Abstract: A computational framework for the integration of physical process modeling and multicriterion evaluation of river basin operations is presented. Despite a rich tradition in water resources multiobjective programming, most real-world water resources planning relies on simulation followed by ex-post multicriterion evaluation. In this paper we present a computational framework for the integration of modeling and ex-post evaluation by means of object-orientation. Advantages are a simpler, less ambiguous software data model; concurrent computation of physical and multicriterion aspects of a natural resource; efficient locale-specific evaluations; and interactive, interest-specific definitions of evaluatory views. The concepts are tested in the context of simulating and evaluating Colorado River operations.
