Abstract

The present study offers a two-dimensional horizontal wave transformation model that can be applied on a general three-dimensional bathymetry of soft muddy coasts. The wave transformation model is based on time-dependent mild slope equations including the high energy dissipation of bottom mud layers as well as the combined effects of wave refraction, diffraction and breaking. The constitutive equations of visco-elastic-plastic model are adopted for rheological behavior of fluid mud. The results of the numerical model are compared with a series of the conducted wave-basin experiments. The performance of the application of the numerical model on a real field condition, i.e. Kumamoto Port of Japan, is also examined. Comparison between the simulated results and measured values in both laboratory and field conditions reveal the capability of the proposed wave transformation model to consider the wave attenuation on fluid mud layers.
