Dam Integrity Monitoring

Dam Integrity Monitoring with SAR Interferometry (InSAR)

To prevent dam collapse and severe social and economic loses, effective dam monitoring strategy is required. Usually, collapses are caused by the infrastructure aging, changes in dam's foundation, structure, and water level. ICEYE's SAR satellite constellation enables frequent monitoring of a dam, regardless of clouds and daylight. With SAR Interferometry (InSAR), it is possible to monitor land subsidence regularly, this is especially useful to forecast and prevent possible dam collapses. 

ICEYE SAR satellite data is also helpful in responding to a dam collapse, with monitoring of the consequences. After the collapse, ICEYE data enables frequent monitoring of the region to update the damage extent necessary for safe and efficient search & rescue operations and mitigation efforts. 

ICEYE SAR SATELLITE DATA ENABLES:

• Frequent monitoring of the dam infrastructure.
• Monitoring of land subsidence with SAR Interferometry (down to millimetric accuracy).
• Early detection of anomalies, such as acceleration of land subsidence.
• Monitoring the impacts and aftermaths of a dam collapse. 

ICEYE continues to grow its current SAR satellite constellation capacity with the objective to provide daily interferometry and coherent change detection anywhere on Earth with a 24h ground track repeat. This breaks existing barriers in collecting SAR imagery stacks for InSAR analysis, bringing the collection time down with every new satellite in the ICEYE constellation. Since 2018, ICEYE has launched commercially available SAR satellites, and the company will continue to increase the size of the commercial constellation every year.
