Automated Monitoring Project for Debris Flow Hazard Sites in Nyingchi, Tibet
Project Background
Nyingchi City in Tibet is located in the lower reaches of the Yarlung Tsangpo River. With well-developed glaciers, towering mountains, deep valleys, and highly variable weather, it is one of the regions most severely affected by debris‑flow hazards. In May 2022, in order to further advance the research and development of geological‑disaster monitoring and early‑warning equipment and to conduct pilot demonstrations of cutting-edge technologies—thereby enhancing disaster‑prevention capabilities—the Geological Disaster Technical Guidance Center of the Ministry of Natural Resources, in accordance with the arrangements and deployment of the Ministry and the China Geological Survey, organized the 2022 field‑trial program.
As the leading entity, SPEPC, together with Guilin University of Technology and Nanjing Zhongwang Satellite Communication Co., Ltd., jointly applied for a pilot project and successfully passed the expert review. It is responsible for constructing automated monitoring stations at three debris-flow hazard sites in Chawalong Township, Nyingchi City, Tibet, thereby validating the suitability of universal‑type monitoring equipment in extreme conditions characterized by frigid temperatures, high altitude, and no public network coverage.
Monitoring equipment
Deployed at each of the three debris-flow hazard sites:
Tipping-bucket rain gauge: Monitors rainfall intensity and cumulative precipitation in real time, and identifies rainfall thresholds that trigger debris flows.
Mud‑water level monitor (cable‑pull type): Installed within debris‑flow channels, it continuously monitors the fluid depth and water‑level fluctuations of debris flows, capturing the dynamics of debris‑flow movement.
Audio-visual alarm: Installed in downstream residential areas, it automatically triggers an audible and visual alarm when monitored data exceed preset thresholds, alerting residents to evacuate immediately.
Video surveillance equipment: assists in remotely monitoring on-site conditions, enabling visualized monitoring.
The equipment is powered by solar energy and battery storage, with data transmitted back via the BeiDou satellite communication system, effectively addressing the challenge of communication in remote areas lacking cellular coverage. All devices are designed to withstand low temperatures and resist electromagnetic interference, ensuring reliable operation in the extreme climatic conditions of high-altitude plateaus.
Implementation Effectiveness
The project successfully completed the construction and commissioning of automated monitoring stations at three debris-flow hazard sites in Chawalong Township, Nyingchi, Tibet. All equipment operated stably under extreme conditions—high altitude, frigid temperatures, and no public network coverage—demonstrating the reliability and applicability of Guilin SPEPC’s universal‑type monitoring devices in glacial plateau environments. The project’s outcomes have been recognized by the Geological Disaster Technical Guidance Center of the Ministry of Natural Resources, accumulating valuable experience for future automated debris-flow monitoring in plateau regions.
