Process-Based Model Prediction of Coastal Dune Erosion through Parametric Calibration

Coastal dunes are important morphological features for both ecosystems and coastal hazard mitigation. Because understanding predicting dune erosion phenomena is very important, various numerical models have been developed to improve the accuracy. In present study, a process-based model (XBeachX) was tested calibrated accuracy of simulation from storm event by adjusting coefficients in comparing it with large-scale experimental data. The breaker slope coefficient predict cross-shore wave transformation more accurately. To prediction profile, related skewness asymmetry were adjusted. Moreover, bermslope performance near face. Model assessed based on model-data comparisons. XBeachX successfully predicted phenomena. addition, results obtained other two similar experiments same set matched well observed profile However, underwater sand bar evolution remains challenge.
