Online wflow course Australia

wflow is the Deltares open source modelling framework for rainfall-runoff modelling. It is a completely distributed modelling platform which maximizes the use of earth observation data and calculates all hydrological fluxes at any given location and time step, using physical parameters and meteorological input data.

wflow is used worldwide, in a variety of consultancy and research projects in the field of inundation modelling, flood forecasting, climate change impact evaluation, surface water availability assessment, evaluation of (land) management strategies, etc.

This online wflow course is for hydrologists and water managers interested in distributed hydrological modelling. The course covers the wflow framework and the basics of using the wflow model, through a combination of short presentations, hands-on exercises and interactive sessions, hosted by Deltares wflow experts.

Aim of the course

After taking this course the participants shall understand the basic principles of the wflow model. They are able to use wflow, understand the outputs, and adapt an existing model. The course will provide a starting point for the participants to advance further, by practicing by themselves and making use of the documentation.

In this course the participants learn:

  • A general understanding of the wflow framework
  • How to run a simple wflow model and explore the results
  • How to interpret the results and specify different model outputs
  • How to change parameter values and perform a parameter sensitivity analysis
  • How to adjust model input maps (e.g. substitute a land use map)
  • How to change the forcing data (e.g. rainfall)
  • How to use wflow within Delft-FEWS (basic knowledge of Delft-FEWS is recommended)

Online format

Due to COVID-19, we’ll be providing an online version of this “2-day” course. We will make use of pre-recorded content that you can watch at your own pace. This will be combined with interactive session on 4 consecutive days in the afternoon (14:00-17:00).

The videos will cover all the relevant presentations in 10-15 minutes focused sections. We’ll ask you to watch a playlist of these videos in preparation of each interactive session. The interactive sessions will start with a Q&A of the materials from the videos and continue with relevant exercises. By keeping the group small (with only 6 participants per trainer), we can ensure there is enough time and attention for all questions and discussions.

In preparation of the training, we’ll send you all the material and will ask you to install the necessary software on your machine. While attending the training, it will be essential that you have a sufficiently fast internet connection to support a video call, as well as a headset.


A background in or familiarity with any of the following is recommended:

  • Hydrology and hydrological modelling
  • Basic knowledge of Delft-FEWS (for the session on wflow in combination with Delft-FEWS)

A background in or familiarity with any of the following will be beneficial, but is not necessary:

  • Open-source GIS software QGIS
  • Use of batch files (.bat) and the command line (cmd)
  • Use of text- and csv-files
