摘要: This paper presents a Sensitivity Analysis (SA) of the input variables used in estimation yield, considering multiple 20 year hydroclimatic scenarios system inflow, rainfall, evaporation and demand. The Barwon urban water supply Australia was considered as case study, whilst extended Fourier Amplitude Test (eFAST) method for SA. Input simulation model were divided into two categories use SA analysis: climate dependant (i.e. demand) to generate various scenarios, policy which assumed have knowledge deficiency relation their optimum values. security thresholds found be most important variables, followed by upper restriction rule curve position. remaining variable did not show discernible trend, indicating sensitivity inflow variability rather than total volume. yield estimate increase increased. However had wide range increased showing that behaviour is particularly sensitive variability.
