Problem

Assume that the Cypress Creek data for 1981-2010 fit a log Pearson 3 distribution (statistics of base 10 logs are Cs = −0.788, mean = 3.8262, Var = 0.05104, and st. dev. = 0.2259). Find the peak flow of the 100-yr flood, and compare it with the peak flow using the entire dataset (14,757 cfs peak 100-yr flood using entire dataset). Explain the difference, knowing that 95% of residential development along Cypress Creek occurred after 1965.

Problem 1

Data for Cypress Creek for the period 1951-2010 are listed on the USGS website. Following the link below, create a table of yearly peak streamflows, and then rank the data. Using these data, develop a relative frequency histogram and a cumulative frequency histogram for Cypress Creek, 1951-2010. Use a class interval of 2000 cfs.
