Non-Contact Scour Monitoring for Highway Bridges

This research proposes the use of laser ranging sensor with the signal wavelength in the green spectrum (Approx. 500 nm) of Electro Magnetic Radiation (EMR) for underwater scour monitoring. This includes developing methodologies to use green laser system on a static or mobile platforms like truck, boat, USV (Unmanned Surface Vehicles) and UAS (Unmanned Aerial Systems) to map the condition of bridge substructure submerged in the water. It is crucial to convert the derived depth information from these non-contact bathymetric sensors to meaningful scour conditions, which will be accomplished in this project through simulated lab-based and actual prototype field experiments.
