Reservoir Targets for Urban Water Supply Systems

Morris method of sensitivity analysis applied to assess the importance of input variables on urban water supply yield – A case study

“…They specify the preferred storage volume of individual storages for a given total system storage volume (Perera and Codner, 1996). The Barwon system supplies water to the Geelong City from six reservoirs.…”

“…The long-term optimisation over the planning period is done implicitly by proper selection of long-term operating rules such as reservoir target storage curves and demand restriction rules. These long-term operating rules can be obtained through trial and error simulations or through optimisation techniques (Perera and Codner, 1996).…”

“…However, the operating rules are derived for different levels of annual water demand, thus accommodating the trend of urban water demand due to socioeconomic variables. Perera and Codner (1996) showed that the operating rules expressed in terms of target storage curves were not sensitive to a 20 percent change in demand. Therefore, the approach proposed in this paper to derive the operating rules under various levels of annual demand is considered justified, without considering the variability of these demands due to climatic variables.…”

“…Maximizing volumetric reliability is equivalent to maximizing the yield constrained by the demand. Previously, the annual volumetric reliability has been found to be a satisfactory objective function for determining the optimal operation of urban water supply systems (Perera 1985;Perera and Codner, 1985; Perera and Codner, 1996). Failure probability is also a good measure (i.e., objective function) for urban water supply systems.…”

“…It is important to note that this paper concentrates on the computational improvement methods on SDP as applicable to urban water supply systems, and not on applications and results of SDP. The reader is referred to Perera and Codner (1996) for an application of SDP for an urban water supply system, which uses the developed computational improvement methods.…”
