Question

Problem1 A recreational park is built near a stream. The stream channel can carry 200 m3/s, which is the peak flow of the 5-yr. storm of the watershed. Find the following: (a) The probability that the park will be flooded next year. (b) The probability that the park will be flooded at least once in the next 10 years (c) The probability that the park will be flooded 3 times in the next 10 years. (d) The probability that the park will be flooded 10 times in the next 10 years Problem 2 a Find the 5-year and 100-year rainfall intensities (X, and assuming a lognormal distribution with ma 0.43 and standard deviation S, -0.12 b) Assuming a lognormal distribution with mean log0.89 and standard deviation S,0.10, find the exceedance probability and retun period for rainl intensities X 0.22 in./hr and 0.28 in./hr
