Abstract: A monitoring system includes a reference station, a mobile station, a plurality of integrated sensing units, and a server. The reference station is configured to provide fixed reference coordinates to the server. The mobile station transmits multi-frequency electromagnetic wave signals to the integrated sensing units. Based on water depth and position information detected by sensors of the integrated sensing units in combination with information of electromagnetic wave signals as well as a propagation distance and time, displacement information of the integrated sensing units can be obtained. The data is transmitted to the mobile station, which further transmits the data to the server, to accomplish monitoring for the reservoir landslide water-level-fluctuation zone. Automated monitoring is achieved and the monitoring cycle covers the entire deformation and evolution phases of landslides.
