Changelog for TUFLOW Plugin v3.12.1

New Features and Enhancements

TUFLOW Viewer

Speed Improvements For Results With a Lot of Timesteps

Improvements have been made when dealing with datasets that contain a lot of timesteps. This improves load speeds, switching between results, and toggling displaying timesteps as datetime.

FV Tide Boundary Data

TUFLOW Viewer now supports the ability to import FV tide boundary data and plot the resulting water level time series and long plot.

SWMM Processing Tools

Convert - XPSWMM Model from XPX Autofixes for Unsupported BC Configurations

XPSWMM models allow boundary configurations that are not supported by TUFLOW-SWMM. For the configurations below, this tool will make the configurations conform to TUFLOW-SWMM requirements by adding additional nodes and dummy conduits. The modified configurations are hydraulically equivalent.

  1. Nodes with BC inflows and 2D connections are not allowed in TUFLOW-SWMM. The inflow is shifted to a new node which is connected by a dummy conduit.

  2. Outfall nodes with BC inflows are not allowed and are handled the same as case #1.

  3. OUtfall nodes connected to HX boundaries (typically only occur for open channel 1D network connected laterally to the floodplain) are not allowed in TUFLOW-SWMM. In this case, a new node is placed at the outfall location and the outfall is shifted. The outfall is connected to the new node using a dummy conduit.

The figure below shows an example of changes that occur for outfall nodes that both have an inflow assigned and are connected to HX boundaries (laterally) and SX boundaries (flowing out of the outfall). The fix involves creating two new nodes. One node is created at the original location and the other is created offset to receive the inflow. The outfall node is shifted and reconnected to the SX boundary. The junction at the original location maintains its connection to the HX boundaries.

ARR to TUFLOW

ARR Version 4.2 Climate Change Updates

The ARR to TUFLOW tool now uses the latest climate change methodology in ARR Guidelines v4.2. This also fixes a bug that broke the tool with the corresponding datahub update. For more information, please see the following wiki page:
wiki.tuflow.com/QGIS_ARR_to_TUFLOW

Import Empty

The empty tooltips have been updated to reference the 2023-03 manual.

Bug Fixes

Convert TUFLOW Model GIS Format

  • Fixed an issue where Some custom CRS options did not come through cleanly when using this tool.

  • Fixed some warnings that came through about escape sequences that appear begnin.

SWMM Processing Tools

Convert - XPSWMM Model from XPX bugfixes

  • Handle global storm return periods that use non-numeric characters.

  • Convert stand alone nodes with 2D boundary conditions links (HX/SX). Previously upstream or downstream links were required. Without adjacent links the orientation of SX or HX boundaries is arbitrary. A warning to this effect is given on the screen and in the messages file to remind the user to orient them.

  • Improve error messaging if the tbc file cannot be found when parsing the tcf file and allow the rest of the processing to complete.

  • Fix error that could sometimes occur when writing time-series curves.

  • When converting XPSWMM models with hydrology turned off, ignore SWMM rainfall and subcatchments.
