ReVA Publications and Presentations
You will find briefings, posters, brochures and a list of publications from ReVA's projects. Descriptions of on-going projects are also available.
The ReVA program will be responsible for the collection, management, and analysis of multiple data sources to evaluate environmental conditions and known stressors within the Mid-Atlantic region. ReVA is being developed to identify those ecosystems most vulnerable to being lost or permanently harmed in the next 5 to 25 years and to determine which stressors are likely to cause the greatest risk. The goal of ReVA is not exact predictions, but identification of the undesirable environmental changes expected over the coming years.

Ground-Water Vulnerability to Nitrate Contamination at
Multiple Thresholds in the Mid-Atlantic Region Using Spatial Probability Models
- The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency's Regional Vulnerability Assessment Program, has developed a set of statistical tools to support regional-scale, ground-water quality and vulnerability assessments. This abstract describes the tools and links to the full scientific investigation report.
Report on the Evaluation of Integration Methods - The Regional Vulnerability Assessment (ReVA) Program has focused initially on the synthesis of existing data. We have used the same set of spatial data and synthesized these data using a total of 11 existing and newly developed integration methods. These methods were evaluated in terms of 1) how well each individual method performs given different data issues that are encountered with existing data, and 2) how effectively each method addresses different types of assessment questions.
ReVA's Web-based Decision-Support System - Guided Tour (.ZIP file) [1.4 MB] - This guided tour demonstrates the ReVA Environmental Decision Toolkit.
ReVA Task Descriptions - Summary information including an abstract, administrative details, and contact information for ReVA projects.
2003 ReVA-MAIA Conference
Presentations - The first ReVA conference was held May 13-15, 2003 in Valley Forge,
PA. This conference focused on work that has been done in our pilot
study in the mid-Atlantic region as part of MAIA (Mid-Atlantic Integrated
Assessment) and also looked ahead to additional research that is
planned as we expand to include additional endpoints (e.g. estuarine
health) in that region and gearing up for a second region. This page contains links to the conference presentations in Powerpoint format.

Final
Stressor Threshold Table (PDF) - This report provides a literature review of ecological variables and their threshold values. The objective was to find studies done with a defined ecological threshold value in the Mid-Atlantic region.
A
Summary of Land-Use Change Projection Models (PDF) - The U.S.
Environmental Protection Agency (EPA) has developed a selective summary of 22 leading land use
change models currently in use or under development. Partners in scoping this effort
include the U.S. Departments of Transportation and Interior, the academic and consulting
communities, and multiple program and regional offices across EPA.
Integrating Economic and Ecological
Models to Assess Aquatic Species Vulnerability (.ppt) - Powerpoint presentation by researchers at UNC-Chapel Hill, NC State University and Duke University.
Stressor Atlas
(PDF) -
The initial phase of ReVA was to develop profiles based on existing information for environmental stressors
across the mid-Atlantic. The objective was to place the data into a common spatial (GIS) format and make it
available for ReVA analyses. This objective required a collaborative, interdisciplinary effort and resulted in the
maps and descriptions in this atlas.
