Abstract
The design capacity of a reservoir depends on the generating mechanism of the inflows. If one uses the sequent peak algorithm in a deterministic manner, the minimum capacity λm required to meet a specified level of demand α is shown to depend on α and the values of the lag 1 serial correlation coefficient ρ and the Hurst coefficient h of the inflows. Although these experimental results may not realistically describe the ranges of the values α, ρ, and h over which other objective functions can be expected to be sensitive to the flow generating model, they do indicate that such ranges exist and that one may have to consider carefully both the list of moments to preserve and the means for their unbiased preservation.
