Days between floodplain inundation events
4 Days between floodplain inundation events
An environmental flow objective for surface water to which this plan applies is that the performance indicator mentioned in subsection (2) is not more than what the performance indicator was immediately before the commencement.
The performance indicator, for nodes A to L, is the total number of days in all intervening periods for each node as a percentage of the total number of days in the simulation period.
In this section—
floodplain inundation event, for a node, means a daily water flow at the node that is equal to or more than the flow rate at which the floodplain starts to fill, as stated for the node in the following table.
intervening period, for a node, means a continuous period of more than 4 years and 7 months, during the simulation period, between floodplain inundation events for the node.
| Node | Fill commencement threshold (ML/day) |
| A | 8,400 |
| B | 6,100 |
| C | 10,000 |
| D | 7,100 |
| E | 17,000 |
| F | 82,000 |
| G | 2,300 |
| H | 47,000 |
| I | 22,000 |
| J | 19,000 |
| K | 52,000 |
| L | 23,000 |
