| Abstract: |
The paper presents an innovative method to measure real-time scour depths around river bridge structures under both ordinary and flood conditions. The new approach adopts an array of temperature sensors based on optical fiber technology (Fiber Bragg Grating), located close to the immersed structure. Experimental laboratory tests are presented and results discussed, demonstrating the performance of the system in a variety of possible geometrical and flow conditions. Small-scale results are extremely encouraging with respect to the possibility of applying the technology to field cases. |
