Short Biography

Eleanor Griffin is a Research Hydrologist who has been with the National Research Program in Boulder, Colorado since 1993. Her areas of expertise include spatial analyses of geomorphic systems using GIS and application of process-based algorithms to compute streamflow and sediment transport. She has applied these skills to evaluating the susceptibility of streambanks and floodplains to erosion during large floods and to studying processes of sediment erosion and deposition within the Rio Puerco arroyo in New Mexico.

 

Eleanor previously served 5 ½ years as a communication-electronics officer in the U.S. Army and 7 years as a communication systems engineer with a commercial communications corporation (GTE).

 

Education:

 

M.S., 1997, University of Colorado, Boulder, Geology (Focus on Hydrogeology)

B.S., 1980, United States Military Academy, West Point, NY (no major)

Effects of woody vegetation on flow and sediment transport

My work provides a link between the local-scale processes involving erosion, transport and deposition of sediment and landscape-scale effects. Distributions and density of woody vegetation play a major role in determining the outcome of these processes. For the Rio Puerco arroyo, time-series of aerial photographs provide the landscape-scale history of the arroyo, and high-resolution topographic and vegetation data provide the tools to evaluate local-scale processes. Data collected during high-precision field surveys, aerial LiDAR surveys, and mapping from imagery have been combined into a single Geographic Information System (GIS) integrating the local data into the landscape. The integrated dataset provides context for understanding the relation between local and landscape-scale erosion and deposition processes in this semi-arid environment. Process-based algorithms have been applied to in-channel and floodplain flow along the Rio Puerco to explain observed patterns of erosion and deposition. A large flood following saltcedar eradication efforts along the Rio Puerco provided the opportunity to demonstrate the predictive capability of existing algorithms.

 

Predicting the effects of changing climate on a landscape requires an understanding of the connection between regional hydrology and the local stream environment. Process-based algorithms are needed to identify potential alterations of flow timing and magnitude that may have direct impacts on riverine ecosystems. The next direction for my work as a member of an interdisciplinary team will be to use down-scaled climate model predictions to assess potential changes in basin-scale hydrology that may alter the stream channel and floodplain morphology and riparian forest along the Little Missouri River in Theodore Roosevelt National Park, North Dakota.
