  • Explore rivers and oceans !
  • Experiment, numerical analysis, fieldwork, etc.
  • Study at your own pace !


Professor / HOSOYAMADA Tokuzo, Associate Professor / INUKAI Naoyuki
The professors in this laboratory respect the personal independence, support our research activites and encourage our job hunting. Prof.Hosoyamada has a hidden aspect, such as playing guitars and Prof. Inukai has a fun for car diving.

Research Content

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.

PC to be used to calculation

A Day in the Lab

Our laboratory proceed to work in numerical calculation in PCP operation room, Laboratory Experiment room and Large Experiment building. We come to the laboratory at free time almost everyday because our laboratory doesn't have hours on duty like a "Core Time". Seminars will be held for each academic advisor.It not only research progress report, but also study session, which is an opportunity to actively incorporate new knowledge and technologies.

Circulation open Channel (We can research Flow Velocity or Back Water)

Thesis Subjects

  • (M)Hydraulic characteristics in flood control measures for small and medium-sized urban rivers
  • (M)Review of Offshore wind power generation arrangement position for Murakami City and Tainai City
  • (M)The effect for downstream rivers due to the release of the dam
