The spillway of the large dam is designed by you for 58 years-flood and its cofferdam for 8 years-flood. The lifetime of the dam is 63 years, and the construction period of the dam is 5 years by the specification you signed. Determine: a) The risk of the spillway for its design flood. b) The risk of the cofferdam for its design flood. c) The probability that the design flood of the spillway occurs twice during the construction period of the dam.

Probability plotA bridge will be built over the Meherrin River near the site that the discharge measurements were taken for the log-normal probability plot below. The service life of the bridge is 40 years. If a design discharge of 23,000 cfs is used for the bridge: (a) what is the probability that the bridge will be flooded in any one year? (b) What is the probability that the bridge will be flooded at least once over its service life? (Note: just focus on the “theoretical line” in the plot)
