|Abstract: ||Storage yield reliability analysis is used to determine
the volume of water that should be stored in order to
provide a specified water demand with a stated reliability.
Storage depends on the volume of demand D, reliability R
and the hydrology of the catchment supplying the reservoir.
The effect of hydrology of the catchment on the required
storage volume depends upon the temporal uniformity, or
lack of it, of the streamflow and the causal rainfall4. For a
given D and R, a reservoir on a catchment
having substantially variable wet and dry season rainfall,
needs to be larger than if the rainfall is more or less
uniformly distributed throughout the year. The reliability
gives a measure of certainty that a given yield can be met
without failure. Failure in this context was considered as
the interval during which the reservoir is empty. The
reliability is an index between 0 and 1 and can be expressed
in one of three ways (annual, time based and volumetric).
In this study the time-based reliability was used.|
