Description
This unit of competency describes the skills and knowledge required to determine hydraulic parameters for an irrigation system.The unit applies to individuals who apply specialised skills and knowledge to determine hydraulic parameters for an irrigation system. This includes applying and communicating non-routine technical solutions to predictable and unpredictable problems.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Confirm water delivery specifications for irrigation system
  • 1.1 Confirm soil characteristics and determine hydraulic properties
  • 1.2 Determine plant and crop water requirements for various stages of growth
  • 1.3 Calculate peak water requirements for each area to be irrigated
2. Determine pressures required to deliver required amount of water over specified area
  • 2.1 Determine static pressures between water source and delivery points
  • 2.2 Calculate dynamic pressure necessary to achieve required water volume
3. Analyse technical drawings to determine pressure losses through system
  • 3.1 Calculate losses resulting from fittings, laterals and elevation differences
  • 3.2 Determine losses resulting from flow through canals, culverts and pipes of varying sizes and diameters within a system
  • 3.3 Calculate total friction loss
  • 3.4 Determine hydraulic parameters for system
4. Select system components to deliver water efficiently
  • 4.1 Select water delivery components to achieve efficient delivery rate and pressure
  • 4.2 Select compatible flow direction and control components with pipes to achieve minimal friction losses
