If you are using QGIS as your model development or result viewing environment we strongly recommend installing the TUFLOW QGIS Plugin. It includes numerous tools to increase workflow efficiency. It also includes powerful result viewing functionality via its TUFLOW Viewer. This page describes the process of installing and using the Plugin.

Installation of Plugin

To enable the plugin please follow the instructions below:

  1. Download the plugin from the QGIS official repository, Plugins >> Manage and Install Plugins
  3. In the manager, search for "TUFLOW".
  4. Select TUFLOW, and "Install Plugin".
  6. Once enabled the plugin should be accessible from the Plugins >> TUFLOW menu item:
  8. Before using, check that the prerequisite python modules are also installed (see below).

Development Version

It's possible to test out the latest development version of the plugin and TUFLOW Viewer by following the instructions below:
Installing the Latest Development Version of the TUFLOW Plugin


The TUFLOW plugin uses the following python modules which may need to be separately installed. These may have been installed with other software, to check if they are installed on your machine:

  1. Install the TUFLOW plugin (see instructions above)
  2. Open the TUFLOW plugin Plugins >> TUFLOW
  3. Check that the required dependencies are installed from the menu. TUFLOW >> About >> Check Python Dependencies Installed.

All going well you will get a notification to tell you that the required modules are installed. If not, you will be notified if you need to install either of the python modules below:
Please ensure QGIS / python is installed before installing the below.


Each function in the utility has a separate page documenting the usage.

The first step for a project is to create the project / save the settings with the Create or Configure TUFLOW Project tool. Subsequent tools rely on the information stored at this stage to work best.

Error While Upgrading Plugin

If you receive an error while trying to upgrade the TUFLOW plugin you may need to either:

  1. Restart QGIS and try upgrading the plugin again
  2. Manually remove the old version

Errors are most likely caused by an issue with deleting the old version of the plugin as some part of the plugin is still being used somewhere in memory (RAM) and locking permissions. This is a known issue that occur with the ReFH2 to TUFLOW tool in older versions of the plugin. Simply restarting QGIS and retrying the upgrade process should fix the issue.

Manually removing the TUFLOW plugin

To manually remove the TUFLOW plugin simply delete the 'tuflow' folder from the QGIS plugin directory (you may need to close QGIS first):

  1. Windows - %appdata%\QGIS\QGIS3\profiles\default\python\plugins
  2. Linux - /home/USER/.local/share/QGIS/QGIS3/profiles/default/python/plugins
