TECHNIQUE FOR ESTIMATING MAGNITUDE AND FREQUENCY OF FLOODS IN VIRGINIA
Information is presented for estimating the magnitude and frequency of floods on natural streams in Virginia. Flood-frequency characteristics are defined for 299 gaging stations in Virginia having 10 or more years of record not significantly affected by man-made changes. The frequency characteristics were related to basin characteristics by multiple regression techniques and the equations derived can be used to estimate the magnitude of future floods with recurrence intervals as much as 100 years on ungaged streams if drainage area and slope for the site is known. At or near gaged sites, a weighted average of the regression results and the gaging station data is recommended. /FHWA/
