Title: | 3D Movable Bed Model Results Integration in a Shoreline Evolution Model |
Issue Date: | 2011 |
Abstract: | The critical analysis of the performance of a medium to long-term shoreline evolution model, which incorporates bottom change updating based on predefined rules, showed the need to improve processes description, namely beach profile development under the action of different wave conditions. The absence of coherent field data sets, particularly expensive for high energetic coastal zones as is the case for the Portuguese west coast, together with the possibility to access an experimental facility led to the completion of a three-dimensional movable bed model of a beach in a continued erosion situation. Furthermore, the effect of a transversal defense structure was also considered. The morphological time scale determination allowed the articulation between physical model results for profile development and simulations from the referred numerical model. The interpretation of these results, to what laboratory and scale effects were identified, may give some guidance for the numerical description of the profile development. |
