Abstract

Water resource systems have been an important part of resources and environment related research at IIASA since its inception. As demands for water increase relative to supply, the intensity and efficiency of water resources management must be developed further. This in turn requires an increase in the degree of detail and sophistication of the analysis, including economic, social and environmental evaluation of water resources development alternatives aided by application of mathematical modeling techniques, to generate inputs for planning, design, and operational decisions.

During the year of 1978 it was decided that parallel to the continuation of demand studies, an attempt would be made to integrate the results of our studies on water demands with water supply considerations. This new task was named "Regional Water Management" (Task 1, Resources and Environment Area).

This paper is concerned with operational decision-making in the existing multiple reservoir systems. Following a short description of the case system, three different approaches to optimization of the system's operation are presented. First, the three-step stochastic implicit approach; second, the simulation approach; and third, the approach based on the concepts of hierarchical control systems. Distinction is made between the long-term reservoir operation rules and the short-term operational decisions using the real-time forecasts of reservoir inflows and water demands.

The paper is part of a collaborative study on the operation of the Upper Vistula multiple reservoir system in Poland, carried out by the Institute for Meteorology and Water Management, Warsaw, Poland and IIASA.
