Enhanced Dam Safety: The Use of GNSS Technology in Deformation Monitoring
The Use of GNSS Technology in Deformation Monitoring
Dam safety is critical to protecting downstream communities, infrastructure, and the environment. Monitoring dam deformation is key to maintaining their structural integrity, helping to identify potential problems before they lead to major failures. Historically, monitoring has often relied on optical total stations. While effective, these stations have a number of shortcomings.
Recent advances in Global Navigation Satellite System (GNSS) technology, such as the CHCNAV H3 GNSS receiver, are transforming the dam structural health monitoring approach. This technology provides continuous, highly accurate measurements that give us a detailed picture of a dam's structural health, overcoming the limitations of traditional methods.
THE ESSENTIAL NEED FOR PRECISE DAM DEFORMATION MONITORING
Uncovering the Forces Behind Dam Deformation
Dams face a number of natural and man-made forces that can weaken their structure over time. Water pressure, environmental changes, and seismic activity are key factors that can cause significant structural changes. Even small deformations can signal severe structural problems that threaten the dam's stability and, as a result, the safety of communities and ecosystems downstream. Early detection and response to these small displacements is critical and underscores the need for continuous and accurate deformation monitoring.
