TUFLOW CATCH Tutorial M01 Results QGIS

Introduction

Review the TUFLOW CATCH timeseries outputs:

• Mass balance files
  • Surface water: Cumulative surface water flow and associated pollutant masses leaving the TUFLOW HPC model and entering the receiving polygon.
  • Groundwater: Cumulative groundwater water flow and associated pollutant masses leaving the TUFLOW HPC model and entering the receiving polygon.
  • Total: The combined data from the above surface water and groundwater mass balance outputs.
• Receiving polygon inflows and concentrations

Additionally, review the TUFLOW HPC mesh results (.xmdf file) using the TUFLOW Viewer.

TUFLOW CATCH Timeseries Outputs

Review the time series data for the receiving polygon:

1. In Windows File Explorer, navigate to the TUFLOWCatch\bc_dbase folder and open TC01_001_catchment_hydraulic_receiving.csv.
2. This file contains incoming flow and concentrations at an interval of 5mins. This interval is defined via the what command?? == ?? command in the .tcc.
3. Salinity and dissolved oxygen are both constant, so the outputs should be constant throughout the entire simulation.
   
   File:Graph of constant pollutants over time
   
   
4. Alive and dead E coli have been defined with the same pollutant export parameters, so their outputs should be equal.
   
   File:Graph of ecoli over time?
   
   
5. what to say about flow vs pollutant?
   
   File:Graph of flow vs pollutant concentrations, pathogens on separate graph
   
   

   Note: The pathogen concentrations are plotted on a logarithmic scale.

Review the mass balance time series data:

1. In Windows File Explorer, navigate to the TUFLOWCatch\bc_dbase folder and open TC01_001_catchment_hydraulic_mass_balance.csv.
2. This file contains the total of the surface and groundwater flow (m^3) and associated pollutant masses leaving the TUFLOW HPC model to the receiving polygon. The outputs are written in the same interval as the TC01_001_catchment_hydraulic_receiving.csv.

TUFLOW HPC Map Results

Review the TUFLOW HPC Map outputs with TUFLOW Viewer:

1. Load the 2d_mat_TC01_001.shp layer from the TUFLOW\model\gis folder into QGIS.
2. Open TUFLOW Viewer from the TUFLOW Plugin toolbar.
   
   
   
   
3. Open the simulation results. Select File > Load Results - Map Outputs. Navigate to the TUFLOWCatch\results folder and select TC01_001_catchment_hydraulic.xmdf.
4. In the TUFLOW Viewer panel, select 'Conc SED_CLAY' from the Result Type list. As the output concentrations often vary significantly, making them difficult to interpret, it is recommended to adjust the symbology as shown in the video below. A smaller concentration range will enhance the visibility of finer differences in the outputs.
   
   
   
5. Review the pollutant concentrations of clay and E. coli throughout the model simulation. Notice how the water flows over the different material regions.
   
   
   
6. Zoom in to the downstream end of the model. Use the Plot Time Series tool to see the pollutant concentrations at various locations around the receiving polygon. These time series concentrations should be similar to the TC01_001_catchment_hydraulic_receiving.csv output.
   
   
   
7. Select 'Dry Mass WQ_PATH_ECOLI_ALIVE_CFU_100ML' from the result type list. This is the dry mass of the accumulated alive E. coli. Notice that at the start of the simulation, there is no dry mass, but as the model continues, the dry mass accumulates on the paddocks, and then runs off.
