Field Implementation and Evaluation of the Simple Cost-Effective Scour Sensor

The work plan will include the following tasks: Task 1. Instrumentation system design and development of sensor multiplexing strategies, data acquisition, and data transfer activities. A meeting with IDOT-TRP will be arranged to finalize the plans. Task 2. Purchase of the fiber optic interrogation instrument, sensor multiplexer, dedicated computer and interface software Task 3. Operational software design, calibration inputs and development of automated data acquisition and data transfer system Task 4. Machining and fabrication of sensor rods, and installation of the fiber optic sensors within the sensor rods. It is planned to fabricate 10 to 16 sensors for a three span bridge. Task 5. Dry runs in the laboratory to fine tune the sensor/software interaction and the data acquisition and transfer process. This experiments will be simulated for the sake of software optimization and do not require submergence of the sensors in the water Task 6. Meeting with IDOT personnel to identify the bridge, establish installation plans, request for installation assistance, and possibly coordinate with USGS for use of their instrumentation box Task 7. Installation of the sensors, instrumentation, and interface software at the multi-span bridge site with several piers. Task 8. Field tests by simultaneous monitoring of several scour sensors. Evaluate scour depth detection capability, numerical calibration scheme and data acquisition and processing of the system. Task 9. Demonstration of the system to IDOT-TRP Task 10. Final Report documenting the system design, installation procedures, scour monitoring results, and software operations for IDOT's use.
