About Us

Our research uses empirical and mathematical methods to study water flows with immersed solid grains, and the geomorphic action they exert on river, lake, and sea beds. We conduct micro-scale experiments in our laboratory at National Taiwan University, and observations of field-scale processes at various locations in Taiwan. We also seek to model the corresponding behaviors by formulating and solving simplified mathematical equations.
