Livingston,
AL - April 25 - 28, 2003 |
|
Description
On April 25, 2003, heavy rains fell throughout
east-central Mississippi and west-central Alabama, causing extensive
and extreme flooding along the Sucarnoochee River. The
flooding was most apparent at Livingston, AL, which is near the
mouth of the Sucarnoochee River basin just upstream of the
confluence with the Alamuchee Creek.
Upwards of 5" of precipitation fell within the
Sucarnoochee River basin, with the highest amounts occurring in the
Ponta Creek basin to the west of Livingston, AL. As a result
of this, the worst flooding occurred along the Sucarnoochee River
downstream of it's confluence with the Ponta Creek. This can
most readily be seen by comparing the hydrographs at Porterville, MS
with Livingston, AL.
As a precurser to the flooding between April 25 -
28, 2003, heavy rains and flooding also occurred between April 7 -
13, 2003. The severity of the flooding between the two events
was similar at Livingston, AL.
These two events are interesting in that they
occurred in close temporal proximity to each other, and resulted in
similar flood peaks and responses. Forecasters were able to
see the reaction of the Sucarnoochee River at high water levels,
which aided in model calibration for future events. |
