Abstract

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.

Learning Outcomes

Upon successful completion of this subject, students should:
  • be able to compute plant available soil water and interpret soil-water relations
  • be able to calculate water requirement of horticultural and broad acre crops
  • be able to apply basic hydraulic principles to determine pressure requirement and head loss in pipe and open channel flow systems
  • be able to explain the efficiency of a surface irrigation event and evaluate distribution uniformity of drip and sprinkler irrigation systems
  • 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 determine the leaching requirements

Syllabus

The subject will cover the following topics:
