Flood Modeller 5.0 – Transform the way you undertake your flood risk modelling

Available now! The next generation of Flood Modeller, Jacobs’ industry-leading river, floodplain and urban drainage modelling, and real-time flood forecasting software, provides a wide-range of new features and capabilities that will transform the way you undertake your flood risk modelling, including the ability to model the drainage system using the new 1D urban solver.


Users with an existing Flood Modeller support and maintenance contract can upgrade their licence by visiting the Download section of our website.

If you’re new to Flood Modeller, please get in touch. We would be happy to recommend the most appropriate and cost-effective licensing solution. We offer monthly, annual and long-term licensing options and two editions of the software, all of which can be tailored to meet your project requirements.


What's new in Flood Modeller 5.0


Improve your understanding of flood risk

The new 1D urban solver enables you to quickly and efficiently undertake fully integrated catchment modelling by combining surface and sub-surface flow in a single model. Flood Modeller offers various solvers, which can be linked together, for all your needs: 1D urban for drainage and pipe networks, 1D river for water levels and 2D solvers for surface water flows. By simply loading an existing 1D urban model into Flood Modeller, you can save time importing and converting your data. It also provides a cost-effective solution as you no longer need to rely on third-party software.


Enhance your modelling experience

Quickly and easily manage large 2D result sets. Flood Modeller’s user-friendly interface allows you to build, run and visualise your models up to 10 times faster.


The new 2D modelling capabilities enable you to embed 1D structures directly within your 2D domain, simplifying your model build. If you need to model flow through a culvert, orifice or weir, and don't require a full 1D river network, the new automation wizard will automatically add these units to your 2D domain.


Accurately represent levee behaviour in 1D cross sections within Flood Modeller and calculate different levels across 1D sections between left bank, right bank and main channel.


Easily solve your modelling problems

With improved error messaging, more diagnostic and more guidance and documentation, you can now solve your modelling problems independently and more efficiently. Our online resources and dedicated support team are still available to help you with your modelling questions.


Flood Modeller 5.0 also offers over 30 other product enhancements which aim at delivering workflow efficiencies. For a detailed list of enhancements, download the release notes.


You can also fast track your learning with one of our CIWEM-approved training. You'll experience first-hand how to use Jacobs' industry-leading flood modelling software to enhance your modelling skills in an online environment from the comfort of your home.
