Question 3. Calculate the risk for each option below. a) A dam shall be constructed to withstand a flood that occurs once every 10,000 years. The dam is expected to have an economic life of 100 years. What is the probability of a flood exceeding the design flood over the life of the dam? b) The intended design life of a bridge is 120 years and it is designed for a flood expected to occur once in 100 years. What is the probability of seeing a flood greater than the expected one in 100 years during the bridge's design life? c) One bridge foot will be built inside the temporary cofferdam. If the cofferdam is designed for a flood that is expected to occur once in 20 years and will remain in the river for two winters, what is the probability of a flood greater than the design flood?
