Climate change brings about unprecedented increases in the occurrence of storms and flooding. In response to increased risk of bridge pier scouring, there is a need for increased safety monitoring of bridges. This paper presents a wireless sensor network (WSN) - based solution developed to measure micro-vibrations of a bridge pier. Test measurement values are converted with the use of the Fast Fourier Transform (FFT) method to obtain natural frequencies. Scouring depth of the pier is estimated with the use of a Finite Element Method model. WSN is used to collect the signal and to test data transmission stability in …
