Apply principles of open channel hydraulics

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Reference books for 'Apply principles of open channel hydraulics' on This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to for every purchase, so go nuts :)

Elements and Performance Criteria



Elements describe the essential outcomes

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section.

1. Select open channel hydraulic methodology

1.1 Identify monitoring objectives of the site and hydraulic calculation requirements.

1.2 Select methodology for open channel hydraulic calculations.

1.3 Identify hydraulic principles used for verification of calculations.

1.4 Select other methodologies to review initial calculations.

2. Collect and review data for flow calculations

2.1 Measure and collect appropriate data to calculate theoretical flows based on methodology selected.

2.2 Determine the hydraulic characteristics of a monitoring site.

2.3 Measure and collect appropriate data to calculate flows theoretically.

2.4 Estimate hydraulic coefficients based on observations.

2.5 Prepare records in a format suitable for dissemination.

2.6 Review data collected and subsequent calculations for inconsistencies against measured flows.

3. Select the appropriate control structure

3.1 Select the appropriate control structures based on the characteristics of the open channel and its catchment.

3.2 Identify and determine the method to calculate flow by using the appropriate formulae for the control structure.

4. Calculate flow in open channels

4.1 Select and use the appropriate formulae for calculating flows in open channels based on the characteristics of the open channel and its catchment.

4.2 Identify the limitations of the formulae.

4.3 Identify factors that would cause variations in the results.

4.4 Verify results by applying hydraulic principles and other methodologies.

4.5 Determine the characteristics of open channel pipe flow.

5. Calculate flow from pressure measurements

5.1 Determine flow-based calculations by using pressure instruments.

5.2 Make adjustments for absolute pressure instruments to measure head in open channels.

5.3 Make corrections in pressure measurements to allow for head measurement of salt water.
