Jessica Z LeRoy, Ph.D.
Dr. Jessica Z LeRoy is interested in applying concepts and techniques from geomorphology and hydrodynamics to help solve real-world problems such as erosion hazards and aquatic invasive species in rivers and lakes.
Jessica's graduate research focused on chute cutoff events on meandering rivers and also included studies on the hydraulic geometry of channels in low gravity environments (e.g., submarine channels and Martian channel features) and the sedimentology of very fine-grained meandering rivers. Jessica joined the U.S. Geological Survey as a Pathways Student Trainee in September 2015 and became a full time Hydrologist in May 2016. Since joining the USGS, she has participated in applied research aimed at mitigating the spread of invasive carps (bighead, silver, and grass carp), as well as projects focusing on scour at bridge piers, beach replenishment, and reservoir sedimentation. She has expertise in using hydroacoustic methods to measure water velocities and bathymetry. She is also currently working on the River Corridors high-value data theme of the National Hydrologic Geospatial Fabric project and is the lead of the CDI Geomorphology Focus Group.

USGS Fluvial Erosion Hazards (FEH) Primer
This primer highlights methods used in regional and reach-scale assessments of fluvial erosion hazards (FEH) . Fluvial erosion includes bed erosion, meaning lowering of the bed of a stream, as well as bank erosion, which refers to the retreat of stream banks that occurs as a stream widens or migrates laterally.
