Texas
Floods Seen by MODIS (caption below images)
As
much as two feet of rain fell on southeastern Texas last week
flooding three major river systems along the Gulf of Mexico.
NASA's Moderate-Resolution Imaging Spectroradiometer (MODIS)
onboard the Terra satellite caught these images before and
after the early July rain.
The first image, acquired before the flood June 24, 2002,
by Moderate Resolution Imaging Spectroradiometer (MODIS) on
NASA's Terra satellite, rivers are barely discernible. The
second image, captured July 8, 2002 shows massive flooding
of three major river systems along the Gulf of Mexico.
Rivers
and standing water appear dark blue or black against the gold-colored
landscape. The southern most river is the Nueces River, with
its northern tributary, the Frio River. To its north is the
San Antonio River, and farther north is the Guadalupe River,
which was hit especially hard by the flooding. In this false-color
combination, soil and sediments appear reddish, which shows
how muddy the floodwaters were. Images courtesy Jacques Descloitres,
