Dr. Johnson is a Professor of Civil Engineering. She conducts research in the areas of hydraulic engineering, bridge scour, resilient infrastructure, stream restoration, reliability analyses, and river mechanics. Dr. Johnson is a Past-President and Fellow of the ASCE Environmental and Water Resources Institute (EWRI), the largest institute within ASCE with more than 23,000 members. Dr. Johnson recently received the ASCE Hans Albert Einstein award, and the ASCE-EWRI Outstanding Woman of the Year award. In addition to winning several teaching awards, Dr. Johnson won the National Science Foundation Young Investigator award and in 1995, she won the NSF Presidential Faculty Fellow award. Dr. Johnson has just completed a 3-year project for the NCHRP on Risk-Based Approach for Bridge Scour Prediction. She has published numerous papers in peer-reviewed journals on bridge scour, stream restoration, uncertainty in hydraulics, bridge scour, and stream restoration, and the probability of bridge failure due to scour. She is currently working on vulnerability analyses and risk matrices for bridge crossings, as part of a larger research thrust in resilient infrastructure. These analyses are based on uncertainty in the hydraulic parameters, likelihood of hydraulic occurrences, and conditions at the bridge crossing. Dr. Johnson is also working on developing methods for stable stream channel transitions at bridges that minimize bank/bed erosion, and provide efficient sediment transport or deposition. These methods are partially based on her stream stability assessment method for use at bridge-stream intersections, currently recommended by the Federal Highway Administration. The method is incorporated as part of the Federal Highway Administration’s manual on stream stability at bridges (HEC-20). She has also conducted research on the design of vanes and weirs for protecting bridge foundations for the state of Maryland. This project was based on scaled modeling of flow and geometry at actual scour critical bridges in Maryland. In a related project, Dr. Johnson also recently completed a project in which she tested both laboratory and computer models to assess the use of in-stream structures, such as vanes, to improve sediment transport in streams in northern Pennsylvania where heavy sedimentation affects flooding. Associated with her research and educational goals, Dr. Johnson has supervised the dissertations and theses of dozens of PhD, MS, and BS students. Dr. Johnson currently serves on the ASCE Committee on Diversity and Inclusion, the ASCE Resilient Infrastructure Division and Social Science, Policy, Economics, Education and Decision Committee, and the ASCE-EWRI Education and Research Council.
