In our laboratory, our primary research focus is on agricultural water facilities such as pipelines, open channels, dams, and irrigation reservoirs, all of which are essential for supplying water to farmland. Aiming to support sustainable agriculture and create beautiful and safe rural environments, we take an engineering-based approach to establish rational methods for the design and construction of agricultural water facilities. In addition to engaging in practical research on disaster prevention and mitigation, as well as maintenance and management of these facilities, we are also actively exploring new research themes in this field.

Our research extends beyond laboratory work, encompassing field surveys to identify real-world issues. To address these challenges, we employ a variety of methods—including physical modeling and numerical analysis— to develop effective solutions. Many of our research projects are conducted in collaboration with national research institutes and private companies. One of the distinctive strengths of our laboratory is access to well-equipped experimental facilities, such as a centrifugal model testing device.

Our current research topics include the following:

⇨Irrigation Reservoirs
Development of new seismic reinforcement methods for embankments (e.g., cement-based soil improvement)
Design methodologies for embankment rehabilitation using impermeable sheets
Technologies for reusing reservoir sediment
Research on precast outlet conduits

⇨ Pipelines
Long-term behavior of plastic pipes (creep phenomenon)
Analysis and countermeasures for sudden pipeline failures
Research and development of ribbed polyethylene pipes in soft ground
Technologies for preventing pipeline flotation
Lightweight thrust restraint methods for pipeline bends

⇨ Other Topics
Structural designs of coastal dikes considering overflow
Studies on debris flow disasters
Liquefaction mitigation using geocells
