Take your modelling

to the next level

Flood Modeller allows you to quickly  and efficiently undertake fully integrated catchment modelling by combining surface and subsurface flow in a single model. Obtain a detailed understanding of flood risk in urban areas and understand how drainage systems interact with surface water and river flows. 

Quick to learn and

intuitive to use

Flood Modeller provides a user-friendly environment for building, running and visualising flood models. It's GIS-like interface offers superior workflows and support for multi-screen working. Incorporate online background mapping or web mapping services to bring your models to life, whilst ensuring an accurate representation.

Accelerate your project


Integrated with Flood Modeller, our award-winning Flood Cloud service enables you to seamlessly run your flood modelling simulations in the cloud. It empowers users to run compute-intensive simulations faster, at greater scale, and more cost effectively than ever before.

Flexible licensing and

pricing structure

With three editions of Flood Modeller to choose from,  and multiple licensing options, you can select the most appropriate and cost-effective solution for your organisation. You can also enhance your modelling experience as and when required with our range of add-ons.

Case studies

A flood risk assessment for the EXPO 2020 rapid transit rail system extension involving integrated hydrologic analysis with detailed 2D hydraulic modelling of the urban areas. Flood Modeller was chosen due to its ability to accurately model complex flows in urban environments.


2D modelling of urban flooding, Dubai, UAE

A catchment scale study with over 270 km of embankments, 40 separate pumps, and long duration flood events. Flood Modeller was selected due its ability to model complex structures and their operational control and the robustness of its solvers.


Complex structures and operational rules, England

Flood Modeller's 1D and 2D ADI solvers have been applied to simulate combined fluvial and direct rainfall flooding in a sub-catchment of the Parramatta River in Sydney. They were selected for their speed and stability.
