Improving applicability of a parametric model for breakwater layout design

Abstract

During a previous research project, a parametric model for conceptual layout design has been developed. The model uses optimisation using genetic algorithms to approach the optimal breakwater layout for specific locations.
The developed model serves as a successful proof-of-concept. In the model, several aspects of design have been simplified. These simplifications result in limited applicability of the model. In this research, the proof-of-concept model is further developed to improve its applicability. To improve the applicability of the model, modifications and additions have been made regarding bathymetry, wave transformation, and sedimentation processes. The effect of these modifications and additions on the model results have been assessed. Thereafter, the updated model has been applied to a case study, to assess its performance when applied to a real port development project. Based on the assessments and the case study, conclusions have been drawn regarding the applicability and the performance of the updated model. The limitations and uncertainties of the updated model have been recognized and recommendations have been made concerning further research and model development.
