In our Labratory, we put our efforts into hydraulic phenomena. For example, Flooding, Density current at river mouth, Sandbar, River flow in the field of river engineering and Tsunami, Rip current, Nearshore currents, Swash oscillation in the field of coastal engineering. Reserach methods are numerical simulation, laboratory experiments, field survey and mathematical theory. In recent years, the statistical model and machine learning model are used as well as physical model. We recommend this laboratory for those who are interested in Information processing technology as well as traditional research methods.
