Irrigation and Water Environment Engineering Lab
Machine-translated · View original
The lab studies how water is distributed to farmland and the water environments of rural areas.
AboutAbout the lab
Designing rich and beautiful water environments in rural areas
The Irrigation and Water Environment Engineering Lab conducts research to sustain water resources and water environments in agricultural and rural areas.
It studies agricultural irrigation and drainage systems, which deliver water to fields and carry away unneeded water, and develops methods for their rational design, operation and management, and low-labor maintenance.
The lab also aims to create a healthy water cycle and waterside environments by conserving water quality and ecosystems in rural areas.
Its research covers not only rural areas in Japan but also river basins in Laos.
Key terms
- Agricultural irrigation and drainage system
- The entire system of irrigation canals, drainage channels, intake facilities, and so on that delivers water to fields and carries away unneeded water
- Nutrients
- Substances such as nitrogen and phosphorus that feed plants and algae. Too much of them in water degrades water quality
- ICT
- Information and communication technology. Technology that uses sensors and networks to monitor or control conditions from a remote location

ResearchResearch themes
The lab aims to build sustainable water resources and water environments in agricultural and rural areas. Its research rests on two pillars: the design, operation, and maintenance of agricultural irrigation and drainage systems, and the conservation of water quality and ecosystems in rural areas.
*Illustrative imageDesigning and Managing Agricultural Water Systems
The lab studies rational hydraulic design, operation and management, and low-labor maintenance of agricultural irrigation and drainage systems. It also investigates topics such as how urbanization affects the labor required to manage irrigation facilities.
*Illustrative imageProtecting Rural Water Quality and Wildlife
This research aims to create a healthy water cycle and waterside environments by conserving water quality and ecosystems in rural areas. In collaboration with other universities and institutions, the lab investigates nutrient budgets in river basins in Laos and birds that nest in paddy fields, among other topics.
*Illustrative imageIntroducing ICT to Water Management
This research quantifies how much water management labor and irrigation water use are reduced when ICT-based water management is introduced on large-scale rice farms. The lab is also considering how to place automatic water supply systems across finely divided paddy fields.
