Flood Modeller Tutorial Model
Introduction
The objective of this Flood Modeller – TUFLOW model is to demonstrate the ability of TUFLOW to link to an external 1D scheme and the various methods available in which to create this link. It is designed to supplement existing documentation and assumes the user has some prior knowledge of both the Flood Modeller and TUFLOW software packages. This tutorial model has been developed by BMT with Jacobs. Please post comments, requests and feedback to support@tuflow.com.
Requirements and Downloads
Both TUFLOW and Flood Modeller have relatively modest system requirements for small models such as the tutorial model. However, larger and more complex models may have higher hardware requirements - in particular memory (RAM). Both software are available in 32 and 64 bit versions. The tutorial model is designed to be small, to allow for quick simulation and load times. The tutorial model should run on any modern PC or laptop that is capable of running Windows 7 or later.
| Requirement | Brief Description | Download |
|---|---|---|
| TUFLOW | TUFLOW is a computer program for simulating depth-averaged, one and two-dimensional free-surface flows such as occurs from floods and tides, with the 2D solution occurring over a regular grid of square elements. It is commonly used in the UK and Ireland, Australia and the United States for the modelling of surface waters, river systems and pipe networks. It is recommended to always use the latest release version of TUFLOW. This tutorial model does not require a TUFLOW licence. This tutorial is set up to use a NVIDIA GPU card. If this is not available, CPU can be used in the hardware command. |
The TUFLOW executable is provided within the Tutorial Dataset. |
| Flood Modeller | Flood Modeller (previously known as ISIS) is a commercial flood modelling package developed by Jacobs for simulating depth-averaged one and two dimensional free surface flows. It is primarily used for the simulation of river channels and is widely used within the UK and Ireland. This tutorial model will only leverage Flood Modeller’s 1D Solver. TUFLOW 1D and 2D domains can be dynamically linked to the 1D domain of Flood Modeller Pro. Flood Modeller is not included within the TUFLOW executable and must be downloaded separately. Unlike TUFLOW Flood Modeller has a standalone Graphical User Interface which can be used to build networks, run models, and visualise results. It is recommended that TUFLOW 2020-10-AD or later is used in conjunction with Flood Modeller Version 5 or later. For Flood Modeller Version 5 or later a Standard, Professional, or Unlimited Edition of Flood Modeller Pro is required to open and run the tutorial model. |
Latest 64-bit version of Flood Modeller. |
| QGIS QGIS TUFLOW plugin |
The Geographic Information System (GIS) used to build models and view results. This tutorial was developed with QGIS 3.20. It is recommended to have QGIS 3.20 or later to ensure compatibility with TUFLOW plugin latest features. The TUFLOW plugin includes numerous tools to increase workflow efficiency. |
Latest 64-bit version of QGIS. |
| NotePad++ Syntax Highlighting |
A text editor is required for creation of the TUFLOW input files. This tutorial was developed with NotePad++. Ideally a text editor should be able to:
TUFLOW colour coding can be enabled using syntax highlighting. |
Latest 64-bit version of Notepad++. TUFLOW syntax highlighting for Notepad++. For instructions on configuring Notepad++ for TUFLOW modelling, see Notepad++ tips. |
| Microsoft Excel | A spreadsheet software is required for working with tabular data and .csv files. This tutorial has been created in Excel. |
TUFLOW models typically require access to a GIS package, text editor, Microsoft Excel and a results viewer to build, review and visualise a model. Refer to the following Wiki page to view a list of compatible packages. Alternatively, Flood Modeller may be used as a GUI for creating and editing GIS layers in a TUFLOW model and also for visualising the results. Instructions for this Flood Modeller – TUFLOW tutorial model have been provided using the following GIS file formats:
- QGIS - SHP
- QGIS - GPKG
Module Data
All data to complete the tutorial has been provided, including a digital elevation model (DEM), aerial photography and a complete Flood Modeller model. Data for this tutorial is provided in a variety of different GIS compatible formats. Download the dataset that matches the GIS software you are using:
Recommended Reading
The aim of this tutorial is to demonstrate the steps undertaken to build, review and visualise the results of a linked Flood Modeller – TUFLOW model. It assumes that the user has a good understanding of both the 1D component of Flood Modeller and the 1D and 2D components of TUFLOW. The following resources may be of use:
- TUFLOW Tutorial Model
- TUFLOW User Manual
- Flood Modeller 1D Quick Start Guide
- Flood Modeller User Manual
Modules
The tutorial is presented over a series of modules, with each module offering the opportunity to run the model and review the results. Each of the modules builds upon the previous iteration with models developed in the previous module made available. New users are advised to undertake the modules in sequence, whilst more experienced users can skip to modules containing specific features of interest.
Module 1: Linking Flood Modeller to TUFLOW
The first tutorial module introduces the user to the linking of a TUFLOW 2D domain to a 1D Flood Modeller model. To access this module of the tutorial please see this page: Flood Modeller Tutorial Module 1.
From this tutorial you will learn how to link an existing Flood Modeller 1D model to a TUFLOW 2D domain.
This tutorial is ideal for those starting to learn how to link Flood Modellder and TUFLOW.
Module 2: Linking Flood Modeller to ESTRY
The second tutorial demonstrates the linking of an ESTRY pipe network to an existing Flood Modeller – TUFLOW linked model. To access this module of the tutorial please see this page:
Flood Modeller Tutorial Module 2.
From this tutorial you will learn how to add a 1D pipe network and connect it to the representation of the watercourse created in Flood Modeller and link it to the TUFLOW representation of the floodplain created as part of Flood Modeller Tutorial Module 1. This tutorial is ideal for those who would like to learn more about the interaction of TUFLOW with Flood Modeller including the simulation of fully integrated drainage systems.
