=Introduction=
QGIS is used to view the cumulative rainfall and rainfall rate with the TUFLOW Viewer. For viewing of the 2D map results, see <u>[[Tutorial_M01_Results_QGIS | Module 1]]</u>.<br>

= TUFLOW Project Re-Configuration =
Re-configure the TUFLOW project to use and save empty files to the correct folder:<br>
<ol>
<li>Go to Plugins > TUFLOW > Editing > Configure / Create TUFLOW Project.
<li>Change the folder which contains TUFLOW to the '''Module_06''' folder. This is the only change required, the model folder structure and template empty files are supplied from previous model.<br>
Note: The 'results' and 'check' folder get automatically created when the TUFLOW model is run. <br>
<li>Click 'OK' and save the QGIS workspace by selecting Project > Save As.<br>
<br>▼
[[File:M06 Configure Project v3.png]]<br><br>
<li>Set the QGIS workspace projection to EPSG:32760, see <u>[https://wiki.tuflow.com/index.php?title=Tutorial_Site_Familiarisation_QGIS#Set_the_Projection Set the Projection]</u>.
</ol>

<li>Open the TUFLOW Viewer.
<li>Select File > Load Results. Navigate to the '''M06_5m_001.tcf''' in the '''Module_06\TUFLOW\runs''' folder and open it.
<li>Select 'Water Level' under the Result type and scroll through output times to review flood extent from rain on grid model. <br>

<li>Three additional output types appear in the Result Type panel:
*RF Cumulative: the cumulative rainfall in mm over time.
*RF Rate: the rainfall rate in mm/hr over time.
*Manning n: the Manning n values over time.<br>
These outputs are inclusive of any boundary adjustments (made in the bc_dbase) and rainfall losses (applied in the materials file).
<li>Use the Plot Time Series tool to see the time series of the cumulative rainfall and rainfall rate at a point:<br>

<br>
<li>Add multiple points across the grid. Notice they all have an equal cumulative rainfall and rainfall rate applied. <br>

<br>
<li>Use the Plot Time Series tool to see the time series of the depth and manning's n at a point and turn on the 'Manning n' map output from the Results Type to see the manning's n value change with depth:<br>

=Conclusion=
:*Flood extent from a rain on grid model was inspected.
:*The cumulative rainfall and rainfall rate derived from global rainfall were inspected at a point.
:*The manning's n value was inspected as it varied in relation to depth.<br>
:*For further functionality, see <u>[[TUFLOW_Viewer | TUFLOW Viewer]]</u>.<br>
