An example consistent with the restrictions above is provided in the figure below. This figure shows that the change in Restriction Level (shown on the y axis on the right) goes from Level 0 to Level 1 at 60% storage and from Level 1 to Level 2 at 45% storage as storage volumes are getting lower and then returns from Level 2 to Level 1 at 55% storage and Level 1 to Level 0 at 70% storage.
The Restriction Curves approach provides a look-up table for Restriction Level that is dependent on the antecedent stored water volume conditions. When applying the Restriction Curves in a Source model the Restriction Level is used to adjust the time series demand for water supply.
