    Abstract

    Maintaining distributed levee systems has been an increased concern in the wake of natural disasters such as Hurricane Katrina and Superstorm Sandy. Ultimately, civil engineers strive to assess the health of these geotechnical systems; however, the variability of properties makes predictions of soil behavior extremely difficult, especially when soil models are not calibrated with field measurements. As climate change progresses in the form of continuous land subsidence and rising sea water level, weather-related extremes may also increase in their intensity and frequency. Coastal and waterfront zones are left especially susceptible. A remote sensing-based, i.e., satellite or airborne radar, health assessment of this spatially distributed system that can identify weak sections and impending failures can be a key to the sustainability of this infrastructure, helping prioritize maintenance and upgrade efforts. This paper presents the development of affordable sensing technologies, such as satellite-based interferometric synthetic aperture radar (InSAR), for use in a new health assessment framework to monitor and manage systems of a flood-control infrastructure. Historic and newly acquired TerraSAR-X StripMap data over a 1500 km2 footprint in New Orleans have been utilized to monitor ground settlements from February 2009 to February 2012. Local measurements from GPS and ShapeAccelArrays (SAAs) are integrated with the satellite-based InSAR measurements into a smart network to monitor the response of flood-control levees.
