Surface Water Hydraulics
Surface Water / Groundwater Interaction
Subsurface Contaminant Migration
Effectiveness of Remediation Alternatives

Profile

For over 30 years Dr. Lennon has conducted studies on groundwater hydrology and surface water hydraulics, surface water/groundwater interactions, and subsurface contaminant migration. He has published more than 70 papers in journals and conference proceedings, and he has received funding from the National Science Foundation, the National Oceanographic and Atmospheric Administration, the U.S. Environmental Protection Agency, New Jersey’s Department of Environmental Protection, the U.S. Geological Survey, the Mellon Foundation and other agencies. Dr. Lennon’s work includes field and laboratory studies as well as modeling ground and surface water flow, subsurface contaminant migration, effectiveness of containment and remediation alternatives including barrier walls, and estimation of fluid expulsion from geothermal vents in the Oregon Accretionary Prism in the Pacific Ocean. The Oregon work sent Dr. Lennon on two of the project’s 13 Alvin Submersible dives. He is a co-author of the U.S. Army Corps of Engineers’ “Design Manual for Fluidization Systems.”

Dr. Lennon’s current research focuses primarily groundwater contamination studies with Dr. Derick Brown. 

 

Teaching and Service

Dr. Lennon served as a Rossin College Associate Dean and then Deputy Provost for Academic Affairs, returning to the Civil and Environmental Engineering faculty in 2013.

Dr. Lennon’s teaching experience includes sophomore-level graphics and design, fluid mechanics, environmental groundwater hydrology, water resources engineering, introduction to engineering practice, and transportation engineering.. He has directed or co-directed about 20 graduate students for M.S. and Ph.D. degrees. His awards include the Lehigh Class of 1961 Professorship, the Lehigh Junior Award for Distinguished Teaching, the Lindback Foundation Award for teaching excellence by a senior member of the faculty, and the 2018 Rossin College Award for Experiential Learning. Currently he is leading the development of a chapter of the National Academy of Engineering’s Grand Challenge Scholars Program at Lehigh.

 

Selected Publications and Presentations

Dr. Lennon and his colleagues Mark Connar and Mike Kaas were each invited to give a presentation at the Society of Industrial Archeology's annual conference in June 2018; the Lehigh site described by those papers is the subject of the cover and lead paper of the winter edition of their SIA Newsletter.
