Jessica T. Newlin, Ph.D., P.E.
Assistant Professor of Civil and Environmental Engineering

Jessica has an excellent background in civil and environmental engineering and is passionate about studying fluvial systems, numerical modeling of hydrologic and hydraulic systems, and the connections between groundwater and surface water bodies, especially wetlands and streams. She is a core faculty member of the Susquehanna River Initiative, helping shape the vision and mission of the team and creating new teaching and research opportunities for faculty and students.

Jessica has been overseeing the development of a mobile river instrumentation unit, complete with a suite of flow velocity and suspended sediment and bed load sediment sampling gear. Her research is shedding light on the natural history of the Susquehanna River as well as the fingerprint of humans on its tributary watershed and the legacy of logging, canals and railroads, coal, and natural gas industries.

Jessica teaches a variety of watershed-based engineering courses, including river mechanics, sedimentation engineering, and groundwater mechanics class. She is a devoted teacher and scholar who takes her classes into the field for hands-on field-based learning. Her students have installed instruments on campus drainages to monitor flow of water and sediment.

Jessica frequently presents her research at regional and national meeting of scientific and engineering organizations, including the American Water Resources Association (AWRA), American Geophysical Union (AGU), and American Society of Civil Engineers (ASCE). She collaborates with engineers and researchers in a number of agencies including the U.S. Geological Survey, Pennsylvania Department of Transportation, and Susquehanna River Heartland Coalition for Environmental Studies.

Understanding the hydraulics of water and sediment flow in rivers and streams - is critical to understanding the aquatic habitat and management of these resources. I am fascinated by the inter-related complexities of sediment dynamics, flow, habitat, and infrastructure.

The Susquehanna River provides a great opportunity and motivation for continuing to investigate these complex environments.
