ABSTRACT
Gradual shift has been observed lately of dam safety procedures from the
conventional technical based towards a wider scope of risk management procedure
based on risk analysis. The new approach considers the likelihood level of
occurrence of a multitude of hazards and the magnitude of the resulting
possible consequences in case of failure using rational cause and effect
arguments. Most dam owners are shifting towards the use of the new risk based
procedures; and even governments themselves are moving towards formalizing the
new trend. Legislations in the United States were promulgated [1] after serious
dam failures and the adoption of stringent levels of scrutiny led such federal
dam owners to pioneer in this field and in developing the concepts and methods
required. The corner stone in risk analysis is the definition of the potential
modes that may lead to failure and assessment of the likelihood levels of their
occurrence and possible category of the consequences which, after thorough
evaluation, will shape the
decision making. This type of analysis was applied to Mosul Dam as a case study
and resulted in definite recommendations.
