摘要

Uncertainty in water resources management is in part about variability and in part aboutnambiguity. Both are associated with lack of clarity because of the behavior of all systemncomponents, lack of data, lack of detail, lack of structure to consider the water resourcesnmanagement problems, working and framing assumptions being used to consider the problems,nknown and unknown sources of bias, and ignorance about how much effort it is worth expendingnto clarify the management situation. The two major sources of variability are temporal and spatialnheterogeneity. Temporal variability occurs when values fluctuate with time. Other values whichnare affected by spatial variability are dependent upon location of an area. A major part of thenwater resources management risk confusion relates to an inadequate distinction between thenobjective risk (real, physical) and subjective (perceived) risk. Because of the confusion betweennthe two concepts, many characteristics of subjective risk are believed to be valid also fornobjective risk. The main objective of this paper is to initiate a discussion of the possiblenmethodology for the reliability analysis of water resources systems that will be capable of:n(a) addressing water resources uncertainty caused by variability and ambiguity, (b) integratingnobjective and subjective risk and (c) assisting the water resources management based on betternunderstanding of temporal and spatial variability of risk.
