Billy E. Johnson, Ph.D., P.E., D.WRE, F.ASCE, a U.S. Army Corps of Engineers leader with over 30 years’ experience in water resources, has been named a Fellow by the ASCE Board of Direction.
Johnson works for the Engineer Research and Development Center in Vicksburg, MS. He is located in the Environmental Laboratory’s Water Quality and Contaminant Modeling Branch and is currently a remote employee stationed in Davis, CA. Within his duties at ERDC, he leads the Watershed WQ Modeling Group. He and his group are responsible for the development of the Training Range Environmental Evaluation and Characterization System and the Contaminant Simulation Module currently being applied at U.S. Army installations. They developed the Nutrient Simulation Module (NSM) for integration with multiple USACE Hydraulic and Hydrologic Models. These models are being used to solve complex water quality and ecosystem restoration problems in river systems such as the Missouri River Basin, the Columbia River Basin, and the Minnesota River Watershed.
As part of his research and development efforts for ecosystem restoration, Johnson is heading a team to develop the Riparian Vegetation Simulation Module. RVSM is being upgraded to include nutrient uptake and is being integrated with the Hydrologic Engineer Center River Analysis System (HEC-RAS-1D/2D) and the U.S. Bureau of Reclamation Sedimentation and River Hydraulics (SRH-1D/2D) modeling system. The integration of RVSM with these modeling systems will allow engineers and scientists to better model riparian vegetation growth, mortality, and nutrient uptake in an effort to better manage critical environmental resources.
In addition to his duties at ERDC, Johnson is an adjunct faculty member of the Civil and Environmental Engineering Department at Mississippi State University, where he has taught engineering hydrology and environmental hydrology. His students have gone on to work for government, university, and private consulting entities both within the United States and overseas. He is the group leader for the Surface Water and Watershed Water Quality Modeling working group within the Interagency Collaborative on Environmental Modeling and Monitoring. The goal of ICEMM is to foster information exchange and collaboration across government agencies working in the area of environmental modeling and monitoring. Through his efforts, multiple collaborative projects between federal agencies have been done which resulted in increased efficiency in developing modeling products for the user community and reduced duplication of effort between agencies.
He is a member of multiple technical societies and was one of the associate editors for Surface Water Hydrology for the Journal of the American Water Resources Association from 2007 to 2012.
Johnson received his B.S. in civil engineering from Mississippi State University (1987), his M.S. in civil engineering from Memphis State University (1993), and his Ph.D. in civil engineering from Colorado State University (1997).
