Climatology Study and Flooding Analysis in Atlanta

The objective of this study was to characterize the climatology of extreme rainfall and flash flooding in Atlanta.  Nine urban watersheds in the Atlanta area were examined and found to exhibit a range of urban development and land-use characteristics. Flooding in Georgia is wide-ranging and impacts areas from the coastal regions to the mountains at various times of the year. The major differences in urban watersheds come from the volume of water available for runoff due to surface coverings reducing infiltration, and storm drainage collection systems increasing the flow and magnitude of flood peaks. The large number of small-scale events in the Atlanta Urban Zone relative to other areas is likely due to urbanization, or the population shift from rural
