| Outline of Final Research Achievements |
A large-eddy simulation (LES) study on tidally-induced internal waves and turbulent mixing processes over a marine bank (or an artificial mound reef) was conducted and the obtained results were used to examine the behavior of suspended particulate matters. After verifying the simulated results with the results from hydraulic model experiment, we carried out several numerical experiments to examine the effects of the existence of marine bank and sea water density stratification on the behavior of the suspended particulate matters. The simulated results demonstrated that the marine bank played important roles in the upward transport of particles from the near-bottom to the upper areas, especially under the stratified density conditions.
