The scour is a critical factor of the bridge stability. Scour depths are usually determined using empirical formulas or numerical studies. But all methods always include uncertainties resulting from hydraulic and geology conditions, therefore it is necessary to measure scour depths by in-situ monitoring using a sonar. In this study, the new pro-filing scour monitoring system was developed for scour measurement in tidal environment and the performance of the new monitoring system was evaluated. Then, a case study was discussed.
