FM Tutorial M02 QGIS SHP Flood Modeller1D/ESTRY 1D Link: Difference between revisions

<li>Observe that an additional node "DSBDY" is present within the updated Read GIS ISIS Nodes layer '''1d_x1d_FMT_M01_nodes_002_P.shp''' at the downstream end of the Flood Modeller network.

 

 

<li>Create a new folder entitled '''xs''' in the '''TUFLOW\model''' folder. Copy the layer '''1d_xs_FMT_M02_creek_001_L.shp''' and the csv files listed below from the '''Module_data\Module_02\Creek''' folder into the newly created '''TUFLOW\model\xs''' folder. These csv files in combination with the layer '''1d_xs_FMT_M02_creek_001_L.shp''' will be used to define the geometry and locations of the river channel cross sections.

<li>As there is gap between the final node of the Flood Modeller network and the start of the ESTRY network a connector "X" type channel type must be digitised to connect them. Turn on Toggle Editing for the layer '''1d_nwk_FMT_M02_channels_001_'''L and digitise a polyline from the first vertex of the ESTRY channel to the Flood Modeller node. Specify the Type "X" for the digitised channel. Save the changes.

<li>To complete the "X1DQ" link a manually created ESTRY node must be snapped to the Flood Modeller node and have a "Conn_1D_2D" attribute of "X1DQ" specified. To do this, import an empty 1d_nwke_empty_P.shp layer from within the FMT_tutorial\FMT_M02\TUFLOW\model\gis\empty folder.
