The Neosho River originates in Kansas and flows into Oklahoma. Recorded mean-annual-flow Q data (in ) near the state border are:
Make an analysis of the data. Try the normal and lognormal models using probability paper and compare the χ2statistic likelihoods. Which model seems the most reasonable on a physical basis? A rule for allocating the use of the water between the two states is desired. Study the following rule using both probability models: A fixed level x0 for Kansas and an equal value on the average for Oklahoma (that is, 2x0 = mean flow). On the average, how often will Oklahoma have zero allocation under this rule?
