View source for TUFLOW CATCH Tutorial M04

= Introduction =
In this module, a TUFLOW CATCH integrated model with interventions is developed. <br>

TUFLOW CATCH Tutorial 04 is built from the models created in <u>[[TUFLOW_CATCH_Tutorial_M02 | TUFLOW CATCH Tutorial 02]]</u> and <u>[[TUFLOW_CATCH_Tutorial_M03 | TUFLOW CATCH Tutorial 03]]</u>. The completed TUFLOW CATCH Tutorial 03 is provided in the '''TUFLOW_CATCH_Module_04\Modelling''' folder of the download dataset as the starting point for this tutorial. 
If unfamiliar with TUFLOW CATCH, it is recommended to complete <u>[[TUFLOW_CATCH_Tutorial_M01 | TUFLOW CATCH Tutorial 01]]</u>, <u>[[TUFLOW_CATCH_Tutorial_M02 | TUFLOW CATCH Tutorial 02]]</u> and <u>[[TUFLOW_CATCH_Tutorial_M03 | TUFLOW CATCH Tutorial 03]]</u> prior to starting this tutorial.

'''Note:''' An NVIDIA GPU card is required to run this tutorial model. If this is not available, a shortened simulation can be run on CPU by updating the following commands in the Global Settings section of the TUFLOW CATCH Control file (.tcc):

:<tt><font color=blue>Hardware </font><font color=red>==</font> CPU</tt>
:<tt><font color=blue>End Time </font><font color=red>==</font> 01/01/2021 12:00:00</tt>

= Meteorological Data =
Meteorological inputs are defined in boundary condition blocks within the receiving model block of the TUFLOW CATCH Control file (.tcc). <!-- reference TUFLOW FV manual when it's done --> For this tutorial, timeseries meteorological data has been supplied.
<ol>
<li>In Windows File Explorer, navigate to the '''TUFLOW_CATCH_Module_04\Tutorial_Data''' folder. Copy the '''TC04_met_ts_001.csv''' and paste it in the '''TUFLOW_CATCH_Module_04\Modelling\TUFLOWFV\bc_dbase\met''' folder. This file contains the timeseries meteorological data.
<li>Open the file. As this file is read by TUFLOW FV, the first column (Time) must contain the date is ISODATE format (DD/MM/YYYY hh:mm:ss). The other columns contain the data for the meteorological conditions that will be simulated in this model: <br>
{|
| 
* '''AIR_TEMP''': Air temperature (degrees Celsius)
| 
:::* '''REL_HUM''': Relative humidity (%)
|-
| 
*'''LW_RAD''': Downward longwave radiation (W m<tt><font color="green"><sup>-2</sup></font></tt>)
| 
:::*'''W10_X''': Zonal wind velocity at 10m (m s<sup>-1</sup>)
|-
| 
*'''SW_RAD''': Downward shortwave radiation (W m<sup>-2</sup>)
| 
:::*'''W10_Y''': Meridional wind velocity at 10m (m s<sup>-1</sup>)
|}

= Simulation Control Files =
The following steps will require use of a text editor. The tutorial demonstration uses Notepad++. For its configuration information refer to <u>[[NotepadPlusPlus_Tips | Notepad++ Tips]]</u>. <br>

==== Generate Template Files ====
This tutorial requires a Water Quality Control file (.fvwq) and a Sediment Transport Control file (.fvsed). Use the TUFLOW CATCH plugin to generate template files:
<ol>
<li>In QGIS, go to Processing > Toolbox from the top drop down menu options to open the Processing Toolbox.
<li>Go to TUFLOW Catch in the processing tool list and select 'Create TUFLOW Catch Project'. This opens the dialog shown below:
*Project Name: '''TC04'''
*Project Folder: Click '...', and navigate to the '''TUFLOW_CATCH_Module_04\Modelling''' folder.
*Project CRS: Click the drop down menu and select 'Project CRS: EPSG:32760 - WGS 84 / UTM zone 60S’.
* TUFLOW HPC Executable: Click '...', and navigate to the '''exe\TUFLOW\2026.0.0 folder'''. Select '''TUFLOW_iSP_w64.exe'''.
* TUFLOW FV Executable: Click '...', and navigate to the '''exe\TUFLOWFV\2026.0.0''' folder. Select '''TUFLOWFV.exe'''.
* Default GIS Format: Click the drop down menu and select 'SHP'.
* Tick on 'Setup Control File Templates'.
* Control File Templates: Expand the 'Advanced Parameters' section. Click '...', and tick on: Water Quality Control file (.fvwq) and Sediment Control file (.fvsed). Ensure all other files are ticked off. 
<li> Click 'Run'. Once the tool has finished click 'Close'.<br>
