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.
