Outline of Final Research Achievements |
Bedload sensor was developed, and the applicability was confirmed experimentally. The sensor was mechanically developed and countermeasure for internal pressure was conducted to keep measurements by submerged loadcell. Bedload discharge rate was calculated by weight measured by loadcell and the correlation in velocity between water on the bed and representative velocity of sediment layer. The relation in bedload rate between calculation and measurement was evaluated and the universal constants between them were obtained experimentally. LVP sensor, which was consisted from loadcell, pressure sensor and vibration sensor, was also developed through the knowledge of bedload sensor, and the sensor was for debris flow detections. The developed LVP sensor was confirmed for filed measurement usage.
