Problem 9.10

a. The following data are the average degree-day values ("F/day) and the streamflow (ft³/s) in the South Fork of the Rio Grande at South Fork, Colorado, which drains an area of 216 miº. Compute the daily values of the proportionality constant, K, in Equation 9.6 and the average for the 11-day period. Compare the value with those shown in Table 9.4

b. Using the average value of K determined in part (a) and the following data, compute the snowmelt runoff (ft³/s) using Equation 9.7 and compare the computed and actual runoff, which also are given.
