[Outline of the Lecture]
This subject gives scientific contents on environmental hydraulics with several special seminars for obtaining basic knowledge of environmental management in hydrosphere, e.g., rivers, lakes, reservoirs and coastal seas. The minimum prerequisites are basic fluid mechanics and basic engineering hydraulics on steady flows. The lecture mainly focuses on water cycle and its dynamics in hydrosphere, heat and salinity transport through river basins, sediment and suspended solid dynamics, water quality change, and riverine ecosystem alterations. The special seminars design to deal with several management issues in real river basins for understanding relationships between the theories learned in the class and the real in situ problems.
[Key words]
environmental hydraulics, river basin management, basics of water and material transports, heat and salinity, sediment and water quality, and riverine ecosystems.
