Line 1: = Introduction = 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>[[Tutorial_M01_Results_QGIS \| 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 from~~Open the TUFLOW ~~Plugin toolbar~~Viewer. <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> {{Video\|name=Animation_M06_Results_002_01b.mp4\|width=1262}}<br> ~~[[File:Animation M06 GIS 002 01a.gif]]<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>~~ <br> {{Video\|name=Animation_M06_Results_002_02b.mp4\|width=1262}}<br> ~~[[File:Animation M06 GIS 002 02a.gif]]<br>~~ <br><br>▼ </ol> ▲<br> =Conclusion= :The cumulative rainfall, rainfall rate and rainfall material losses derived from rainfall polygons were inspected with the TUFLOW Viewer. ~~:Polygons have been digitised based on input rainfall hyetographs.~~ :*For further functionality, see <u>[[TUFLOW_Viewer \| TUFLOW Viewer]]</u>.<br> <br>▼ ▲<br> {{Tips Navigation \|uplink=[[Tutorial_M06#Results_2\| Back to Module 6 Main Page]]
