FIG. H1. This figure is analogous to Fig. F1, but the trajectories correspond to those in the lower left panel of Fig. G1. The blue trajectory starts in the upper part of the green area in Fig. G1, and the red trajectory starts in the lower left part of the green area. The green trajectory starts in the right part of the green area in Fig. G1, and the cyan trajectory starts in the blue region. The time interval used here is too short to show that the cyan trajectory eventually reaches the diamond in the blue region. Axes labels: L = load of P in kilograms per square meter per year, P = concentration of P in lake in kilograms per square meter, M = concentration of P in mud in kilograms per square meter, and PV = present value.
