Brief Abstract
Background
Monitoring dam deformation is essential for ensuring the safety and long-term performance of dam infrastructure. Conventional geotechnical instrumentation provides point-based measurements, while satellite-based Interferometric Synthetic Aperture Radar (InSAR) enables wide-area surface displacement monitoring.
Objective
his study aims to integrate instrumentation monitoring and InSAR observations with numerical modeling to improve deformation assessment of Saguling Dam.
Methodology
InSAR time-series analysis is used to detect and quantify surface displacement around the Saguling Dam area. The results are compared with available geotechnical instrumentation data to evaluate consistency and spatial deformation patterns. A numerical model is then developed to simulate the dam behavior and to support the interpretation of the observed deformation.
Key Contribution
The integration of remote sensing data, field instrumentation, and numerical modeling provides a more comprehensive framework for dam deformation monitoring. The approach is expected to support more effective monitoring strategies for large dam infrastructures.
