Description:

The core of the research effort in the Regional Vulnerability Assessment Program (ReVA) is a set of data integration methods ranging from simple overlays to complex multivariate statistics. These methods are described in the EPA publication titled, "Regional Vulnerability Assessment for the Mid-Atlantic Region: Evaluation of Integration Methods and Assessments Results," EPA/600/R-03/082, October 2003. In the near future, these methods will be implemented in a web-based tool accessible through the ReVA website
