Charles Stillwell, Ph.D.

I'm interested in urban hydrology. How effective is green stormwater infrastructure across spatial scales? How can cities minimize hydrologic alteration? What are realistic restoration targets for urban watersheds? An understanding of hydrologic functions in urban areas are needed to address other challenges such as flooding, poor water quality, and ecologic degradation.

Understanding the effects of stormwater management practices on water quality and flow

Monitoring and assessment of the French Broad River before, during, and after I-26 construction

  • In cooperation with NCDOT, we are developing a real-time notification system that will report water quality changes downstream of major construction points. The USGS and NCDOT are also conducting periodic geomorphologic surveys throughout construction to measure the effect of causeways on streambed form and bank erosion.
