<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 '''Water_Level_Lines.shp''' into the project GeoPackage file <b>M02_5m_002.gpkg</b>. Re-name the layer <b>1d_x1d_WLL_FMT_M01_001_L</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>
