Under the Operations tab six different operating rules can be specified:
1. Minimum release requirement (optional): release required to support environmental flows in the river downstream of the reservoir. This release takes place as long as the water level is above the Dead zone level (Top of dead storage).
2. Maximum release requirement (optional): a restriction on the flood control release when the water level in the Reservoir is above Flood control level (or Spillway bottom level, if defined).
3. Minimum operation level requirement (optional): the minimum level at which water is supplied to water users. Below the minimum operation level, only minimum flow requirements are released. If minimum operation level is not specified, the model uses the Dead zone level (Top of dead storage) as the minimum operation level.
4. Flood control level time series (mandatory): the level above which water is released for flood control purposes.
5. Guide curve level (optional only for allocation pool reservoirs): the level below which the Reservoir is ‘divided’ into pools.
6. Pool ownership for downstream river time series (mandatory only for allocation pool reservoirs), cf. 9.3.3
All operation rules are specified as time series. This is done by enabling the relevant operating rule (for optional rules) and specify the time series
by clicking on the button and selecting Browse to include an existing time series or selecting Create a new file to open the ‘Create a new file’ dialogue.
Note that minimum and maximum release requirements may be influenced by remote flow requirements (cf. Remote Flow Control).
Based on the rule curve levels and reservoir characteristics, Reservoirs can be divided into different zones depending on the type of reservoir.
