Interpretive Summary: This paper summarizes the purpose, methodology, and outcomes of the June 2001 USDA/FEMA Workshop on Issues, Resolutions, and Research Needs Related to Embankment Dam Failure Analysis held in Oklahoma City, OK. The purpose of this workshop was to determine state of the practice, identify short-term and long-term research needs, and to recommend an approach for addressing these needs. Experts presented and discussed the 1) impacts of dam failure, 2) tools available for prediction of dam failure, 3) case histories, 4) present assessment criteria, 5) current research on dam failure, and 6) research needs related to dam failure. Thirty-five participants attended representing state, federal, and private entities from all areas of the country as well as around the world. As a result of the presentations and discussions the workshop participants identified 14 leading research needs with the top 5 as; 1) developing forensic guidelines, 2) developing breach parameter selection guidelines, 3) conducting basic physical model research, 4) developing a better historic data set, and 5) developing better computer-based predictive models. The 14 identified research needs were ranked by the participants based on a qualitative determination of the cost, value, and probability of success of the research needed to address these needs.
