The discusser observes that the paper addresses both the economics and safety of a proposed project without a proper separation of the two topics. Such a separation of the topics, in light of the actual planning, engineering/design, construction and operation/maintenance sequence which results in a completed, functioning dam is presented. The second discusser points out that it may be construed from the paper that reduction of the default value by probabilistic analysis could somehow increase the safety of dams. Such a view would be untenable, as the safety of a dam is determined by physical factors, not probabilistic assessments. The failure of the Telon Dam could be attributed to deficiencies in design. These deficiencies consist of the failure to provide defenses in depth against possible weaknesses in the first line of defense (the impervious core and the grout curtain). In his closure, the author of the paper addresses the issues raised by the discussers.
