| Outline of Final Research Achievements |
It needs data of water level and discharge of past flood to decide a river disaster prevention plan. But these hydrological data is not measured at many rivers of small and medium sizes. Because the amount of budget and headcount of engineer for river management is not enough to make observation to obtain the hydrological data. So, new method that can measure a flood cheaply and easily is required. It knows that a plant shows stress response if a plant is given external physical force. For this reason, it is assumed that molecular biological information of a plant growing in a river channel have physical information of past flood like velocity, discharge and so on. This study clarified what kind of stress response occur by external force that is caused by the open channel flow. And this study could show that the possibilities to be able to use plant as a sensor to measure flood velocity, discharge by analysis of molecular biological data of plant.

| Academic Significance and Societal Importance of the Research Achievements |
気候変動で高まる豪雨ポテンシャルに対応できる河川整備が求められる中で基礎データとなる流量や水位が観測されていない小中規模河川が多数存在する．本研究で目指す技術はこのような無観測河川の解消を実現する．これが本研究の社会的意義である．
また，本研究は従前とは全く異なる生育・分子生物学的情報を用いた計測原理に基づく河川洪水流の流れを計測する植物センサーを開発するものであり，制御工学理論を媒体として過去に全く例のない河川水工学と植物分子生物学の融合という新たな学問分野の開拓によってこれを実現するものである．この技術は従前の物理原理に基づく河川モニタリングの限界にブレークスルーをもたらす可能性を持つ．
