Note: Sensitivity was calculated following Jøgensen (1986). (See Eqn. A2.16 in Appendix 2.) The final phosphorus load reduction (%) after 50 yrs was used as the state variable to determine sensitivity relative to results for identical MEF when MCF = 1.25. For example, the final phosphorus load reduction for MEF = 1.50, MCF = 1.50 (37%) was compared to the final phosphorus load reduction for MEF = 1.50, MCF = 1.25 (39%) to determine a sensitivity of 0.26. Results indicate that the system was not significantly sensitive to the value of MCF.
