Best way to check Cross section data and continuity of cross section capacity

Recommended Posts

As a TUFLOW user in Local Government we are often put in a position to check TUFLOW models.

One aspect that needs checking is the location of cross section data, and the continuity of capacity along various reaches.

That is, the cross sectional area / conveyance progressing from one cross section to the next. I have been searching for tools to do this but as yet have not found anything suitable.

Is anyone aware of such a tool that allows both users and checkers of models to quickly assess the many cross sections that may occur within a model?


I had started working on a python tool and was hoping to find a tool in the QGIS TUFLOW tool ...

Have you looked at the 1d_ta_tables_check.csv file? This reports the calculated hydraulic properties of any cross sections read into TUFLOW.

In QGIS 2 you can load in this check file and view visually in Tuplot - which makes it just a little easier to check. Unfortunately this feature has not made its journey across to QGIS 3 yet. To use follow the steps below:

  1. Open QGIS
  2. Open Tuplot
  3. Click 'Add Res + GIS' - select your 1D resuilts (.tpc file)
  4. Click 'Add 1D Table' - select the 1d_ta_tables_check.csv check file
  5. Open the 1d_xs GIS layer in QGIS
  6. Select 1d_xs layer in Layers Panel
  7. Should now be able to select cross sections and their hydraulic properties - you can also view result water levels on the cross sections
