How would you then modify this definition?

Question 2. A culvert's capacity is deemed inadequate and is to be replaced in 8 years. But DOT engineers are worried about the frequency of the road flooding. If this culvert's maximum capacity before roadway flooding begins is equivalent to flows resulting from a 25-year event, estimate the risk of the road flooding before the culvert is replaced?

Question 3. In the above example, if the acceptable risk of flooding is deemed to be no more than 5%, how much time (months) do the engineers have until the culvert must be replaced?
