The southeastern United States (US) is dominated by moist, maritime air masses, and thus generally has large amounts of rainfall and plentiful water resources. However, increasing population and infrastructure in this region can lead to increases in flooding potential due to more impervious surfaces and at the same time, increases water demand (Gangrade et al., 2020;Nagy et al., 2011;Seager et al., 2009). Further, climate in this region also can lead to flooding and drought conditions. Rainfall rates in the southeastern US have been increasing (Ban et al., 2015;Trenberth et al., 2003), compounding issues of flash flooding due to increases in impervious surfaces in cities. Concurrently, temperatures in this region have increased, particularly nighttime temperatures, since the 1980s (Meehl et al., 2015; USGRCP, 2018), increasing water demand, which add to the strain on water resources from increasing population. However, high and low extremes in streamflow are infrequent, making it difficult to
