QGIS is used to view the cumulative rainfall, rainfall rate and material rainfall losses with the TUFLOW Viewer. For viewing of the 2D map results, see <u>[[Draft_viewing_results_M01 | Module 1]]</u>.<br>
QGIS is used to create, import and view input data.<br>
<br>
 
= Method =
Inspect cumulative rainfall, rainfall rate and loss outputs:
Create a 2d_rf layer with digitised polygons based on the input rainfall hyetographs:
<ol>
<li>Click on the ‘Import Empty File’ tool fromOpen the TUFLOW Plugin toolbarViewer.
<li>Select File > Load Results. Navigate to the '''M06_5m_002.tcf''' in the '''Module_06\TUFLOW\runs''' folder and open it.
<li>Select '2d_rf' from the Empty Type list.
<li>One additional output type appears in the Result Type panel:
<li>In the Run ID box write: 'M06_polygons_002'.
:*Cum. Mat. Loss: the total rainfall losses applied as initial and continuing losses specified in the materials file.
<li>Tick the 'Regions' Geometry Type and hit 'OK'. The 2d_rf appears in the QGIS Layers panel.<br>
<li>Use the Plot Time Series tool to see the cumulative material loss time series. Notice the variation due to the assigned materials ID:<br>
</ol>
The same catchment breakup is used as the 2d_sa layer:
<ol><li>Navigate to the '''Module_06\TUFLOW\model\gis''' folder and open the '''2d_sa_M01_001_R.shp''' layer in QGIS.
<li>Copy and paste the polygons from the 2d_sa layer into the 2d_rf: <br>

<br>
<li>Use the Plot Time Series tool to see the time series of the cumulative rainfall, rainfall rate and losses at a point. Notice the results vary spatially due to the 2d_rf polygons and 2d_mat regions: <br>
<li>Open the attribute table and make the following edits:
:*Update names to match the names in the '''rainfall_station.csv''' input data (RF_FC04, RF_FC05, RF_FC06, RF_FC07)
:*f1: 1
:*f2: 1 <br>
The attributes f1 and f2 are multipliers adjusting the rainfall spatially. No adjustments are made, a value of 1, e.g. 100% of specified rainfall is used. <br>
<li>Turn off editing to save the edits.<br>

=Conclusion=
:*The cumulative rainfall, rainfall rate and rainfall material losses derived from rainfall polygons were inspected with the TUFLOW Viewer.<br>
:*Polygons have been digitised based on input rainfall hyetographs.
