Abstract |
Many kind of sensors in the dam produce a lot of data associated with the maintenance and safety of the dam. So it is important to measure the reliability of the sensor (or measured data). In this paper, the new method using modified coherence function is proposed to measure the reliability of the sensor remotely. To verify feasibility of proposed method in the field, proposed method was applied to data of piezometer and earth pressure cell. Through field applications, the potential of the proposed method was verified.
