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 satellite SAR data enables frequent monitoring of a dam with accurate and immediate information on detected changes.  SAR Interferometry (InSAR) is a reliable tool for regular monitoring of land deformation, the advanced methods of which allow sub-millimetric accuracy in optimal conditions that is especially useful to forecast and prevent dam collapse. 

ICEYE radar satellite data is also helpful in near-immediate response to dam collapse, with monitoring of the consequences. After the collapse, ICEYE data enables monitoring of the region frequently to update the damage extent necessary for safe and efficient safe & rescue operations and mitigation efforts. 

ICEYE SATELLITE SAR DATA ENABLES:

• Frequent monitoring of the dam infrastructure
• Interferometry with down to millimetric accuracy for land deformation monitoring
• Early alarm on anomaly: e.g. acceleration of ground movements 
• Quick emergency response on dam collapse, assistance in mitigation measures 

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.
