Living With Dams: Know Your Risks (2012)
Booklet prepared by ASDSO in conjunction with FEMA to help answer questions about dams: what purposes they serve, associated risks, guidance for those living near dams, and where to find further information. Booklet provides answers to the following questions: (1) Why should I care about dams? (2) What are the risks associated with dams? (3) Could I be affected by a dam? What is the dam failure flood inundation area? (4) Once I determine that my property is in a dambreak inundation area, what's next?

Final Report on Coordination and Cooperation with the European Union on Embankment Failure Analysis [FEMA 602CD]
There has been an emphasis in the European Union (EU) community on the investigation of extreme flood processes and the uncertainties related to these processes. Over a 3-year period, the EU and the U.S. dam safety community (1) coordinated their efforts and collected information needed to integrate data and knowledge with U.S. activities and interests related to embankment overtopping and failure analysis; (2) used the data to improve embankment failure analysis methods; and (3) disseminated the results to the U.S. dam safety community. This final report integrates EU and U.S. research findings and results related to earthen embankment overtopping failure over the 3-year period.

Training Aids for Dam Safety (TADS)
Federal/State developed program designed to train individuals involved with or having responsibility for the safety of dams, including engineers, technicians, dam owners, water resource managers, public officials, and the general public. TADS modules are self-contained, self-paced text supplemented by video presentations. The modules can be used in unique ways to tailor programs to meet individual or organizational needs.
There are 21 TADS modules, arranged in 3 components:
1. Dam Safety Awareness, Organization and Implementation - 5 modules, primarily for dam owners and operators
2. Dam Safety Inspection - 10 modules, designed for engineers with little or no inspection experience, and technicians with some familiarity with dams
3. Data Review, Investigation and Analysis, and Remedial Action for Dam Safety - 6 modules, designed for dam safety program managers, dam owners and operators, and experienced engineers. The emphasis of these modules is on the when, why, and typically what investigations and analyses are conducted.
Order a DVD of the TADS series from FEMA through the link above. Download individual components through the following links:
