    Abstract

    The failure of flood-control infrastructure, such as levees, due to a natural or manmade hazard can have significant repercussions, sometimes with dramatic and unanticipated consequences on human life, property, and the country's economy. Thus, the integrity of a levee is an important issue that needs to be checked frequently. This can be achieved by long-term monitoring of the subsidence of the levee to identify potential weak sections and prioritize maintenance efforts. This paper presents the use of affordable sensing technologies, such as satellite-based interferometric synthetic aperture radar (InSAR), to monitor the settlement of the New Orleans area. Data from TerraSAR-X, the German Space Agency's X-band satellite, was processed with the interferometric point target analysis technique in the gamma remote sensing software for widespread settlement monitoring. The time frame of the data is from 2009 to 2014. In situ measurements from GPS and extensometers are used to verify the remote sensing results, and a good agreement of displacement trends between the two methods was obtained. The favorable comparison increases confidence in the suitability of remote sensing techniques to monitor the long-term displacement of entire levee systems.
