Ecological
Assessment of Riverine Systems by Combining Information from
Multiple Sources
Mark Handcock, Anthony Olsen and
Joseph Sedransk
The
objective of this project is to improve understanding of
the biological integrity of stream and river systems in
the United States Mid-Atlantic Region by combining
information from separate monitoring surveys, available
contextual information on hydrologic units and remote
sensing information.
We propose to develop
spatial statistical models for measures of biotic
integrity on the streams and rivers that capture the
spatial variation in the measures. These models will be
used to estimate the biotic integrity through the
riverine system based on the information from multiple
sources and scales. We will also quantify the
uncertainty in the estimates and develop methods to
visualize the resulting estimates and
uncertainties.
We hope that the project will be
used as a case-study of how state--of--the--art
statistical methodology can be used to leverage the
information in existing monitoring surveys. For more
information go to an
overview of this project.
