Abstract
40 percent of the world's population is presently living in coastal areas. Taking into account that the vulnerability of these areas is increasing due to sea-level rise and coastal hazards, the importance of safety structures is increasing as well. Hence, a spatial distributed dike monitoring should be part of a sustainable adaptation strategy. Persistent Scattering Interferometry combined with the Small Baseline Subset technique will be a very suitable monitoring technique for dike structures to identify dike movement with the accuracy of few millimeters. In opposition to ground-measurements, the spatial coverage of this technique provides comparable results for different parts of the dike. This could prevent future dike crevasses and help to reduce risks in high-populated areas. This paper describes the potential of the combined StaMPS MTI technique for a spatial distributed dike monitoring at the North Sea coast in Germany. 21 ERS-2 scenes and 16 Envisat ASAR scenes were processed for two different types of dikes. On the first an adequate density of PS pixels was found to perform spatial distributed monitoring. Due to decorrelation effects of vegetation covered surfaces, no reliable statements about the dike body could be made on the second dike, still deformation processes could be detected.
