Numerical Study of the Morphodynamic Beach Profile with Varying Wave Conditions and Beach Nourished Schemes
This paper establishes a numerical model of one-dimensional beach profile evolution at a laboratory scale with XBeach, whose ultimate objective is to study the beach profile changes after applying beach nourishment. The prediction data of the model and related physical models are compared and calibrated. The schemes under different wave conditions, sediment volumes, grain sizes, and replenishment methods are numerically simulated on this basis. Some interesting conclusions can be drawn from the schemes. The beach profile does not change regularly with the linear variation of the sediment volume. So, the larger nourished sediment volume of the beach is not the better. Moreover, the results show that the sediment grain size is inversely proportional to the erosion intensity. These provide essential support for beach restoration design, rationality, and stability, as well as for judging the feasibility of beach restoration projects.
