Scour is a major threat to the safety of bridges. Instruments for the measurement and monitoring of bridge scour are necessary to study scour processes and to support bridge management. The lack of robust and economical scour monitoring devices prevents the implementation of a bridge scour monitoring program among bridge owners. This project explores the design and analyses of scour sensors using principles of Time Domain Reflectometry (TDR). The performance of a scour probe was first tested in laboratory simulated scour experiments. Three different signal analyses methods were developed to obtain the scour depth from TDR signals. Besides scour depth, additional information related to scour assessment, i.e. sediment density and electrical conductivity of water, were also determined from TDR signals. The sensing principles and analysis algorithms were validated from simulated scour tests under various conditions which are expected to be encountered in the field. The field conditions considered included: variation of sediment types, water conductivity, turbidity, air entrapment, and water elevation. These further validated the robustness of the scour sensing principles. Upon validation, a field worthy sensor was designed. The sampling area and effective measured dielectric constant were determined using a finite element analysis method. Evaluation of the sensor indicated that it was able to successfully monitor the scour processes (scour and refill) in real-time with high accuracy. Six TDR bridge scour sensors were installed at BUT-122-0606 bridge on SR 122 over the Great Miami River in Butler County, with assistance of project partners GRL Engineers Inc., and J&L Laboratories. Automatic monitoring units were installed to automatically take scour sensor signals and wirelessly transmit the sensor data. The sensors were installed using routine geotechnical site investigation tools and procedures. High quality signals were obtained, from which the development of scour adjacent to bridge piers was measured. The results are reasonable. The pilot study points to the promise of this new technology for long term bridge scour monitoring purposes. Continued evaluation and refinement of this new scour monitoring sensor system is highly recommended.

Long span suspension bridges cost billions. In recent decades, structural health monitoring systems have been developed to measure the loading environment and responses of these bridges in order to assess serviceability and safety while tracking the symptoms of operational incidents and potential damage. This helps ensure the bridge functions prope

Flooding and scour can be major threats to the integrity of bridges. During flood events, scour at bridge piers and abutments can undermine the foundations of the bridge, causing significant damage or even total structure loss. Because scour occurs below the water level during a large flood event, it can be difficult to detect and may go unnoticed unless a targeted inspection is performed. The Kansas Department of Transportation (KDOT) is required by federal mandate to establish and maintain a bridge scour plan of action for all scour-critical bridges in the state. A plan of action can include the implementation of scour countermeasures to protect and stabilize a bridge and/or scour monitoring. Bridge scour monitoring presents multiple challenges for bridge owners, including state Departments of Transportation (DOTs). This research project surveyed in situ and ex situ monitoring options with particular attention on warning system options in the public domain. In situ monitoring can include portable and/or fixed devices for detecting bridge scour. Ex situ monitoring implies a statewide system that issues scour alerts to trigger bridge closures and/or inspections based on hydrologic conditions (rainfall and/or streamflow). A systematic statewide system would be preferable for monitoring scour-capable events at bridges across the state. KDOT could leverage existing United States Geological Survey (USGS) and National Weather Service (NWS) tools to monitor scour-critical bridges or pursue a vendor to offer a turn-key solution. For critical locations, additional measures could be implemented at specific sites to offer more information or a higher level of monitoring.
