TUFLOW 2011

Workshops

TUFLOW FV - Session 1(Download PDF)

TUFLOW FV is a 2D/3D flexible mesh, finite volume numerical model that simulates hydrodynamic, sediment transport and water quality processes in oceans, coastal waters, estuaries and rivers. The overview will introduce the concepts of flexible mesh modelling--how it differs from finite difference/fixed grid models (like TUFLOW), the advantages and disadvantages and when to use.

Urban Modelling - Session 2(Download PDF)

Tips and tricks for modelling urban areas and pipe networks. Manhole energy losses explained and efficient ways of managing and setting up large pipe networks demonstrated. Different approaches for modelling overland areas including buildings and fences in 2D are also presented.

Enhanced Output - Session 3(Download PDF)

How to make your TUFLOW model output much better! This workshop will give you GIS techniques for producing high quality flood maps, using the new XMDF files, and how to produce impressive 2D and 3D animations using SMS and ArcGIS.

TUFLOW 2012: New Features - Session 4(Download PDF)

Bill Syme will give a brief overview of new features in TUFLOW for 2011. These include full .shp and .xmdf file support, ISIS-TUFLOW-PIPE (ISIS-ESTRY link), flexible output options, TUFLOW Wiki, new SA options, new infiltration options, new 1D structures, updated utilities, and more. He will also discuss the TUFLOW event and scenario features which offer the user a very powerful tool to the point where all simulations can be initiated using the one .tcf file.

Boundary Conditions - Session 1(Download PDF)

This workshop will comprise a presentation on TUFLOW hydraulic controls and reliable representation of the physical process at outflow boundaries. This will be held in conjunction with a discussion on practical applications of fluvial and rainfall hydrology within a TUFLOW model.

Hydraulic Structures - Session 2(Download PDF)

This workshop will be about methods for the modelling of buildings, fences and other hydraulic structures which have no explicit representation in TUFLOW. A variety of different techniques for representing buildings and fences in a two-dimensional domain will be presented, along with some of the pros and cons of each. Discussion in the workshop will then focus on the attendees' experiences of this aspect of urban modelling, how some of the methods can be implemented using commonly available data sources and which of the methods might be appropriate for any particular problems that the attendees might have.

Bridge Modelling - Session 3(Download PDF)

This workshop will cover how to model bridge and culvert structures in TUFLOW using embedded ESTRY units, direct modelling in 2D and ISIS TUFLOW. The latest recommendations from various sources will be presented. There will be brief consideration for potential approaches to modelling bridges and there will be discussion of participants' experiences and problems with bridge modelling.

TUFLOW for Beginners - Session 1

The objective would be to introduce TUFLOW to new users so that they can understand the principles of TUFLOW and benefit from the rest of the day. This will cover the basics of setting-up a TUFLOW model and a discussion of TUFLOW file structures.

Developing Skills - Session 2(Download PDF)

For more experienced users the objective would be to build on people's existing experience so that they are able to address more complex issues including optimising simulation times, TUFLOW hot-start/restarts, schematisation of boundary conditions, multiple domains and 1D linking to ESTRY. This workshop included some handouts (B&W).

Healthy Models & Debugging - Session 3(Download PDF)

This workshop will concentrate on the production of healthy models including checking for terrain problems; tracking the causes of instability using TUFLOW diagnostics files and basic advice on building a healthy model such as 2D linking across embankments, boundary positioning, modifying time steps (when and when not to reduce), LiDAR patching and z shape merging, representation of ditches, parallel rivers and general good practice.

ISIS-TUFLOW Linking - Session 4(Download PDF)

An interactive presentation relating to ISIS-TUFLOW linking and will cover the following subject areas: model preparation; data transfer between ISIS and TUFLOW; HX verses SX boundaries and fixing model instabilities at the interface of ISIS and TUFLOW. This will be supported by the use of worked examples.

User Group

TUFLOW 2011 and Beyond - Syme(Download PDF)

Bill will present new features in TUFLOW for the 2011 release and beyond, and new on-line services such as the TUFLOW Wiki. Case studies will be used to demonstrate the features.

Bridge Obstruction in Lower Ely River - Yang(Download PDF)

A linked 1D-2D ISIS-Tuflow modelling was carried out to predict the flood risk in Canton, Cardiff where historical flooding was recorded due to bank over-topping from the River Ely. The main challenge of the modelling was that the urban area exhibited highly variable topographical elevations at a number of junctions between railway, highway and the residential streets. An additional challenge came from the river bridge that presents a significant obstruction in the river cross-section. The ISIS-Tuflow model was therefore targeted detailing the complexity of the local topography and representing the bridge to create a highly accurate local model to assist with the NEECA2 flood mitigation scheme. The model was calibrated using recorded hydrometric and historical property flood data. It is encouraging that the calibration indicated satisfactory agreements between the historical data and the modelling results. This flood modelling application concludes that Tuflow is one of the best practice tools for modelling urban flooding.

ISIS-TUFLOW-PIPE Link - Adams(Download PDF)

The ISIS-TUFLOW link has been extended due to popular demand to include a link the 1-d component of TUFLOW (ESTRY). This development, which became available in early October, enables the complementary strengths of ISIS and TUFLOW to be used together in the same model. Konrad will give an overview of the development and usage of ISIS-TUFLOW-PIPE link, and other recent enhancements, and provide examples of its applications.

Rating Curve Assessments - Craig(Download PDF)

There are various methods available for rating curve assessment and extensions, including 1D, linked 1D-2D and 3D modelling. The presentation will discuss the strengths and limitations of different methods with respect to a range of situations, using specific sites to show examples of some good practice and share some pitfalls that you may wish to avoid.

Cambridge SWMP - Young(Download PDF)

John Young will discuss the direct rainfall modelling undertaken for the Cambridge Surface Water Management Plan paying particular attention to the post processing of the output of the data. This will include evaluation of flood damages, economic analysis and assessment of engineering options to generate a long term strategy for the alleviation of surface water flooding in Cambridge.

Queensland Floods: Where to from here? - Syme(Download PDF)

The Queensland floods of January 2011 were the worst in over a century. Bill will delve into his other passion: the need for proactive floodplain management. He will discuss what was learnt and where to from here.

Application of TUFLOW FV to River and Storm Surge Modelling - Nielson(Download PDF)

Chris Nielsen and Phillip Ryan will discuss TUFLOW-FV and how it has been used to model a variety of physical processes, including coastal hydraulics, ocean currents, river flooding and storm surge and, more recently, 3D flows in rivers and 3D water quality. Case studies of 2D storm surge modelling and 3D river modelling are presented in this session.
