IRR400 Principles of Irrigation (8)

This subject provides an introduction to soil-water-plant-atmosphere relationship and soil moisture measurement techniques for irrigation scheduling. A study of open channel and pipe hydraulics and its application to study the principles of gravity, drip, and sprinkler irrigation. Recycled water and wastewater use for irrigation.
Distance Education students are required to attend a compulsory residential school as a requirement for this subject.

Learning Outcomes

Upon successful completion of this subject, students should:
  • be able to assess soil water status and deduce its availability to plants
  • be able to calculate crop water requirement and evaluate different approaches
  • be able to apply basic hydraulic principles to choose a pipe and open channel flow system which minimises pressure loss
  • be able to evaluate gravity and pressurised irrigation system using different performance indices
  • be able to design a small scale pressurised irrigation system: choose appropriate dripper, sprinkler, and pump products
  • be able to assess irrigation water quality in terms of physical and chemical properties and propose control/management methods

Syllabus

This subject will cover the following topics:

Irrigation: World and Australian Context
Irrigation and global food security, irrigation in the Australian context, irrigation productivity and irrigation sustainability;

Soil-Plant-Water-Atmosphere Relations
Soil-plant-water relations, soil moisture measurement, crop water requirement, irrigation water requirement and irrigation scheduling;

Open Channel and Pipe Hydraulics
Open channel hydraulics, pipe line hydraulics and irrigation pumps

Irrigation Systems
Irrigation system layout, surface (gravity) irrigation methods, surface irrigation performance, sprinkle irrigation, microirrigation, waste and recycled water use;

Environmental impacts of irrigation

Residential School

This subject contains a 3 day Compulsory Residential School.

The residential school provides a practical approach to the theories taught in the subject.
The students will gain practical knowledge from attendance at lectures, tutorials, lab practicals and field trips to irrigation areas.

Special Resources

Students are required to attend the compulsory residential school which will involve travel expenses and a time commitment.
