| Outline of Final Research Achievements |
Although real-time observation is required to manage properly natural rivers, convenience and reliable methods are still not established. The present study suggested an epoch-making automated system to measure the river flow velocity.
PID control could enable the boat-type robot to remain in position against the mainstream. This results in reasonable evaluation of the mean velocity by a rotation speed of the screw propeller. Reliable laboratory experiments with the prototype robot and electromagnetic velocimetry were conducted to obtain a calibration curve.We conducted not only in the laboratory flume but also in a natural river. The robot could move smoothly from the starting point near the operator’s site toward the target point where the velocity is measured, and it could evaluate the cross-sectional discharge. Further, developing PTZ camera system, we indicated possibility of use in 20-m width river.
