Linking Flood Modeller and TUFLOW | What are the benefits?

TUFLOW complements Flood Modeller's advanced 1D and 2D solvers and is suited to modelling rivers, overland flows and coastal hydraulics as well as inundation from storm tides. As agents for BMT, you can buy your TUFLOW licences and technical support directly from Jacobs.


Combining the capabilities of Flood Modeller and TUFLOW provides various benefits, and allows users to streamline their projects and undertake greater analysis.


Enhance your model build experience and result analysis

Flood Modeller's user-friendly interface offers an alternative to using GIS software as it enables users to build, run and visualise models within a single environment. It provides a range of tools to define the GIS components of a TUFLOW model by manipulating existing data or using the built in GIS functionality to 'draw' new elements onto a map.

By linking TUFLOW to Flood Modeller’s 1D river solver, users can benefit from a wide range of complex structures including gates, weirs, pumps and bridges. Logical rules can also be set up to represent a generalised logical controller, where output variables are set according to user-defined logical rules.


The data management tools within Flood Modeller enable TUFLOW modellers to store all of their model data within an organised project structure. This provides a clear record of the development of a model and the associated results.​


Dynamically link Flood Modeller to TUFLOW's ESTRY and Classic or HPC 2D solvers

Flood Modeller's leading 1D river solver can be seamlessly linked to TUFLOW (including ESTRY), enabling an integrated approach to modelling, combining open-channel, closed pipe and overland flow.


The link between Flood Modeller and TUFLOW allows flow (discharge) and water levels to be exchanged. It can be driven by either model with the exchange of information occurring at each multiple of the common time step.


Increased flexibility and choice - use the most appropriate modelling approach

Flood Modeller’s 1D network can be linked to multiple TUFLOW 2D domains, with each domain having a different time step and resolution. This provides both Flood Modeller and TUFLOW users with greater flexibility when producing an integrated model; use your preferred modelling method and the most appropriate model grid size for different parts of your study area.


Build upon existing models and link them together with minimal effort

Existing models can be linked together with little effort, making use of concepts already familiar to the modeller. Flood Modeller can be linked to TUFLOW via HX and SX boundaries so that level or flow information can be exchanged between the two models. This can also be translated to time and cost savings for projects where models or part of a model already exist in TUFLOW or Flood Modeller.


Run your simulations at lightning speed within Flood Cloud

When linking Flood Modeller to the TUFLOW, users can benefit from running models on a CPU or NVidia Tesla v100 GPU. Using NVidia GPU hardware can lead to considerably reduced simulation run times as demonstrated within BMT’s hardware benchmarking.


When users have many models to run and need results quickly, they can send their TUFLOW or 1D-2D linked Flood Modeller-TUFLOW models to the Flood Cloud service and run all their models simultaneously.

Customer success

Flood risk modelling of a steep watercourse, Greater Manchester, UK

Flood Modeller's 1D river solver was used to accurately model a steep watercourse in Greater Manchester. It aimed to produce a baseline model for the development of an Outline Business Case seeking to protect properties at risk of flooding.

Botany Bay Flood Risk Management Study, Australia

Flood Cloud enabled the Botany Bay project to run a range of design flood events for the updated flood study. 70 simulations were run in just 7 hours, providing simulation speed increases of between 75% and 98%.
