  • In order to monitor the river-bed scouring depth around Sutong bridge, a small-scale monitoring system was established with water piezometers to realize the real-time monitoring of the scouring depth in the middle area of pile-group foundation, and the sites of the water piezometers were optimized based on the network coverage model. A large-scale monitoring system of protected river-bed area was constructed using a multi-beam sounding system, and parts of monitoring data were analyzed. The result shows that the multi-scale monitoring system can monitored the scouring depth with high precision, and its monitoring precision can reach decimeter level.
