The maximum annual peak discharges of the Wonder River for eleven years are given in the following table. a) Prepare a flood-frequency curve using plotting position empirical method. Use the graph provided below to plot the flood-frequency curve. b) According to the flood-frequency curve you constructed: - What would be the discharge during a 20-year flood? - What is the recurrence interval for a flood with a discharge of 1800 cfs? c) A small dam on...

12.4.4. A city depends on the flow of a nearby river for its water supply. If the discharge drops below a base level of 30 m/sec, various emergency actions begin. After two consecutive days of sub-base flow, a small reservoir is brought online; after 10 consecutive days of sub-base flow, water must be piped in from a nearby town. River discharge records have been assessed to determine the excee- dence probability of the two-day drought (70 percent) and the 10-day...

4. Over the last 10 years, a company's annual earnings increased year over year seven times and decreased year over year three times. You decide to model the number of earnings increases for the next decade as a binomial random variable. A. What is your estimate of the probability of success, defined as an increase in annual earnings? For Parts B, C, and D of this problem, assume the estimated probability is the actual probability for the next decade. B....

Historical data suggests that a company has a 26 % probability of reporting an annual earnings increase. Assuming that yearly observations are independent, what is the probability that you will observe exactly 5 increases in earnings over the next 10 years? Enter answer in percents, to two decimal places.

An offshore structure with a design life of 20 years is planned for a site where extreme wave events may occur with a return period of 100 years (i.e. the 100-year wave). The structure is designed to have a 0.99 probability of not suffering damage within its design life. Damage effects between wave events are statistically independent (a) You found in HW 4 that the yearly probability of exceedance of the design wave height is p = 1/100 = 0.01....
