Determine hydraulic parameters for an irrigation system

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 'Determine hydraulic parameters for an irrigation system' 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



1. Confirm water delivery specifications for irrigation system

1.1. Soil characteristics are confirmed and hydraulic properties determined.

1.2. Plant/crop water requirements are gathered for various stages of growth.

1.3. Peak water requirements are determined for each area to be irrigated.

2. Determine pressures required to deliver required amount of water over specified area

2.1. Static pressures between water source and delivery points are determined.

2.2. Dynamic pressure necessary to achieve required water volume is calculated.

3. Analyse technical drawings to determine pressure losses through system

3.1. Losses resulting from fittings, laterals and elevation differences are calculated.

3.2. Losses resulting from flow through canals, culverts and pipes of varying sizes and diameters within a system are determined.

3.3. Total friction loss is calculated.

3.4. Hydraulic parameters for system are determined.

4. Select system components to deliver water efficiently

4.1. Water delivery components are selected to achieve the most efficient delivery rate and pressure.

4.2. Flow direction and control components are selected to be compatible with pipes and to achieve minimal friction losses.
