Line 4:
<li>Open the '''Water_Level_Lines.shp''' layer from the Module_Data\Module_01\gis folder.</li>
 
<li> Open the project GeoPackage file <b>M02_5m_002.gpkg</b> in the Browser Panel. Drag and drop the layer <b>FloodModeller_Nodes_P'''Water_Level_Lines.shp</b>''' into the project GeoPackage file <b>M02_5m_002.gpkg</b>. Re-name the layer <b>1d_x1d_WLL_FMT_M01_001_L.gpkg</b>. The _x1d_ in the name flags that the Water Level Lines will be linked to an external 1D network, in this case a Flood Modeller network, rather than a 1D ESTRY network. </li>
 
Save as '''1d_x1d_WLL_FMT_M01_001_L.shp''' within the FMT_M01\TUFLOW\model\gis folder. The _x1d_ in the name flags that the Water Level Lines will be linked to an external 1D network, in this case a Flood Modeller network, rather than a 1D ESTRY network.</li>
 
<li>The 1d_wll layer must be digitised perpendicular to the flow direction and from left to right looking downstream. An attribute of '2.5' is specified for all lines as a minimum distance interval along the WLL to generate triangulation points.</li>
