Description
This unit of competency describes the skills and knowledge required to determine hydraulic parameters for an irrigation system.It applies to individuals who analyse information and exercise judgement to complete a range of advanced skilled activities and demonstrate deep knowledge in a specific technical area. They have accountability for the work of others and analyse, design and communicate solutions to a range of complex problems. All work is carried out to comply with workplace procedures.No occupational licensing, legislative or certification requirements are known to 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 the most efficient delivery rate and pressure
  • 4.2 Select compatible flow direction and control components with pipes that will achieve minimal friction losses
