Abstract:

In November 1984 the Surface Water Hydrology Committee appointed a task committee with the assignment to suggest standards for the hydrologic safety design of dams. The committee report recommends procedures for selecting the safety design flood for a dam assuming that flood and dam failure probabilities have been defined. The recommended procedures utilize a risk-based analysis which compares the likelihood of dam failure to the social, economic, and environmental consequences directly attributable to dam failure. The financial analysis proposed for incorporating into the design decision those failure consequences which can be quantified in monetary terms is based upon the estimated cost to fully indemnify possible victims for their financial loss. A separate assessment is used to include into the decision the social and environmental impacts not measurable in monetary terms.
