4-Operation Models for Single and Multipurpose Reservoirs -A Review.

Abstract

Reservoir management especially long term planning models for reservoir systems have attracted the attention of many researchers in the water resources management field. In comparison, less effort has been devoted to the development of operational (real time) models and their actual implementation in real life scenario. Some complexities associated with short term or real time operation models may include : smaller time steps, increased uncertainties due to lack of aggregation or lumping effects that is possible for larger time steps, and nonlinearities due to actual operational conditions like water level variations which affect short term benefits and losses more significantly. Some of these associated issues, the importance of real time forecasts, and the criteria for performance evaluation of an operational model are discussed. In this process, models already developed, some of which are being actually used for operation are briefly described.
