Jeremy D Decker, PhD

Jeremy D. Decker is a hydrologist with the U.S Geological Survey Caribbean-Florida Water Science Center and is currently working on the development of groundwater/surface-water models to study the effects of changing climate and sea-level on coastal environments.


Dr. Decker is a hydrologist with the U.S. Geological Survey Caribbean-Florida Water Science Center located in Lutz, Florida.  He completed his B.S. and M.Eng in Mechanical Engineering at the University of Louisville and received his PhD in Mechanical Engineering from the University of Miami.  He has experience with the development of numerical models of groundwater/surface-water flow for a variety of environments.  His work has included numerical code development, data processing and parameter determination as well as future scenario development and testing involving projected climate and sea level. His most recent projects have focused on the potential effects on drainage infrastructure and the increased potential for inundation due to changing sea level and precipitation within southeastern Florida.
