Introduction
In this tutorial we will add a representation of a proposed development which involves adding TUFLOW 1D pipe network elements into the existing model network to represent the drainage network, which will then be linked with Flood Modeller Pro.
This will involve:
- Modification of the floodplain topography by the creation of a 3D TIN surface;
- Revising the land use;
- The addition of pipes and pits to represent an underground drainage network;
- Linking the pipe network to Flood Modeller; and
- The addition of an inflow into the pipe network.
GIS Inputs
The steps necessary to modify each of the GIS inputs are demonstrated in MapInfo, ArcGIS and QGIS. At each stage please select your GIS package to view relevant instructions.
Define Elevations (Building a TIN)
We have provided the GIS layers necessary to modify the ground elevations to represent the proposed development. This part of the tutorial will demonstrate how a TIN is created from these GIS layers. We will also update the GIS defining the road crest level. Follow the instructions below for your preferred GIS package
