Assume that the model and initial parameter values were chosen by experts, and therefore represent best guesses, but are not known with certainty. The model consists of the following modules: Reservoir volume evolves as follows: V t +1 = V t- S t- A t + R t (1) where V is volume of the reservoir, S is the release for non-consumptive use (salmon in this model), A is diversion for agricultural purposes, and R is inflow (net of evaporation) into the reservoir. Endangered Sucker fish live in the reservoir. Their population evolves as follows: X t +1 = V t X t e- X t (2) where X is population and the greek letters are parameters. Note that V enters into the growth of the population. Ifgrowth of the population....
