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

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.

Hardware

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. If you would like to complete the optional TUFLOW HPC steps utilising a GPU card then you will need access to a CUDA enabled NVidia graphics card.

Software

TUFLOW

This tutorial model has been constructed using the 2018 release of TUFLOW. The tutorial model may be simulated licence free using TUFLOW Build 2016-03-AC or later. This can be obtained from the downloads section of the TUFLOW website. TUFLOW Build 2016-03-AD or later must be used in order to take advantage of the free TUFLOW link for this tutorial model.

Flood Modeller

This tutorial model has been constructed using version 4.2 of Flood Modeller. This can be downloaded from the Flood Modeller Website. The tutorial model may be simulated licence free using Version 4.2 to 4.6. These versions of Flood Modeller contains the free TUFLOW link, which permits simulation of linked models with up to 10 links or the tutorial model.

Larger models with more links will require a link licence. A licence is also required is you intend to run the model in Flood Modeller 5 or later

GIS Software

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 and modelling packages:

• MapInfo
• QGIS
• ArcGIS

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 mtutorial is provided in a variety of different GIS compatible formats. Download the dataset that matches the GIS software you are using:

• ArcGIS Data Download

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.
