Abstract :
The potential of satellite repeat-pass SAR interferometry (InSAR) for flood monitoring is discussed. Using ESR-1 SAR images covering the 1993/94 flood event in the river Rhine, Germany, it is shown that, by evaluating the scene coherence, a reliable mapping of flood extent is feasible, even in cases of rough water surfaces where the analysis of conventional SAR intensity and multi-temporal images may fail
