Irrigation System Assessment

Distribution Uniformity

Distribution uniformity is a measure of *
Distribution uniformity compares *
If we can increase the DULQ from ~0.7 to ~0.9 we can effectively irrigate *
If we can increase the DULQ from ~0.7 to ~0.9 we can save *

MATHS!
A grower measured the volume of water caught in 20 buckets after an irrigation event. She measured the volumes and the calculated DULQ was *
For a travelling irrigator, we would consider the result was *
The grower wants to make sure 7/8ths of her plants would receive at least 30 mm of irrigation, so she should set the average applied depth to: *

Pre-season checks

The Compliance checklist helps ensure your system and management *
A compliance check should test that water meter data reaches the regional council *
A compliance check will measure system pressure meets design criteria *
Water supply checks must begin with the system turned on *
Which of the following should be checked with the irrigation system running? *

Irrigator checks

How many checks are recommended as part of a Travelling Irrigator pre-season check? *
Which checks should be made with the system turned off and locked? *
How many checks are recommended as part of a pivot or linear irrigator pre-season check? *
Which checks should be made with the system turned on and operating? *
How many checks are recommended as part of a micro-irrigation system pre-season check? *
Filters should be opened, cleaned and replaced as necessary, before the system is turned on. *
Because of their low pressure, micro-irrigation systems do not need water metering. *
Pressure should be measured *
