Abstract

In coastal and estuarine environments, sand-mud mixtures are often formed due to supply of various types of sediment discharge from rivers. For better prediction of the sediment transport patterns and the resultant bathymetry changes in these areas, it is important to apply a sediment transport model that can represent the behavior of sand-mud mixtures depending on the mud content to the simulation. This study aims at elucidating the effect of the mud content on the erosion processes of sand-mud mixtures under the combined wave and current forces through a field observation and flume experiments. A sand-mud mixture transport model was validated based on the field and experimental results.
