Obvious precursors to the slides and sand boils by sensing characteristics of the Moreover, it may be possible to detect less Sustainability of flood-control systems and to a more efficient and cost-effective A remote-sensing-based solution for rapidĭetection that can identify weak sections and impending failures may be the key to Prioritizing inspection and repair efforts. Early detection of occurrence of these events may assist levee managers in Slides (the main focus of this study) are the result of slope failure in the water-side of Two main events that lead to levee failures are slump slides and sand boils. To provide early warning of distress and degradation (e.g., Zeghal et al., 2013). Monitoring systems (e.g., Abdoun, et al., 2013) and multi-scale monitoring techniques Practice for levee monitoring including the development of large scale remote-sensingīased models (e.g., Aanstoos et al., 2012 Lv et al., 2013), real-time in situ Significant attempts have been made in the last few years to enhance the state of Greater knowledge about the status of levees would significantly improve theĪllocation of resources to inspect, and repair the ones with the highest risk of failure. Levees in New Orleans during hurricane Katrina and the floods in the Midwest andĪlong the Mississippi River are examples of this risk (Nakasone et al., 2010). In early 2007 the United States ArmyĬorps of Engineers (USACE) noted that nearly 150 levees in the United States poseĪn unacceptable risk of failing during a major flood (ASCE 2008). Failure of leveesĭue to man-made or natural hazards such as floods, hurricanes or earthquakes canĬause catastrophic damage and loss of life. There are more than 200,000 kilometers of levee structures with various designsĪnd conditions over the United States that provide flood protection. The results showed that over 70% of the false positives have similar soil Points are similar to the slide area, and if they can be vulnerable to future slump That of true positive points (i.e., actual slide areas) to understand if these false positive This studyįocuses on these false positive points by comparing their in-situ soil properties with Were some points, referred as “false positive points”, which were classified asĪnomaly by the classifier but no actual slide was found at those locations. While theĪutomated classification system correctly identified the location of actual slide, there River along the eastern side of the river in the state of Mississippi. The study area is focused on the mainline levee system of the Mississippi Provide information regarding soil texture, moistur e content and penetration In-situ data are collected via geotechnical field exploration to In addition to the remotely sensed data, extensive set of insitu soil data are collected to provide detailed information about the soils properties The PolSAR data are used as input in an automatedĬlassification system for characterizing areas in the levees facing anomalies with anĮmphasis on slump slides. In this study, aĭeveloped levee monitoring system using polarimetric synthetic aperture radar Identify internal weakness and vulnerable points at early stages.
