Abstract:

INDOT is considering the deployment of fixed scour-monitoring instrumentation in the field as part of a systematic response to the problem of scour around bridge piers and the associated FHWA mandates. A previous study had undertaken to investigate two types of scour monitors, one based on a sliding magnetic collar, the other based on a sonar. During two flow events however, the monitors suffered significant damage. This led to a re-design and modifications of how the sonar-based device was mounted to the pier. The latest configuration of the sonar mounting had been tested in the field for only a year before the end of the previous project, and this was insufficient to yield any definitive recommendations regarding its wider deployment. Similarly, a re-design of the means by which cables from the sliding magnetic collar were routed to the bridge-deck instrumentation box had been suggested but not investigated in depth. The present project therefore aimed at a more extensive testing of the sonar monitor, and an examination of the feasibility of a more robust cable routing for the sliding-collar monitor.
