What an assessment for NWPHYD007 must cover

50 assessable components: 4 elements (26 performance criteria), 14 performance evidence and 10 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare for discharge measurement

  • 1.1Identify hazards, assess risks and implement control measures according to workplace procedures
  • 1.2Identify the monitoring objective of the work measurement or monitoring site and gauge requirements
  • 1.3Identify, analyse and confirm data collection methods appropriate to site conditions
  • 1.4Select appropriate equipment and instruments to meet site conditions
  • 1.5Verify calibration and maintenance status of equipment according to manufacturer instructions and workplace procedures
  • 1.6Evaluate and prepare site to take discharge measurements according to workplace procedures
  • 1.7Identify influences on discharge measurement
  • 1.8Select cross-section for discharge measurement according to workplace procedures

2 Collect depth and velocity data

  • 2.1Measure the width of the section according to workplace procedures
  • 2.2Select appropriate sounding points and verticals to subdivide the cross-section
  • 2.3Measure the depth of vertical using method suited to site conditions
  • 2.4Select appropriate velocity measurement method to suit flow and cross section conditions
  • 2.5Collect velocity data at appropriate depths for each vertical

3 Calculate discharge

  • 3.1Calculate the point velocity according to workplace procedures
  • 3.2Calculate the mean velocity for each vertical
  • 3.3Calculate the area of subsection corresponding to each vertical
  • 3.4Calculate the discharge corresponding to each subsection
  • 3.5Calculate the area and discharge at the section by summation of the subsection data
  • 3.6Apply corrections for oblique flow when required

4 Record and document discharge measurement

  • 4.1Gather supporting information from the site and complete measurement documentation
  • 4.2Calculate and record the mean stage height and rate of change using relevant mathematical techniques
  • 4.3Grade and record the gauging quality according to workplace procedures
  • 4.4Check measurement computations and record results in database according to workplace procedures
  • 4.5Compare discharge measurement to site rating curve and note deviation
  • 4.6Enter gauging results into database according to workplace procedures
  • 4.7Report site issues or significant deviations from ratings to relevant personnel and stakeholders

Performance evidence

  • analysing and verifying data using workplace procedures, software and databases
  • assessing risks and taking appropriate precautions and/or actions
  • collecting, entering and archiving data
  • collecting field measurements
  • communicating with employees and customers
  • gathering, interpreting and applying documentation related to the specifics of hydrological data collection and reporting procedures
  • identifying potential or actual operational problems
  • identifying, reporting and solving potential or actual problems within scope of job function
  • interpreting and applying technical documentation
  • maintaining testing equipment in good order and verifying calibration
  • performing calculations including mean velocity in a vertical
  • preparing documentation
  • using positioning or distance measurement equipment
  • using safety equipment and personal protective equipment

Knowledge evidence

  • area velocity methods including: - acoustic Doppler current profiler - Doppler velocity meter - electromagnetic current meter - mechanical current meter
  • appropriateness of measurement methods
  • measurement equipment and quality assurance methods
  • measurement section issues and solutions
  • relevant legislation, industry standards, workplace policies and procedures including: - Bureau of Meteorology - International and Australian Standards - WHS - World Meteorological Organisation
  • relevant technology
  • relevant workplace procedures
  • suitable measurement sections, attributes and issues
  • turbulent and laminar flow
  • workplace documentation for data and reports

Questions about assessing NWPHYD007

What does an assessment tool for NWPHYD007 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for NWPHYD007 needs to address all 50 unit components: 4 elements with 26 performance criteria, 14 performance evidence requirements, 10 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for NWPHYD007?

Auditori pulls the current release of NWPHYD007 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for NWPHYD007 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing NWPHYD007 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of NWPHYD007, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
