Figure 10-13. A combined radar and topography image of the Missouri River that experienced severe flooding and levee failure in 1993, acquired by the NASA/JPL (TOPSAR) system in 1994. The colors in the image represent elevations. The river's flood plain was completely inundated during the flood of 1993. Dark streaks and bands in the flood plain are agricultural areas that were severely damaged by levee failures. An outburst of water from a failed levee scoured a deep channel across the fields, which shows up as a purple band.
