FM Tute M01 QGIS x1D Nodes

Introduction

This page describes the method of creating TUFLOW GIS based layers to reference the nodes within the Flood Modeller model

Method

1. Open the FloodModeller_Nodes. GIS layer from Module_Data\Module_01\gis folder.
2. Save as 1d_x1d_FMT_M01_nodes_001.shp within the TUFLOW\model\gis folder.
3. Open the GIS layer 1d_x1d_FMT_M01_nodes_001.shp_p within QGIS.
4. Interrogate one of the digitised points and inspect the attributes. Note that each point has a unique name which correlates to a RIVER, INTERPOLATE or REPLICATE unit within the Flood Modeller model. At junctions, both the upstream and downstream nodes must be digitised within this layer.

5. Save the file in preparation for reading into TUFLOW.

   Key Tip!

   The node IDs are case-sensitive as this is a requirement of Flood Modeller.
