Effects of Impoundments on Selected Streamflow Characteristics
The objective of this investigation will be to assess the effects of impoundments on streamflow across the contiguous hydrologic regions in South Carolina, North Carolina, and Georgia as defined by Feaster and others (2014, 2009). Given the historic flooding in South Carolina in October 2015 following Hurricane Joaquin (Feaster and others, 2015) and in South Carolina and North Carolina in October 2016 following Hurricane Matthew (Weaver and others, 2016) and September 2018 following Hurricane Florence (Feaster and others, 2018), some of the regulated streamflow records will likely include some of the highest peak flows measured under regulated conditions. Along with assessing changes in flood-frequency characteristics due to regulation from the impoundments, other selected flow characteristics will be assessed to gain a more complete understanding of impacts from regulation throughout the streamflow regime. The investigation will leverage flood-frequency data from the ongoing rural flood-frequency project, which will allow for inclusion of streamflow data from regulated basins within the hydrologic regions in South Carolina that are contiguous with Georgia and North Carolina.
