MUD TRANSPORT AND MUDDY BOTTOM DEFORMATION BY WAVES

Daoxian Shen, Masahiko Isobe, Akira Watanabe

Abstract


The present study focuses on numerical simulation of wave height decay and muddy bottom deformation under wave action. Experiments have been performed to determine the vertical distribution of the water content ratio of mud. Using the experimental results, a simulation model has been set up to estimate change in the water content ratio in the mud bed. Also, a simple one-dimensional numerical model has been developed to predict the muddy bottom deformation under waves as well as the wave height decay. Wave flume experiments have been carried out and the changes in the bottom topography and wave height have been compared with the calculations.
