4.3 Initialisation

TUFLOW CATCH requires construction of a suite of folder substructures to support simulations. These should be all co-located at the same folder level underneath a single directory that sits within an overall project directory. These substructures correspond to each of the three products potentially used in a TUFLOW CATCH simulation, and should be named as follows (with ‘TUFLOW’ referring to TUFLOW HPC):

• TUFLOW
• TUFLOWCATCH
• TUFLOWFV

Each of these substructures has its own subfolder arrangement, consistent with those suggested for standalone TUFLOW HPC and TUFLOW FV modelling studies. For consistency, the suggested TUFLOWCATCH subfolder arrangement is also similar.

To assist with this set up, and indeed more broadly with the initialisation, execution and results interrogation of a TUFLOW CATCH simulation, a freely available TUFLOW CATCH QGIS plugin has been developed:

• The TUFLOW CATCH plugin (as a zip file) can be accessed here
• Instructions on installing TUFLOW plugins (including the TUFLOW CATCH plugin) from zip files is provided here.

Further resources related to using the TUFLOW CATCH plugin are provided on the TUFLOW Wiki.
