Within the QGIS Browser Panel, navigate to the '''Module_10\Tutorial_Data''' folder. Drag and drop the following layers from their separate databases into the '''Module_10\TUFLOW\model\gis\M10_001.gpkg''' database: <br>
:*'''2d_zsh_M10_damwall_001_L'''
:*'''2d_vzsh_M10_dambreak_001_R'''
Line 33:
<ol>
<li>Open the files, either: <br>
:*Within the QGIS Browser Panel, navigate to '''Module_10\TUFLOW\model\gis\M10_001.gpkg''' and double click the layers, or
:*In File Explorer, drag and drop the '''Module_10\TUFLOW\model\gis\M10_001.gpkg''' into the QGIS workspace and select the layers (hold Ctrl to select multiple).
<li>The 2d_zsh line layer represents the dam wall:
:*A ‘Z’ attribute of 65 is specified, the elevations are set to 65 metres along the length of the line.
:*The line has the same Shape_Width as the cell size, this is a thick breakline modifying whole cells.

<br>
<li>The 2d_vzsh polygon layer represents the location of the dam break:
Line 45:
:*Trigger_Value sets the simulation time in hours that the dam break is to commence. A value of 1 indicates the dam break begins at 1 hour.
:*Period sets the time in hours over which the change in elevation occurs. A value of 0.25 sets a period of 15 minutes replicating the break.

Increment the 2d_bc layer from Module 01 and remove the upstream inflow:
<ol>
<li>Load in the '''2d_bc_M01_001_L''' layer from '''Module_10\TUFLOW\model\gis\M10_001.gpkg''', either:
:*Within the QGIS Browser Panel, navigate to '''M10_001.gpkg''' and double click the layer, or
:*In File Explorer, drag and drop the '''M10_001.gpkg''' into the QGIS Workspace and select the layer.
Line 68:
<li>Use the 'Apply TUFLOW Styles to Current Layer' tool.
<li>Click on the ‘Increment Selected Layer’ symbol from the TUFLOW Plugin toolbar.
<li>Within the 'Increment Selected Layer' tool window:
<li>Update the 'Output Layer Name' to '''2d_bc_M10_001_L'''. :*Ensure the 'Output Database' is '''M10_001.gpkg'''.
<li>Click 'OK'.<br>
<li>The tool removes:*Ensure the source'Output layerLayer fromName' the Layers panel and theis '''2d_bc_M10_001_L''' appears.
:*Select 'Remove Source Layer from Workspace'.
:*Select 'Increment Layer only' and click 'OK'.
The tool removes the source layer from the Layers panel and the '''2d_bc_M10_001_L''' appears.<br>
See <u>[[QGIS TUFLOW Increment Layer | Increment Layer Tool]]</u> for more information.
<li>Right click on the '''2d_bc_M10_001_L''' layer to toggle on Editing.
<li>Zoom to the upstream inflow, select and delete the line.
<li>Click 'OK' and turn off editing to save the edits.<br>
