Seasonal flooding in the lower Mississippi River Basin
Seasonal flooding is fairly common in the lower Mississippi River Basin in south central United States. Landsat satellite data are used by the U.S. Army Corps of Engineers and state officials to monitor the extent and the timing of periodic flooding.
In the March 2010 image rivers in the Basin (including portions of Arkansas, Missouri, Kentucky, Mississippi, and Tennessee) are at normal levels. The green tones along river lowlands mark marshy, grassy vegetation and water saturated soils.
In the 2011 image conditions have dramatically altered. The dark tones in the river regions represent expanded water bodies; the rivers have overflown their beds. In particular, the Mississippi River has swamped lowlands.
