General Notes

The 3.17 release of the TUFLOW Plugin adds additional functionality to the TUFLOW Runner and the Create TUFLOW Project tool. It also adds support for GeoPackage time-series data in TPC files. There are also a number of bug fixes, in particular, some fixes for the ARR to TUFLOW tool.

New Features and Enhancements

TUFLOW Runner - Save and Load Scenarios and Events

It is now possible to save and load the scenario and event sets used for a simulation. This can be useful when simulations have the same or similar scenarios and events. JSON files are used to store the scenarios and events.

Support for TPC Files Referencing GeoPackage Time-Series Data

This version adds support for loading TPC files that reference GeoPackage time-series files. This functionality is only applicable for TUFLOW versions 2025.2 and later. Only SWMM outputs are currently written in GPKG format and written to the tpc file.

Create TUFLOW Project - Adds Additional Settings and Adds Save Globally Option

The option to add the “Tutorial Model” command has been added to the TUFLOW settings tables. This option will only be written to the template control files if the option is set to “On”.

The option to write the settings globally, rather than just for the project, has also been added as a checkbox in the main dialog.

TUFLOW Layer Styling - _bcc_check

Updated styling for _bcc_check. All boundary types are now uniquely coloured and listed in the layers panel.

Import Empty - TUFLOW FV Empty Tooltips

The following TUFLOW FV empty types have had tooltips added to the import empty dialog:

  • 2d_zn
  • 2d_zln
  • 2d_ns
  • 3d_po

Bug Fixes

  • TUFLOW Plugin - Fixed a bug that was introduced in v3.16 where the TUFLOW Plugin would not load in QGIS 3.28.
  • TUFLOW Viewer - Fixed a bug that was causing hover over labels to not display on cross-section plots.
  • TUFLOW Viewer - Vector layers are no longer removed from QGIS when an associated result is removed from TUFLOW Viewer. E.g., if a cross-section result is removed, the corresponding 1d_xs layer is no longer removed from QGIS.
  • TUFLOW Viewer - Fixed a bug where if the “Source” attribute length was zero, TUFLOW Viewer would not recognise it correctly as a 1d_xs layer.
  • ARR to TUFLOW - Fixed a bug in the error handling for the areal temporal pattern downloader. The error was causing the process to crash rather than display the correct error rmessage.
  • ARR to TUFLOW - Fixed a logging error where the pre-burst percentile was hardcoded to report ‘median’ in one location (this was only a logging bug, and the correct pre-burst percentile was being used in the calculation).
  • Create TUFLOW Project - Fixed a bug that was causing the tool to not save the project settings correctly. This caused the older tools to not correctly load the configuration set by this tool.
