Abstract
The North Georgia region experiences frequent instances of flash flooding due to the effects that urbanization have on precipitation enhancement. Historically, flash flooding has occurred within the metropolitan Atlanta area, and it is expected to increase as the climate continues to change. This research will focus on the use of stream gauge data provided by the United States Geological Survey to calculate the variable flashiness [ft3mi-2s-2]. Alongside the calculation of flashiness, the spatiotemporal distribution will be statistically tested to determine relationships between the magnitude of flashiness, the percentage of urban imperviousness, and the degree of hill slope at each stream gauge. The utilization of ArcGIS Pro will provide analysis techniques, as well as visualizations. Additionally, the seasonality of flashiness will be investigated to understand the periodic flash flood risk of this region.
