Abstract

Despite sonar transducers provide low-cost and easy-to-use methods for real-time distance/depth measurements, its reliability in use for flood-induced bridge scour monitoring has not been secured due to intrinsic noises of the sonar sensors in turbid and turbulent water conditions. Three-step signal processing algorithm is proposed and experimentally verified to improve both static and dynamic sonar measurements in such turbid and turbulent conditions in this study. Feasibility of multi-scale use of different frequency sonar sensors has also been investigated.
