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 WBM with CH2MHill. Please post comments, requests and feedback to the Discussion Page or contact support@tuflow.com.

Requirements

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 XP or later.

Software

TUFLOW

TUFLOW build 2016-03-AB or later is required for this tutorial model. This can be obtained from the downloads section of the TUFLOW website. It is recommended that you use the latest release version of TUFLOW, both 32 bit and 64 bit versions are available. This tutorial model does not require a TUFLOW licence in order to be simulated, and no additional drivers should be required.

Flood Modeller

Version 4.2 of Flood Modeller or later is required for this tutorial model. Currently, a valid license for Flood Modeller and the TUFLOW link is required to simulate this tutorial model however we are currently working with CH2MHill to allow for this model to be simulated license free.

GIS Software

TUFLOW models typically require access to a GIS, 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
• Flood Modeller

Module Data

Some model data is provided including a digital elevation model (DEM), aerial photography and a working Flood Modeller model. The required background model data for the tutorial model is available for download on the TUFLOW website. If you wish to run all of the final models for each module you can use the batch file under Complete_Model\Tuflow\runs\_run_all.bat. Before using the batch file you may need to edit the file in a text editor and change the path to the executable (ISISf32.exe), save then double click on the .bat file in Windows Explorer to initiate the simulations.

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.

Module 2: Linking Flood Modeller to ESTRY (x1DH)

The second tutorial demonstrates the linking of an ESTRY pipe network to an existing Flood Modeller – TUFLOW linked model.

Module 3: Linking Flood Modeller to ESTRY (x1DQ)

The third tutorial demonstrates the linking of an existing Flood Modeller – TUFLOW model that outfalls to an ESTRY network.
