Rate My Professor Denny Johnson

Dennis Johnson, known as Denny Johnson, is the George "Fritz" Blechschmidt '54 Professor of Environmental Science at Juniata College, where he chairs the Department of Environmental Science and Studies as well as the Department of Civil and Environmental Engineering. He holds a B.A. in Natural Science from Lock Haven University (1989), a B.S. in Civil Engineering from The Pennsylvania State University (1989), an M.S. in Civil Engineering from Penn State (1992), and a Ph.D. in Civil Engineering from Penn State (1995). Johnson joined Juniata in 1999 as Assistant Professor of Environmental Science with a joint appointment in Information Technology, was promoted to Associate Professor in 2003, and served as Director of the Technology Solutions Center starting in 2002. Prior roles include Assistant Professor in Civil and Environmental Engineering at Michigan Technological University (1997-1999), Research Hydrologist as a UCAR Visiting Scientist with the National Weather Service Office of Hydrology (1996-1997), Post-Doctoral Research Assistant at Penn State (1996), and Instructor/Ph.D. candidate at Penn State (1992-1995).

Johnson's research specializations encompass hydrologic and hydraulic modeling, watershed management, GIS applications, information technology in higher education, environmental monitoring of hillslope wetlands, unit hydrograph development for the National Weather Service, snowpack data analysis for the Lake Superior basin, nationwide flash flood guidance estimates, and rainfall intensity patterns. Notable publications include "An Application and National GIS Database to Support 2-year Flood and Threshold Runoff Estimates" (Reed, S., Johnson, D., Sweeney, T.; ASCE Journal of Hydrologic Engineering, 2002), "A subsurface response model for large storm events within the Susquehanna River Basin" (Beighley, R.E., Johnson, D.L., Miller, A.C.; ASCE Journal of Hydrologic Engineering, 2000), "Comparing Mean Areal Precipitation Estimates from NEXRAD and Raingage Networks" (Johnson, D.L. et al.; ASCE Journal of Hydrologic Engineering, 1999), and "The Flood of '96 and its socio-economic impacts in the Susquehanna River Basin" (Yarnal, B. et al.; Journal of the American Water Resources Association, 1997). He was nominated for the 1998 Boggess Award for the best paper in that journal. Johnson teaches hydrology, hydrodynamics, surveying, hydraulic engineering, engineering economy, and wastewater collection systems, and has consulted for the City of Lock Haven, A.C. Miller and Associates, Capitol Engineering Corp., Port Matilda Borough Authority, Michael Baker Jr. Corporation, and Riverside Technology, Inc. He serves as faculty representative to Trustee Committees through 2025 and chairs academic committees.
