This course is designed to be highly practical, with x2, 2-hour live and interactive training sessions over two weeks.

This course consists of two live and interactive training sessions. You will build a catchment and stream delineation model step by step with your presenters using QGIS and other tools. You will then run, animate, interpret and troubleshoot your model.

Course Contents:

Session 1- QGIS and Catchment Delineation
In this 2-hour session you’ll learn the generic workflow for stream and catchment delineation for areas where only open data is available. We’ll start with the theory covering the concepts, followed by practical exercises in QGIS. You’ll learn to:

  • Find and download SRTM DEM tiles
  • Mosaic, reproject and subset the DEM
  • Hydrologically correct the DEM by filling the sinks
  • Calculate and visualise the flow direction layer
  • Delineate streams using the Strahler order method
  • Delineate the catchment of a specific outflow point
  • Evaluate the results

Session 2- QGIS and Visualisation of Data
The starting point for this course will be the completion of a catchment delineation analysis. In the second 2-hour session, you’ll learn how to take the final data and make a beautiful map showcasing the results. First you’ll learn some symbology tricks. Then you will then learn the basics of setting up a print composition with standard map elements such as a scale bar, north arrow, legend and locator map. By the end of the course you will have produced an attractive map of the catchment in QGIS and learned some tricks along the way, including:

  • Styling DEMs, rivers, catchments and landmarks
  • Adding Labels
  • Focusing attention on the catchment
  • Setting up a basic print layout
  • Adding standard map elements
  • Using Expressions to enhance the layout
  • Adding a locator map
  • Exporting the final product

The course is delivered through units via the learning platform

  • 2 live and interactive sessions of 2 hours over two weeks
    • Thursday, 20th August 2020, 4-6pm (Sydney Time)
    • Thursday, 27th August 2020, 4-6pm (Sydney Time)
    • Sessions are recorded & uploaded to the learning platform (within 24hrs after session), if you cannot attend live.
  • Pre-and-post-course materials to go through via the learning platform.
  • Exercises between the 2 live sessions.


Pre-course reading and video watching is encouraged. There is also an opportunity to tailor the sessions to your direct questions via the initial survey. After the first week you will be given some exercises to complete, prior to the next session.

Requirements: A good internet connection and software and downloads as described in the learning platform.

Outcome: On completion of the course attendees will be issued with a Certificate of Participation.
