Studies of recent severe floods in the southeastern United States have raised concerns that more frequent and/or intense rainfall events in combination with expanding urban areas might lead to increased damages and expenditures in future decades. Our regional climate modeling experiment therefore examines the potential effects of combined urban land expansion and increasing greenhouse gas emissions on future warm season extreme rainfall events across Atlanta, Georgia. These simulated events are compared to the September 2009 Atlanta flood event that led to a Federal Disaster Declarations for 17 Georgia counties.
