• Abstract:
  This report documents the development and testing of a field-deployable, knowledge-based decision support system that assists bridge inspectors by acquiring, cataloging, storing, and retrieving information necessary for the evaluation of a bridge for the presence of scour. More importantly, the expert system provides an independent scour risk evaluation of the site conditions, evaluates the bridge and substructure elements for failure risk, and provides both explanations of the scour risks and suggestions for scour mitigation. The contents of this report are, therefore, of immediate interrest to both highway and rial transit professionals responsible for operating, inspecting, maintaining, and upgrading scour susceptible sctructures. The report is also of interest to those charged with overall system safety and budgets as well as to policy makers.
