6.2 Core supported configurations

The three core supported configurations of TUFLOW CATCH are:

  • Hydrology
  • Pollutant export
  • Integrated

The outputs of these are described in the following sections. In all cases, the TUFLOW CATCH control file is assumed to be named Model_001.tcc. It is strongly recommended that TUFLOW HPC and TUFLOW FV results that are to be used to create a TUFLOW CATCH *.json file for viewing in QGIS are output at the same timestep, referred to as <common_dt> below.

Units for all constituents, where relevant, have been set as standard (typically mg/L) to accord with commentary provided in Sections 4.5.3.1, 4.5.3.2 and 4.5.3.3.3.

6.2.1 Hydrology

6.2.1.1 Data types

It is recommended that the following data types be set, assuming salinity and temperature are included as constants/timeseries. If not, then catch (TUFLOW HPC) and , sal, temp (TUFLOW FV) can be omitted. If soil layers are not simulated then GW_QZ and GW_QZI should also be omitted (doing so will also reduce output file size if necessary):

TUFLOW HPC

Map Output Format == XMDF
Map Output Data Types == V d h catch GW_QZ GW_QZI
Map Output Interval == <common_dt>

TUFLOW FV

Output == NetCDF
   Output Parameters == h,v,d,sal,temp
   Output Interval == <common_dt>
   Suffix == HD
End Output

6.2.1.2 Files

The following output files are produced in the execution of a hydrology simulation with data types as above. Each is a 2D or 3D (TUFLOW FV) map output that varies in time:

  • TUFLOW HPC
    • Model_001_catchment_hydrology.xmdf
  • TUFLOW FV
    • Model_001_receiving_HD.nc
      • Bed Elevation
      • salinity
      • temperature
      • velocity
      • vector Velocity
      • water depth
      • water surface elevation

6.2.1.3 Interrogation

The above output files can be viewed either:

  • Individually via the TUFLOW Viewer (File -> Load Results -> Map Outputs), and interrogated using usual TUFLOW Viewer techniques, or
  • Simultaneously via use of the Create TUFLOW Catch JSON function demonstrated in the eLearning material described in Section 4.3

6.2.2 Pollutant export

In this example, it is assumed that two pollutants are simulated (in addition to temperature and salinity), as:

  • PFAS, Washoff1 pollutant export model
  • Tailings, Shear1 pollutant export model

These models have been chosen because they produce different outputs.

6.2.2.1 Data types

It is recommended that the following data types be set:

TUFLOW HPC

Map Output Format == XMDF
Map Output Data Types == V d h catch GW_QZ GW_QZI GW_MZ GW_MZI
Map Output Interval == <common_dt>

TUFLOW FV is not activated.

6.2.2.2 Files

The following output files are produced in the execution of a pollutant export simulation with data types as above. Each is a 2D map output that varies in time. Hyperlinks are provided to detailed descriptions in the appendices for representative pollutants:

6.2.2.3 Interrogation

The above output file can be viewed via the TUFLOW Viewer (File -> Load Results -> Map Outputs), and interrogated using usual TUFLOW Viewer techniques.

6.2.3 Integrated

In this example, it is assumed that one sediment fraction and inorganic simulation class water quality are simulated (in addition to temperature and salinity), as:

  • oxygen, silicate, adsorbed phosphorus and phytoplankton as constants
  • all other water quality pollutants, Washoff1 pollutant export model
  • fines, Shear1 pollutant export model
  • salinity, constant
  • temperature, timeseries

These models have been chosen because they produce different outputs.

6.2.3.1 Data types

It is recommended that the following data types be set:

TUFLOW HPC

Map Output Format == XMDF
Map Output Data Types == V d h catch GW_QZ GW_QZI GW_MZ GW_MZI
Map Output Interval == <common_dt>

TUFLOW FV

Output == NetCDF
   Output Parameters == h,v,d,sal,temp,sed_1
   Output Interval == <common_dt>
   Suffix == HD
End Output

Output == NetCDF
   Output Parameters == wq_all
   Output Interval == <common_dt>
   Suffix == WQ
End Output

6.2.3.2 Files

The following output files are produced in the execution of an integrated simulation with data types as above. Each is a 2D or 3D (TUFLOW FV) map output that varies in time. Hyperlinks are provided to detailed descriptions in the appendices for representative pollutants:
