Gc. Dandy et al., COMPARISON OF METHODS FOR YIELD ASSESSMENT OF MULTIPLE RESERVOIR SYSTEMS, Journal of water resources planning and management, 123(6), 1997, pp. 350-358
This paper compares four different methods for estimating the yield of
a multiple reservoir system. These include simulation, a combined sim
ulation-optimization model (WATHNET), a full optimization model, and a
simplified optimization model called the yield model. Simulation is u
sed widely in practice and provides a good approximation of the behavi
or of the system but requires a set of operating rules to be specified
, The optimization methods automatically determine operating rules and
are therefore quite useful in estimating the yield of a new system th
at has not yet been operated. The four methods are used to estimate th
e safe historical yield of the Canberra water supply system (Australia
). It was found that the full optimization model and the yield model p
rovide high estimates of the system yield because they assume perfect
knowledge of future inflows. WATHNET presents a reasonable compromise
in estimating the system yield using implied operating rules that are
achievable in practice.
