Barrier3D which resolves cross-shore processes at higher resolutions. However, these methods may be computationally expensive or otherwise inappropriate for running long term models of large scale domains as was previously done for the entire Carolina coast since 1870.

Alternatively, the methods unique to BRIE can be coupled with existing implementations of CEM that can handle complex coastlines. This may require alternate applications of alongshore transport forcings with inlet-related forcings, potentially incurring other computational costs or additional simplifying assumptions. We will ultimately pursue an implementation with the most accurate results and reasonable completion times for benchmark model runs.
