Abstract:

Flood frequency analyses for the Black Hills area have especially large uncertainties and are especially important for planning purposes because of a history of extremely large and damaging floods, such as the extreme floods of June 9 10, 1972. Geology, topography, and climatology are additional complicating factors for flood frequency characterization for the area. Two previous paleoflood studies for the Black Hills area indicated good potential for improving flood frequency analyses through implementation of paleoflood investigations. The objectives of this study (SD2010 04) for the southern Black Hills were to (1) develop long term flood chronologies and associated peak flow frequency analyses for selected stream reaches by applying paleoflood hydrology approaches; and (2) develop flood frequency information regarding “high elevation” stream reaches to help address questions regarding differential potential for generation of exceptionally strong rain producing thunderstorms across elevation gradients in the area. Neither objective was accomplished because the study was terminated before planned completion.
