Bridge scour monitoring using fixed instrumentation is a good way for the owner to be warned of imminent failure and to take appropriate action before exposing the public to undue risk. This paper demonstrates two cases of bridge scour monitoring systems developed for two bridges in Texas. The lessons learned from the two systems lead the authors to the conclusion that Tethered Buried Switches for early warning and tilt sensors for warning system should be preferred. Acceleration and frequency-based behavior tracked by motion sensors show promise but could only be demonstrated in laboratory experiments, with insufficient field data. © 2010 American Society of Civil Engineers.
