TUFLOW is a suite of advanced 1D/2D/3D computer simulation software for flooding, urban drainage, coastal hydraulics, sediment transport, particle tracking and water quality. With over 30 years of continuous development, TUFLOW is internationally recognised as the industry leader for hydraulic modelling accuracy, speed and workflow efficiency.
A key reason for TUFLOW's success is our support team of software developers and experienced modellers. They are renowned for their prompt, practical, helpful advice so that you can achieve your modelling objectives, and produce reliable, defendable solutions. We're here to help you solve your water modelling problems.
TUFLOW caters for all forms of free-surface and pipe network hydraulic modelling from complex 1D networks to 2D grid or quadtree meshes to 2D/3D flexible meshes. A full range of add-on modules are available to enhance TUFLOW's powerful core engines, including GPU acceleration, sediment transport, particle tracking and water quality simulation. Visit this products page for an overview and links to more information.
TUFLOW's 1D solver, often referred to as ESTRY, is the unsung hero of TUFLOW's success. With similar or more features than industry peers, the 1D solver supports all the functionality needed for detailed 1D modelling of: rivers and floodplains; a wide range of structures with dynamically adjusted energy losses; complex pipe networks including industry leading manhole loss algorithms; and logic driven operational structures.
TUFLOW's 2D Grid/Quadtree hydraulic modelling software leads the industry in accuracy, speed and workflow efficiency. In combination with TUFLOW's excellent 1D solver and best-in-class 1D/2D linking, TUFLOW 2D Grid/Quadtree is the preferred choice for simulating flooding, urban drainage with complex pipe networks, catchment hydrology, dam break, and storm tide or tsunami inundation.
TUFLOW's 2D/3D flexible mesh solver TUFLOW FV now leads the way for accuracy, speed and workflow efficiency in simulating estuarine, lake and coastal hydraulics, tsunami and storm tide propagation, advection/dispersion, sediment transport/morphology, water quality, and aquatic ecology processes.
TUFLOW models can be developed in a range of GIS software with free plugins available for ArcGIS/ArcPro, MapInfo and QGIS. The plugins greatly improve the efficiency of setting up models, reviewing results and production of maps and report quality charts. Choose the GIS development environment(s) that suits your preferences, needs, and budget, whilst utilising TUFLOW's powerful and easy to use scripting to make your modelling efficient and rewarding.
TUFLOW models can be developed within a range of Graphical User Interfaces (GUI) developed by our software partners: 12D Solutions, Flood Modeller Pro, GIS Mesher, SMS and Innovyze's XP-Solutions. These GUI options offer customised model development environments to suit your preferred style of operation and workflow. The 1D solvers offered by 12D, Flood Modeller and XP-Solutions are dynamically linked to TUFLOW's Fixed Grid/Quadtree 2D software.
Build on TUFLOW's core hydraulic engines with a range of optional add-on modules to create multi-use environmental models. Modules include: GPU acceleration; quadtree mesh refinement; 3D layering; advection-dispersion; sediment transport and morphology; particle tracking; water quality; and SWAN wave integration.
A large range of models are downloadable and can be run licence-free to support familiarisation with TUFLOW. The tutorial models come with step-by-step guidance on how to set up and apply TUFLOW, whilst demo models are provided to showcase how to apply specialised features - it's so much easier working from an example model than starting with a blank screen!
TUFLOW products are documented in detail via their user-acclaimed manuals and the Wikis. This provides access to thousands of modelling guidelines, tips, tricks, self-teach licence free model tutorials and much more. These user resources are further supported by a library of webinars, articles, publications and presentations. Visit the TUFLOW Library to access these valuable resources.
An extreme value analysis package for calculating the probability of flood flows based on historic gauge records developed by the University of Newcastle. Flike is compliant with the recent 2019 revision of the Australian industry guideline for flood estimation, "Australian Rainfall and Runoff (ARR)". TUFLOW provides a purchase and licensing service for the Flike software.
TUFLOW is the industry leader in benchmarked, accurate computer simulation software for a diverse range of applications: flooding assessments; infrastructure design and optimisation; dam break assessment; urban drainage; emergency response planning; coastal hydraulics; sediment transport; coastal, estuarine and freshwater receiving water quality assessments and much more.
