A waves, currents and sediment model is implemented in openTELEMAC to simulate morphodynamic changes on the East Coast of Florida, USA. This model produces temporal and spatially varying data for an external software to simulate the exposure and mobilization of UXO and DMM. The model retrieves its boundary conditions from global climate (ECMWF ERA-5 reanalysis) and ocean currents (HYCOM GoM regional analysis) models, thus providing a link between mesoscale dynamics and local conditions. Comparison between the model boundary forcings, model results and field measurements during the passage of Hurricane Matthew (October 2016) indicate that the model can simulate the hydrodynamics of the area. Comparisons with available LiDAR data also indicate that the model agrees with erosion and deposition patterns observed along the beach. Lastly, the model was run using conditions for an entire year, which produced a suitably long dataset for undertaking UXO and DMM mobilization studies.
