Over the entire US, there are over 150,000 km of dam and
levee structures of varying designs and conditions. Currently,
there are limited processes to monitor these structures and
predict potential risk to communities. One type of problem on
along earthen levees which can be a precursor to failure during
a high water event is the occurrence of slough (or slump)
slides. On-site inspection of levees is expensive and timeconsuming,
so there is a need to develop efficient techniques
based on remote sensing technologies to identify levees that are
more vulnerable to failure under flood loading. Synthetic
Aperture Radar (SAR) technology, due to its high spatial
resolution and potential soil penetration capability, is a good
choice to identify problem areas along the levee so that they
can be treated to avoid potentially catastrophic failure.
