Summary

The Three Gorges Project is the biggest hydrological project in the world. Due to the rapid change of water levels and various new constructions alongside the Three Gorges in recent years, landslides are expected to occur more frequently than before in this area. This requires a permanent surveillance of the area for risk monitoring. Slow moving landslides need to be monitored to understand their evolution procedure and assess the risk level, which is vital for minimizing the damages caused by landslides in the area.

Therefore, the proposed project has two main objectives:

  • Landslide monitoring in urban area using PS-InSAR with high-resolution TerraSAR-X image stacks.
  • Landslide monitoring in mountainous rural area with Partially Coherent Targets Analysis technique.

The proposed project is planned to last three years: from 2009 to 2012. This is in parallel to the ESA-MOST cooperative Dragon II project, which will provide additional remote sensing data from ESA satellites for cross-validation. At the same time, a pilot study named “Landslide deformation monitoring with SAR satellites” within the framework of the National Key Project “Geological disaster prevention and treatment in the Three Gorges reservoir area (phase III)” funded by the Ministry of Land and Resources of China is going on in the Three Gorges area, providing us with various ground-truth data for validation purposes.
