Page 197 in Davis and Cornwell gives the following data for”mean monthly discharge” (Q, in m 3 /s) for August in the Squannacook River in Massachusetts.A recreational facility has applied for a permit to withdraw water from the river to irrigate itssoccer fields. (a) Prepar a probability plot (lnQ vs probability). (b) Calculate the average flowin the river. (c) How much would you recommend that the facility be allowed to withdraw(assumingthat all of the water would evaporate rather than flowing…
