Recent developments of experimental studies along with computational techniques lead to the comprehensive understanding of engineering phenomena 3.3 Physical Modelling. Designers use physical models to visualize information about the context that the model represents. It is very common for physical models of large objects to be scaled down and smaller objects scaled up for ease of visualization. The primary goal of physical modelling is to test aspects of a product against user. The facilities typically used for coastal physical modelling investigations include: 0.6 m wave flume. 1 m wave flume. 1.2 m wave flume. 3 m wave flume. Wave basin. All wave flumes and the wave basin can be operated with monochromatic or irregular waves, defined by spectral or time series wave parameters, or by a pre-recorded wave signal
