河川構造物にかかる河川工学の課題

抄録

In the rivers a lot of structures are constructed and they play various functions; while they affects river flow, sediment transport, morphology and also the eco-system of rivers. Previously, our interests were on their functions and stabilities in active rivers, and we have attempted to plan, design and construct them optimally. In spite of recent advances in hydraulics and technology, many issues remain in planning, designing and construction and in order to solve them, research topics still remain for river engineering or hydraulics. In addition, environmental aspects such as eco-system preservation of rivers are current topics we have to tackle with.
