== Introduction ==
Review the TUFLOW CATCH timeseries outputs:
Line 6 ⟶ 5:
** 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 instantaneous inflows and concentrations as a timeseries.
Additionally, review the TUFLOW HPC mesh results (.xmdf file) using the <u>[[TUFLOW_Viewer | TUFLOW Viewer]]</u>.

<li>Temperature has been provided as a timeseries with four input data points ('''temperature.csv'''). TUFLOW CATCH has interpolated these to produce temperatures at each timestep in the output timeseries file.<br>

== TUFLOW HPC Map Results ==
Review the TUFLOW HPC Map outputs with the TUFLOW Viewer:<br>
:'''Note:''' For further guidance on how to plot, view and style results, please refer to <u>[[TUFLOW_Viewer | TUFLOW Viewer]]</u>.
<ol>
<li> Load the '''2d_mat_TC01_001.shp''' layer from the '''TUFLOW\model\gis''' folder into QGIS.
<li>Open the TUFLOW Viewer from the TUFLOW Plugin toolbar.<br>
<br>
[[File:tuflow_plugin_tuflow_viewer.png]]<br>
<br>
<li>Open the simulation results. Select File > Load Results - Map Outputs. Navigate to the '''TUFLOWCATCH\results''' folder and select '''TC01_001_catchment_hydraulic.xmdf'''.
<li>In the TUFLOW Viewer panel, select 'Conc SED_CLAY' from the Result Type list. AsOutput the outputconcentration concentrationsvalues often vary significantly, makingwhich themcan difficultmake toresult interpret,interpretation itdifficult. isAdjusting recommendedthe symbology to adjusthave thea symbologysmaller concentration range, as shown in the video below., A smaller concentration range will enhance theimproves visibility of finer differences in the outputs. <br>

<li>Review the pollutant concentrations of clay and E. coli throughout the model simulation. NoticeObserve how the water flowsmoves over theacross different material regions.
:'''Note:''' The symbology of 'Conc WQ_PATH_ECOLI_ALIVE_CFU_100ML' has been updated similarly to above.
<br>

<li>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. <br>
<br>
{{Video|name=animation_TC1_results_03a.mp4|width=1432}}<br>
<li>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 runsreduces offwhen rainfall occurs. <br>
