The Management Of A Multi-purpose Reservoir
Author(s)

Abstract
This paper addresses the problem of determining the daily operating policy of a
reservoir over a one-year period that satisfies conflicting objectives regarding
hydropower generation, flood control, navigation, and recreational activities.
This optimization problem is stochastic because streamflows are random and can
be forecasted only a few days in advance. One of the difficulties involves taking
streamflow persistence into account and, more specifically, the fact that there
may be long periods of high and low flow. This is important because floods
usually occur during long periods of high flow, while water shortages occur
during long periods of low flow. The paper shows how to solve the problem with
rule curves, Dynamic Programming, and simulation.
Keywords: daily reservoir operation, multi criteria, stochastic optimization, rule
curves, multi-lag autoregressive models.
1 Introduction
This paper deals with the problem of determining the optimal daily operating
policy of a multi-purpose reservoir over a one-year period. The problem is
stochastic because the reservoir inflow is random and cannot be predicted long in
advance. The difficulty in solving this problem stems from the fact that there are
many competing objectives to meet and the daily inflow in usually correlated
with the inflows from the preceding days. The objectives may involve water
quality, the preservation of endangered species habitats, recreational activities,
flood control, water supply, navigation and hydropower generation (Eschenbach
et al. [1]).
The multi-objective reservoir management problem has been the subject of
several publications in the past. A list of these publications can be found in the
survey papers of Yeh [2], Wurbs [3] and Labadie [4,5]. The paper by Cohon and
