Storage reservoirs represent one of the most effective tools for
eliminating, or at least for minimizing, discrepancies in the time
and space variations of water resources distribution and
requirements. In fact, the different - often contradictory - and
increasing demands on water resources utilization and control
usually can be fulfilled only by building multi-purpose reservoir
systems. In this way, the available water resources can be
exploited and/or managed in a more rational way. Typically, the
construction of a dam across a river valley causes water to
accumulate in a reservoir behind the dam; the volume of water
accumulated in the reservoir will depend, in part, on the
dimensions of the dam. The size of the dam will normally affect the
capital expenditure in a very significant way. Indeed the
construction of large water resource control systems - such as dams
- generally involves rather huge manpower and material outlays.
Consequently, the elaboration of effectual methods of approach that
can be used in establishing the optimal reservoir parameters is of
great practical significance. For instance, in the design and
operation oflarge multi-reservoir systems, simple simulation and/or
optimization models that can identify potentially cost effective
and efficient system design are highly desirable. But it should be
recognized that the problem of finding optimal capacities for
multi-reservoir systems often becomes computationally complex
because of the large number of feasible configurations that usually
need to be analyzed."
