Abstract :
The high resolution acquisition mode of TerraSAR-X provides a new dimension in fluvial landform change detection. Here we analyzed high resolution (5 m) coherence images with temporal baselines of up to a year from the Palpa Valley in the hyper-arid coastal desert of southern Peru. The results provide evidence that this sensor is suitable for mapping the land surface changes caused by erosion and sedimentation following rainfall and runoff events in bare desert landscape units.
