Research Interests

alt text  


In the shallow coastal region, fluid flows may exhibit complicated behaviors strongly connected to physical effects such as turbulence, wave-structure interaction, wave-current interaction, wave breaking and fluid-density variations. Sometimes, complex hydrodynamic motions result in unexplainable events, for example, huge whirlpool inside harbor. As modeling of such complex phenomena requires dedicated considerations of the controlling physics, it is still recognized as important and so is popular topic in coastal and ocean engineering. Therefore, our research interests are basically towards a better understanding of coastal hydrodynamic processes which tend to be highly complex and turbulence-dominant due to a variety of physical factors, for example, irregular geometry, wave breaking, pycnocline, thermocline, flow-structure interactions and natural extreme events in the nearshore area. Our works typically expand into coastal hazards and environmental impacts which is directly linked to coastal hydrodynamics.
