On-demand: QGIS for Water Modelling (On-demand-QGIS)

Take sessions anytime, at your own pace with unlimited course access for 30-days.

Learn how to apply free GIS applications and plugins to aid the development and animation of hydrologic and hydraulic models. The course will consist of over 4 hours of content, split into short videos. There is also pre and post course materials to develop and solidify your learning. Don't miss the opportunity to have your questions answered live or via email from industry experts.


QGIS and Catchment Delineation
Learn the generic workflow for stream and catchment delineation for areas where only open data is available. 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

QGIS and Visualisation of Data
The starting point for the second half of the course will be the completion of a catchment delineation analysis. Learn how to take the final data and make a beautiful map showcasing the results. Starting with some symbology tricks, 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
