Abstract

We applied the differential SAR-interferometry to detect subsidence in the brown coal mining area of the Lower Rhine Embayment, Germany. The displacement is caused by groundwater withdrawal. For this approach, 40 ERS-1/-2 scenes covering a time interval of about 4 years were processed. In a first evaluation, a mean displacement rate of about 50 mm/yr was observed. This estimation agrees very well to the leveling measurements. In addition, we applied the Permanent Scatterer techniques in order to get a detailed understanding by pointwise information beside the spatial data.
