= Introduction = 
QGIS is used to view the grid and mesh 2D results:
:*The grid results (.tif) are inspected with the Profile Tool plugin. For installation, see <u>[https://wiki.tuflow.com/index.php?title=QGIS_Profile_Tool Installation of Profile Tool]</u>
:*The mesh results (.xmdf) are inspected with the <u>[[TUFLOW_Viewer | TUFLOW Viewer]]</u> which is part of the TUFLOW plugin. For installation, see <u>[https://wiki.tuflow.com/index.php?title=TUFLOW_QGIS_Plugin#Installation_of_Plugin Installation of TUFLOW Plugin]</u>.<br>
<br>

=Method=
View grid results with Profile Tool:<br>
<ol>
<li>Load the '''M01_5m_001_h_Max.tif''' file from the '''Module_01\TUFLOW\results\grids''' folder. It can either be dragged and dropped into QGIS, or loaded by selecting Layer > Add Layer > Add Raster Layer from the menu.
<li>This displays the maximum water level in the model recorded during the whole simulation.
<li>Use the Profile Tool to view the maximum water level and DEM.<br>

View mesh results (Map Outputs) with TUFLOW Viewer:<br>
<ol>
<li>Open the TUFLOW Viewer from the TUFLOW plugin toolbar:<br>
<br>

<br>
<li>Load the results using the TCF. From File > Load Results, navigate to the '''Module_01\TUFLOW\runs''' folder and select the '''M01_5m_001.tcf''' file. This option uses the file paths within the TCF to load both types of results, Map Outputs and Time Series.<br>
Note: The same File > Load Results option can be used when loading from the '''M01_5m_001.tlf''' file written in the '''Module_01\TUFLOW\runs\log''' folder. <br>
<li>Alternatively, open the Map Outputs and Time Series results independently using:
:*Load Results - Map Outputs > select map output mesh results file (.xmdf)
:*Load Results - Time Series > select time series output results (.tpc)
<li>The Map Outputs show scalar datasets, e.g. depth and velocity, and vector datasets, e.g. velocity vectors. Only one scalar and one vector dataset can be displayed at the same time.<br>
<br>

<li>Select '''M01_5m_001''' from the Open Results list, click on a scalar dataset 'Depth' under the Result Type and scroll through the output times. The results update as new output times are selected. </li>
Note: The styling of the Map Outputs can be changed by right clicking on each result dataset and editing the 'Properties'. <br>
<br>
{{Video|name=Animation_M01_Depth_c.mp4|width=1265}}<br><br>
<li>Click on a vector dataset 'Vector Velocity' to add it to the displayed 'Depth' and visualise them together. The vector output shows both direction and magnitude. <br>
Note: The appearance of vectors can be be changed. Right click on 'Vector Velocity' and edit the 'Properties'. <br>

</ol>
View mesh results (Time Series) with TUFLOW Viewer from the 2d_po files:
<ol>
<li>Using the 'Select Features' tool, select the '''M01_5m_001_PLOT_L''' line, and select the Flow dataset from the Time Series Result Type. This shows the flow data across the 2d_po line (Type Q_).
<li>View the point time series for Level and Velocity dataset (Type H_ and V_) by selecting the '''M01_5m_001_PLOT_P''' in the Layers panel and the point.
