ABOUT
ABOUT
The Water Wave and Environmental Fluid Mechanics Research Laboratory focuses primarily on water wave related research. Topics range from basic science research to practical applications: fundamental studies on the generation, propagation, transformation, breaking, and runup of water waves, geophysical studies on tsunamis, as well as practical studies on water wave interaction with the foundation of offshore wind turbines. Other more general environmental fluid mechanics topics are also of interest, such as water-mud interaction and the mechanics of landslides. To ensure thorough and comprehensive understanding of our research problems, we employ a wide variety of research methods, including physical experimentation, numerical modeling, and theoretical investigation.

Landslide-generated tsunamis have been an ongoing research topic of the lab since Summer 2019.
Our progress on the construction of the wave flume as of Summer 2020.
Beginning in Summer 2019, the primary objective of our lab was to build a 2D wave flume.
The seabed of Taiwan Strait is found to consist of thick layers of muddy sediments. To investigate their potential effects on the foundations of offshore wind turbines, the wave-mud-structure interaction must be studied. As a first step, we simulated a solitary wave passing through a vertical cylinder over a muddy patch of the seabed.
A novel semi-analytical approach was devised to calculate the probability distributions of the characteristics of a tsunami generated by an underwater landslide. This example is based on the 1998 Papua New Guinea tsunami, believed to have been caused by an underwater landslide.
Probable (99th percentile) maximum trough-to-crest wave height of the leading wave at the end of the landslide tsunami generation process.
We conducted a theoretical investigation on the tsunamis generated by different mechanisms. In this figure, we compare the analytical solutions for a landslide-generate tsunami with those for a pressure-induced storm surge (also known as meteotsunamis).
