Unformatted text preview: (not just CSOs). Briefly describe two hypothetical scenarios (agricultural or urban) besides CSOs: One scenario where a first flush occurs, and one scenario where a first flush does not occur. Problem 5. Assume that the Pb data in Box 3.2 are annual maximum EMCs for 1997 through 2005. Estimate the median, 90th, and 95th percentiles: 1) nonparametrically with Eq. 3.12, 2) assuming a normal distribution, and 3) assuming a lognormal distribution. Estimate the twoyear, 10year, and 25year return period EMCs assuming a normal and lognormal distribution. What is the longest returnperiod EMC than can be estimated nonparametically?...
