Hydro- and morpho-dynamic modeling of breaking solitary waves over a fine sand beach. Part II: Numerical simulation

A comprehensive numerical model is developed to predict the transient wave propagation, sediment transport, morphological change, and the elastodynamic responses of seabed due to breaking solitary waves runup and drawdown over a sloping beach. The individual components of the numerical model are first validated against previous analytical, numerical, and experimental results. The validated numerical model is then used to simulate breaking solitary wave runup and drawdown over a fine sand beach, where the experimental results are presented in (Young et al. 2010b. Hydro- and morpho-dynamic modeling of breaking solitary waves over a fine sand beach. Part I: Experimental study). The strengths and weaknesses of the model are assessed through comparisons with the experimental data. Based on the results, sediment transport mechanisms and wave–seabed interactions in the nearshore region are discussed.
