A 1D open channel requires cross sections for processing of the channel geometry. For each cross section there is an individual comma separated csv file:
<ol>
<li>Load in the '''1d_xs_M11_channels_001_L''' layer from '''Module_11\TUFLOW\model\gis\M11_001.gpkg''', either:
:*Within the QGIS Browser Panel, navigate to '''M11_001.gpkg''' and double click the layer, or
:*In File Explorer, drag and drop the '''M11_001.gpkg''' into the QGIS workspace and select the layer.
Line 67 ⟶ 64:
A 1d_nwk layer is used to model open channels. It contains information on inverts and to obtain data from the cross section the 1d_nwk and 1d_xs must be snapped:
