sch.6-sec.3 Definitions for pt 3

In this part— 2-times base flow event means a post-winter flow year in which the days of flow twice base flow are not more than 4 days fewer than the days of flow twice base flow in the year for the pre-development flow pattern. 2-week lag event means a first post-winter flow event that starts within 2 weeks of the date the first post-winter flow event starts in the same year for the pre-development flow pattern. 5-times base flow event means a post-winter flow year in which the days of flow 5-times base flow are not more than 4 days fewer than the days of flow 5-times base flow in the year for the pre-development flow pattern. 5-week lag event means a first post-winter flow event that starts within 5 weeks of the date the first post-winter flow event starts in the same year for the pre-development flow pattern. daily flow means the volume of water that flows past a node in a day. days of flow 5-times base flow means the number of days in a first post-winter flow event on which the daily flow is at least 5 times the base flow. days of flow twice base flow means the number of days in a first post-winter flow event on which the daily flow is at least twice the base flow. event volume — Event volume means the total daily flows for a first post-winter flow event. However, if the event volume calculated under paragraph 1 is greater than the volume of the estuary of the Fitzroy River, the event volume is the estuary volume. first peak flow — First peak flow means the daily flow on the first day in a first post-winter flow event on which the flow reaches a peak. However, if the first peak flow calculated under paragraph 1 is greater than the daily flow for a flow with a nominal depth of 3m (a 3-metre event ), the first peak flow is the daily flow for a 3-metre event. first post-winter flow event — First post-winter flow event , at a node, means the first flow in a year that— starts between 15 September and 10 April in the year; and either— for node 9A—lasts for 18 days; or for another node—lasts for 21 days; or the chief executive is satisfied meets the following criteria— for node 0— the flow at its start is at least 5,000ML a day; and the event has an event volume greater than half the volume of the estuary of the Fitzroy River; for another node— the flow, within 6 days after its start, is greater than a flow with a nominal depth of 1.5m; and the first peak in the flow that is greater than a flow with a nominal depth of 1.5m happens within 6 days after the start of the event; if the flow starts in September, the water temperature is at least 24ºC; for the duration of the event the flow, at the node, is greater than the base flow for the node mentioned in table 1, column 2. However, a first post-winter flow event does not include a flow that happens in a year in the simulation period for which a flow satisfying the requirements of paragraph 1 did not happen for the pre-development flow pattern. peak flow ratio means the first peak flow for a year expressed as a percentage of the first peak flow for the year for the pre-development flow pattern where the ratio is less than or equal to 1. post-winter flow year means a year in the simulation period in which a first post-winter flow event happens for the pre-development flow pattern. volume ratio means the event volume for a year, expressed as a percentage of the event volume for the year for the pre-development flow pattern, where the ratio is less than or equal to 1. year means a period of 12 months beginning on 1 July.
