Abstract

The purpose of this workshop was to discuss, compare and evaluate various methods of operating, and determining operating policies for multi-purpose, multiple reservoir systems. While total reservoir capacities are known, the allocation of various storage volume zones within the reservoirs to various purposes, such as water supply or flood control, may vary in time and be dependent on reservoir operating policy. In the guidelines for preparation of the papers included in this volume, it was stressed that discussion should cover reservoir operation for all possible hydrological situations, i.e., in periods of flood, normal flow, and drought conditions. The importance of procedures used to determine when an extreme situation (such as drought), begins and ends, was emphasized, especially with respect to possible changes in reservoir operation. The participants were requested to discuss how operating policies might differ, depending on whether the reservoirs are in series or are parallel. Also, they were requested to distinguish between operation of "large" over-year storage reservoirs and "small" within-year storage reservoirs. If short-term hydrological forecasting and real-time control models were to be used, the workshop discussion would consider how these could be used together with long-term operating policies.

Some 30 participants from 13 countries presented 17 papers at the workshop, all of which are included in these proceedings. The first nine provide an overview of how multiple reservoir systems are operated in certain countries. The remaining papers report in more detail on diverse case studies and provide discussion of some specific issues related to the subject of the workshop.
