Whereas near-surface causes of floodwall collapse (such as overtopping and undercutting) are directly visible and are well understood, the deeper causes of floodwall collapse (such as underseepage, overpressure, and small-scale variations in soil strength) are not predictable.
Building a 100% strong levee is impossible, but even the smallest failure is intolerable. Geotechnical studies are accurate, but prohibitively expensive. We forsee a new approach to monitoring flood protection barriers. Predictive and Proactive. Not reactive.
- Emphasize quick, repeatable geophysical monitoring as a practical, long- term solution to isolate anomalous damage zones along floodwalls (levees)
- Establish the best monitoring geophysical models and techniques that will help PREDICT and IDENTIFY damaged areas
- Complement and strengthen current engineering practices
- Train young scientists in the use of geophysical exploration methods, as applied to the monitoring of flood protection levees
To this end, a joint coalition between the LSU Department of Geology and Geophysics and the UNO Departments of Earth and Environmental Sciences, Physics, and Mathematics has been created. Please take some time to look over our work, and let us know if you have any questions. Thank you!
