Bridge collapse due to scour and erosion
The In-situ Scour Evaluation Probe (ISEP)
"The In-situ Scour Evaluation Probe (ISEP) is the first technology that allows technicians in the field to measure the scour potential of soils without the need for excavation"
Erosion through water flow (called scour) causes the majority of bridge collapses in the U.S and was responsible for the levee failures in the aftermath of Hurricane Katrina. It has been difficult to assess the erosive potential of a soil profile without extensive digging on site followed up by hours of off site testing, but researchers at North Carolina State University (NCSU) have developed a device that significantly improves the process by measuring the scour and erosion potential of soils without the need to excavate and remotely test samples. Having tested the sensor in the lab the team are ready to conduct their first field tests.
