Floods in North Carolina, frequency and magnitude

Recorded annual flood stages and discharges at 144 gaging stations are listed.  Also included are maximum known flood stages and discharges, both at gaging stations and at miscellaneous sites.  Using the annual flood discharge at gaging stations a regional analysis of flood magnitudes and frequencies in the state was made.  Results of the analysis are (1) a composite annual flood frequency curve for North Carolina (2) two composite seasonal flood-frequency curves for the State, and (3) curves for transferring the composite frequency curves to specific sites on the basis of location and drainage area.  A summary shows the flood-frequency relationships, the method of determining flood frequency at a site, and the application of flood-frequency information to typical problems.
