Abstract

In this study a modelling approach was investigated that takes into account the effect of short wave grouping on long wave motions, calculating sediment transport and morphology with multiple fractions and a layered bed stratigraphy. After extensive testing and validating this model using data collected in a wave flume in Hannover this model was used to simulate morphological development at nourished beaches. Based on the model results, an assessment on grain sorting effects during the development of nourished beaches was made, showing the models capabilities in functioning as a tool to predict sorting processes for natural and nourished beaches in a schematized environment.
