Wave Set-up and Run-up Variability on a Complex Barred Beach During Highly Dissipative Storm Conditions

Abstract

ABSTRACT Nicolae Lerma, A; Pedreros, R. and Senechal N. 2016. Wave set-up and run-up variability on a complex barred beach during highly dissipative storm conditions. In: Vila-Concejo, A.; Bruce, E.; Kennedy, D.M., and McCarroll, R.J. (eds.), Proceedings of the 14th International Coastal Symposium (Sydney, Australia). Journal of Coastal Research, Special Issue, No. 75, pp. 882–886. Coconut Creek (Florida), ISSN 0749-0208. This study assessed the ability of the SWASH model to reproduce wave set-up and run-up on complex realistic 3D morphology during highly dissipative stormy conditions, based on the most energetic field data set reported in the bibliography (ECORS-Truc Vert'08 beach experiment). Several approaches (1D and 2D) and forcing methods (spectral and parametric) were applied. For the three days of high-energy conditions caused by the Johanna storm, wave set-up was accurately reproduced, with simulation performance in 1D and 2D at R2 = 0.66, 0.81 respectively for all data considered; RMSE = 0.13 m,...
