Floods in Georgia, magnitude and frequency: Techniques for estimating the magnitude and frequency of floods in Georgia with compilation of flood data through 1974

Techniques are presented for estimating the magnitude and frequency of floods having recurrence intervals of 2, 5, 10, 25, 50, and 100 years on streams with natural flow in Georgia. Multiple-regression analyses were used to define the relation between flood-discharge frequency for streams draining from 0.1 to 1,000 square miles and 10 climatological and physical basin characteristics. The analyses indicate that the drainage area of the basin is the most significant characteristic. Five regions having distinct flood-discharge frequency characteristics are delineated.
