A. Study Area
The study area is a stretch of 230 km of levees along the
lower Mississippi River along the western boundary of the
state of Mississippi. At the time of image acquisition there was
one active landslide (latitude 32.5685, longitude -91.0393)
north of Vicksburg, Mississippi. A subset of 0.7 km length
containing this active landslide was chosen as the area of
analysis. The geo-referenced layers used in the analyses have
been masked by a 40 meter buffer from the crown of the levee
on the river side (where the landslides primarily occur). The
ground truth data was collected by the US Army Corp. of
Engineers (USACE) and the landslide polygons were drawn
using a GPS instrument during field data collection trips. This
data contains the location and timing of landslide appearance,
dimensions of the landslides, and their repair status.
