1D Integrity Tool - Tutorial

Introduction

The 1D Integrity Tool is a suite of tools that help modellers find and fix potential errors in 1D networks prior to running TUFLOW. The tool was primarily designed for sub-surface pipe drainage networks, but can be used for all 1D channel types, however not all checks will be available. The tool is designed to be fast and provide automated fixes as well as visualisations to help the process. The 1D Integrity Tool is a free tool that comes as part of the TUFLOW plugin in QGIS.

The 1D Integrity tool is designed to accept multiple inputs and will treat all inputs holistically as a complete system. Each tool is designed to be run separately and progressively as part of the entire tool suite. It is assumed that most of the channel attribute data has been populated, most importantly that each channel has been given a valid type.

The following exercises will take the user through the various tools using a pipe drainage network which contains a number of common errors which are found in these types of datasets.
