Table 1. Probabilities of the different states, i.e., possible discharges, under three different climate scenarios, e.g., current, climate change low, and climate change high. For each investment, the returns, expressed as prevented damage loss, are showed for each possible states A, B, C, and D (from DWW 2005a, 2005b).
