Karl E Winters


Karl is the acting National Flood Hazard Coordinator, and a Surface-Water Specialist in the Hydrologic Networks Branch, providing operational support and coordination of USGS flood response, as well as training and technical/operational support for flood documentation and modeling, and computation of streamflow records. Karl graduated from the University of Missouri - Rolla in 1991 with a B.S. in Civil Engineering. He started work for the USGS in the Mississippi District in January 1992 in the Flood Studies Section, performing 1-D and 2-D flow modeling, scour analyses, and numerous indirect measurements. From 2004 through 2013, Karl served as the Surface-Water Specialist for the Texas Water Science Center. Karl has conducted flood modeling and documentation surveys in several countries.  He instructs surface-water courses for Water Science Centers and at the National Training Center. Karl is an instrument-rated pilot and a registered professional engineer.
