Abstract:The central purpose of this report is to present methods
for estimating the magnitude and frequency of floods on
urban and small, rural streams in the Southeast United States
with particular focus on Georgia, South Carolina, and North
Carolina. Consequently, in this report the use of the term
“Southeast” refers specifically to Georgia, South Carolina,
and North Carolina. The analytical techniques described in
the report incorporate both urban and rural streamgages and,
therefore, can be applied to urban and small, rural streams. In
the Southeast rural flood-frequency investigation by Gotvald
and others (2009), Weaver and others (2009), and Feaster
and others (2009), the lower limit of drainage area for the
rural basins included was 1 square mile (mi2
). The lower
limit of drainage area for rural basins included in the current
investigation is 0.1 mi2
. Consequently, in this report, small,
rural streams refer to those with drainage areas less than 1 mi2
.
In addition, the scope of the investigation does not include
the Blue Ridge region due to an insufficient number of urban
streamgages.
