Use of Risk-Based Analysis in Making Decisions on Dam Safety

Abstract

The problem of risk reduction due to dam failure of existing dams with a limited, reasonable expenditure of funds is modeled and solved through the use of quantitative risk-based decision analysis procedures. This approach aids in the identification of which dams are candidates for modification and given that modification is to occur the study can be used to aid in selecting the appropriate type and level of modification to be made. The elements of the procedure as required for practical application to the complex engineering, social, and environmental problem encountered in water resources reliability and risk investigations are illustrated.
