This figure shows the incremental change in mud area at the Chenier Plain from year to year (1991 - 1997).  Values above (below) the zero-line indicate accretion (erosion) from the previous year's measurement.  The red line indicates actual geomorphic measurements made from aerial photography.  The blue line indicates the modeled geomorphic estimates made using a combination of wind energy measurements and water level measurements from within Atchafalaya Bay.  Note the large amount of accretion from 1996 to 1997.  The photography from 1997 showed the largest mud flat at the Chenier Plain seen since measurements began a decade ago.
