Abstract:

This study aims to integrate commercial measurement and communication components into a scour

monitoring system with magnets or electronics embedded in smart rocks, and evaluate and improve its

performance in laboratory and field conditions for the movement of smart rocks. Properly-designed

smart rocks were found to be automatically rolled into the very bottom of a scour hole and can give

critical information about the maximum scour depth and effectiveness of rip-rap mitigation strategies.

Four types of smart rock technologies were investigated in this proof-of-concept phase of study,

including passive with embedded magnets, active with magneto-inductive communication, active with

controllable magnet rotation, and active with acoustic communication. Their performances were

evaluated against three criteria: 1) movement accuracy within 0.5 m, 2) transmission distance between

5 and 30 m, and 3) at least one measurement every 15 minutes. Test results demonstrated that the

proposed smart rocks are cost-effective, viable technologies for bridge scour monitoring.
