This report describes the development,
application, and evaluation of two methods for
estimating the magnitude and frequency of floods at
ungaged, unregulated, rural basins in North
Carolina-( 1) the regional regression method and
(2) the region-of-influence method. A comparison of
these two methods, based on their predictive ability and
ease of application, also is presented. In order to
compare the two methods on an equal basis, each
method was applied to the same available data. The
regional regression and region-of-influence methods of
estimation were applied to the current data base of 317
sites with at least 10 years of unregulated peak-flow
record and evaluated.
