Ordering priorities allow users in Source to specify how shortfalls are prioritised between different demands in Source. Without a priority system enabled, Source will shortfall all demands proportionally within the model. The priority ordering system addresses situations encountered in water resource models such as the following:
...
| Anchor | ||||
|---|---|---|---|---|
|
Scenario | Allow Order | Extract Water | Result |
1 | True | True | Standard case |
2 | True | False | Priorities have no effect on the flow phase. |
3 | False | True | Water will be extracted independently of the priorities |
4 | False | False | No effect |
...
- Maintain downstream ratio
- Override ratios and assign to one priority level (re-prioritise orders - see user guide).
Note: Priority ordering will override ownership if they both turned on in a system. When there is not enough water in the system, borrow and payback will work to make sure higher priority demands get water prior to lower priority demand. |
