When investigating the transformation of waves and hydraulic responses within physical and numerical models, it is crucial to replicate the natural conditions as accurately as possible. This often involves replicating extremely nonlinear irregular waves in areas with intermediate or shallow water depths. In doing so, special attention must be paid to the design of the model layout, which forms the central focus of the present work.
In short flumes, it is common to incorporate a steep transition slope before the actual bathymetry. Investigations are performed on how this transition slope influences wave parameters, and recommendations are provided for its appropriate use. In situations where it is not suitable, combining a numerical model with a physical wave flume is suggested. This study seeks to offer guidance for generating highly nonlinear waves in intermediate and shallow waters within a relatively short wave flume.
