Our research interests include nonlinear wave theories, internal waves, sediment-laden flow, and turbulence in wave and current fields. We are particularly interested in the behavior of the Eulerian-mean flow change due to interaction between waves and a current.
- PIV measurements for rear-end and head-on collisions of solitary waves
- Mean velocity changes due to interaction between bichromatic waves and a current
- Changes in turbulent flow structure under combined wave-current motions
- PIV and PTV measurements of particle velocities and trajectories for Stokes waves following a steady current
- Partial standing waves due to a wave and current interaction and the amount of irregular-wave overtopping at a seawall
- PIV techniques for velocity fields of internal waves over a slowly varying bottom topography
- Particle image velocimetry measurements for Stokes progressive internal waves
- Shore protection to accelerative sea level rise and hypothetical tropical cyclone under El Nino weather pattern in small island states
- Floating cities as a solution to the escalating sea level rise in lower-lying land areas
- Study of saline water intrusion in Red River, Vietnam
- Study of water movement and quality in Ha Long Bay,Vietnam
