Abstract :
This paper shows the monitoring system of dynamic state of river surface by using video image. The dynamic state is estimated by the flow speed and direction of micro blocks distinguished evenly on a frame of video. By the dynamic state of river surface, water behavior and dangerous area will be distinguished. Aim of this study is to clear the dangerous area, presume disasters, inform them to local/national government and alarm them to people.
