How IoT Sensors Are Detecting Bridge Scour Before Collapse
Beneath the waterline, river currents erode the sediment around bridge piers—a phenomenon called scour that has caused more U.S. bridge collapses than all other causes combined. In this episode, Lucas and Luna explore how IoT sensors are now detecting scour in real time using accelerometers, tiltmeters, and water-pressure transducers. They focus on a specific case: the I-40 bridge over the Mississippi River near Memphis, where a retrofit sensor array installed in 2024 sends readings every 15 minutes to a cloud dashboard. The conversation digs into the physics of scour, the challenge of…
