Charles Stillwell, Ph.D.
(he/him)Charlie Stillwell is a Hydrologist for the South Atlantic Water Science Center’s Watershed and Statistical Hydrology Team.
I study hydrology in altered watersheds, particularly those impacted by urbanization. How does development affect flow and water quality? Can green infrastructure counteract hydrologic alteration? I use statistical, data-driven methods to understand these patterns. My research supports water resource decision makers and I hope that my work promotes environmental justice whenever possible.
Science and Products
Raleigh Bank Erosion Project
The City of Raleigh partnered with the U.S. Geological Survey (USGS) to assist in assessing streambank erosion hotspots along the City of Raleigh’s stream network to support the City’s efforts of prioritizing future stream mitigation projects. Streambank erosion potential will be assessed using remotely sensed light detection and ranging (lidar) data, field assessments of streambank conditions...
North Carolina Sustainable Rivers Program
In 2002, The Nature Conservancy and the U.S. Army Corps of Engineers launched a collaborative effort to find more sustainable ways to manage river infrastructure to maximize benefits for people and nature. As of 2021, the Sustainable Rivers Program study area includes 40 rivers, 89 reservoirs, and 10,953 downstream river miles. The USGS South Atlantic Water Science Center and USGS Wetland and...
Ft. Gordon, Georgia, Stormwater Assessment
Fort Gordon is a U.S. Department of the Army facility located in east-central Georgia, approximately 10 miles west of Augusta, Georgia). The U.S. Geological Survey (USGS) South Atlantic Water Science Center is working cooperatively with the U.S. Department of the Army Environmental and Natural Resources Management Office of the U.S. Army Signal Center and Fort Gordon to assess the quality of...
Understanding the Effects of Stormwater Management Practices on Water Quality and Flow
Urban development can have detrimental impacts on streams including altering hydrology, increasing nutrient, sediment, and pollutant loadings, and degrading biological integrity. Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants. This project focuses on...
Monitoring water-quality and geomorphology in the French Broad River during I-26 construction
The North Carolina Department of Transportation (NCDOT) has partnered with the U.S. Geological Survey (USGS) to assess the water-quality and geomorphologic impacts resulting from the I-26 construction projects in western North Carolina. Streamflow, precipitation, and water-quality monitoring data, coupled with periodic assessments of geomorphology, will support the NCDOT construction-site...
Urban Waters Federal Partnership: Walnut Creek, Raleigh, North Carolina
The U.S. Geological Survey (USGS) South Atlantic Water Science Center (SAWSC) geographic area has two Urban Waters Federal Partnership (UWFP) watersheds: Proctor Creek in Atlanta, GA, and Walnut Creek in Raleigh, NC. The local efforts in Walnut Creek are supported by many partner organizations, including but not limited to: Partners for Environmental Justice, the Carolina Wetlands Association, the...
Water, Water Everywhere: Adapting Water Control Operations and Floodplain Conservation Planning to Global Change
Global change processes are producing shifts in temperature, precipitation, and seasonal streamflow regimes across North America. Much of the floodplain hydrology in the U.S. is managed through water control operations, often implemented on short time scales (e.g., weekly decisions), in response to short-term changes in precipitation. This operational model does not account for potential...
