EPA Office/Lab and LocationA research opportunity is available at the U.S. Environmental Protection Agency (EPA), Office of Research and Development (ORD), Center for Environmental Measurements and Modeling Division (CEMM). The appointment is with the Watershed and Ecosystem Characterization Division (WECD) in Cincinnati, Ohio.

Research ProjectThe EPA’s Office of Research and Development (ORD) in association with the Oak Ridge Institute for Science and Education (ORISE) announces a postdoctoral research opportunity collaborating with a team of EPA/ORD research scientists to characterize the spatial and temporal variability of non-perennial headwater streamflow across several physiographic settings in the U.S.

The extensive headwater stream and interacting riparian network plays an integral part in maintaining clean and plentiful water for aquatic ecosystems and human beneficial uses. Yet modeling non-perennial streamflow throughout the network is difficult, as variable factors including precipitation, physiography and contributing area change in time and space. Concurrently, stream gage data to calibrate and verify model response for non-perennial headwater streams is often limited. Recent advancements in remote sensors, data processing capacities, and statistical approaches are bridging past technological barriers to improve simulations of surface water flows. The improved model outputs advance the underlying scientific understanding of hydrology for baseline conditions and allows for scenario development to characterize the magnitude, duration, frequency, and timing of stream drying under shifting climate conditions.

The focus of this research will be to apply watershed hydrological modeling approaches, in coordination with remotely sensed data (e.g., satellite, airborne), to improve surface flow estimates across non-perennial headwater stream networks. A primary goal of the research is improved lateral and longitudinal characterization of stream drying in low-order stream systems. A secondary goal is to potentially apply climate scenarios to the low order stream system and document the watershed responses. This research will initially concentrate on selected watersheds within the conterminous United States where remotely sensed validation data are available.

The research participant will collaborate with a productive and driven research team of watershed hydrologists and systems ecologists for a one-year postdoctoral research appointment on or around January 3, 2023. The research participant will co-lead multiple publications of the study findings in scientific journals and present at professional conferences. The research participant will gain valuable experience in the applied fields of hydrologic modeling and remote sensing techniques within aquatic systems, be engaged with a collaborative working group, and produce scientific publications that will further our scientific knowledge in the area of aquatic resources.

Learning ObjectivesResearch activities may include:

  • Applying and modifying process-based watershed models (e.g., dynamic TOPMODEL) to answer key research questions
  • Analyzing and interpreting model outputs in the context of current literature
  • Developing research manuscripts and presentations at professional society conferences
  • Collaborating with research scientists in other federal agencies and academia
  • Developing new research questions and directions related to the project’s goals  

Mentor(s)The mentors for this opportunity are Drs. Jay Christensen ([email protected]), Heather Golden ([email protected]), Charles Lane ([email protected]), and Laurie Alexander ([email protected]). If you have questions about the nature of the research please contact the mentor(s).

Anticipated Appointment Start Date: January 3, 2023.  All start dates are flexible and vary depending on numerous factors. Click ere for detailed information about start dates.

Appointment LengthThe appointment will initially be for one year and may be renewed upon EPA recommendation and subject to availability of funding.

Level of ParticipationThe appointment is full-time.

Participant StipendThe participant will receive a monthly stipend commensurate with educational level and experience. Click here for detailed information about full-time stipends.

EPA Security ClearanceCompletion of a successful background investigation by the Office of Personnel Management (OPM) is required for an applicant to be on-boarded at EPA.

ORISE InformationThis program, administered by ORAU through its contract with the U.S. Department of Energy (DOE) to manage the Oak Ridge Institute for Science and Education (ORISE), was established through an interagency agreement between DOE and EPA. Participants do not become employees of EPA, DOE or the program administrator, and there are no employment-related benefits. Proof of health insurance is required for participation in this program. Health insurance can be obtained through ORISE.

ORISE offers all ORISE EPA graduate students and Postdocs a free 5 year membership to the National Postdoctoral Association (NPA).
