Table 3 only presents the parameter importance for the CDD watershed using the NSE. However, all the above procedures were applied to both watersheds and for both efficiency metrics. Table 4 presents the selection ratios and classes of importance for the four considered combinations. A first examination of Table 4 reveals that five parameters (P1, P3, P5, P13, and P22) were consistently identified as the most important in all four cases. At the other end of the spectrum, parameters P7 and P9 were the least important for all cases. The importance of each parameter can be ordered according to the summation of selection ratios for both watersheds and efficiency metrics (the last row in Table 4).
Selection ratio for parameters being important for eight MOGA optimizations using the NSE and TRMSE for both watersheds
