• Description:
  The Bridges Decision Support Model is a geographic information system (GIS) that assembles existing
  
  data on archaeological sites, surveys, and their geologic contexts to assess the risk of bridge replacement
  
  projects encountering 13,000- to 150-year-old Native American sites. This project identifies critical
  
  variables for assessing prehistoric sites potential, examines the quality of available data about the
  
  variables, and applies the data to creating a decision support framework for use by the Iowa Department
  
  of Transportation (Iowa DOT) and others. An analysis of previous archaeological surveys indicates that
  
  subsurface testing to discover buried sites became increasingly common after 1980, but did not become
  
  routine until after the adoption of guidelines recommending such testing, in 1993. Even then, the average
  
  depth of testing has been relatively shallow. Alluvial deposits of sufficient age, deposited in depositional
  
  environments conducive to human habitation, are considerably thicker than archaeologists have routinely
  
  tested.
