The researches of the Water Environment Engineering stand fundamentally on Environmental Hydrology and Environmental Hydraulics that are related with the analysis, prediction and control of the water environment in agricultural areas.
Ongoing research topics are 1) Mathematical modeling for water flow and movement of environmental materials in estuaries and closed water bodies (Hydraulic model, Ecosystem model, Numerical simulation, DO, Nitrogen, Phosphorus), 2) Watershed management model for predicting occurrence, circulation and distribution of water and environmental materials (Hydrological model, Numerical simulation, GIS, Nitrogen, Phosphorus), 3) Pesticide dynamics model in paddy and upland fields and its scaling-up to watershed model (First order kinetics, Numerical simulation, GIS, environmental risk assessment), 4) Quantification of flood mitigation function and prediction of flood runoff in flat low-lying agricultural areas (Hydrological model, Numerical simulation, Drainage and inundation analysis), 5) Eco-technology for biodiversity conservation in rural areas (Mathematical model, Fish preference, Agricultural canal) and 6) Development of technology for water quality improvement (Eutrophication, Aeration).
The researches of the Water Environment Engineering are conducted by using the hydraulic experiments and the numerical simulations incorporated with the latest numerical technique such as Fuzzy Theory, Artificial Neural Network, Genetic Algorithm, Wavelet Transformation and the tools obtained in Chaos Engineering.
