Abstract
- Tsujimoto, G., Kakinoki, T., Hamaura Y., Shigematsu T. and Uno K., 2007. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 206 – 210. Gold Coast, Australia, ISSN 0749.0208 Sediment transport inside and outside a permeable submerged breakwater was examined in a laboratory experiment and a numerical calculation. The Macroscopic turbulence model, which has been applied for the thermal conduction in porous media, was used for the theoretical approach. A two- equation model for inside regions and 0- equation model was used for the outside region. Suspended sediment could be transported toward the onshore side due to two effects; vortex over sand ripples and the slope of a permeable breakwater. The amount of sediment deposited in the breakwater decreased gradually from the offshore to the onshore side during the experiment, while on the other hand decreasing rapidly in the numerical calculation. The surface profile over the submerged breakwaters could be reproduced excellently. [ABSTRACT FROM AUTHOR]
