Irrigation Dam Monitoring

Quick Facts
- Add facts in ACF “Quick Facts”.
Challenge
Continuously monitor the dam’s structural integrity under seismic activity, water-level changes, and long-term aging, ensuring early detection of anomalies to protect downstream communities and remain compliant with regulatory frameworks.
Solution
The installation was implemented using the xDAS Sentry system, consisting of:
- 5 xWave triaxial accelerometers to capture vibrations and dynamic response of the dam.
- 1 xAlarm device for immediate alerts and reporting in case of seismic activity.
- xPlorer Premium with Voyager software as the central acquisition and processing module.
- Observer Data Analysis Suite for advanced post-processing and extraction of modal properties.
In 2024, the system was upgraded with 2 xInc inclinometer units, adding 4 channels of tilt and settlement monitoring to expand coverage of the dam body.
Outcomes
The system provides dam operators with real-time monitoring, automatic alarming, and detailed structural analysis. It enhances preparedness for seismic events, supports regulatory compliance, and strengthens long-term dam safety management. The 2024 upgrade further broadened monitoring capabilities, enabling more precise detection, assessment, and response to structural changes over time.
